Electric code calculator

Electricians constantly perform NEC calculations (conduit fill per Chapter 9, ampacity/wire sizing per Table 310.16, voltage drop, box fill per Article 314.16, and load calcs) by flipping through dense, frequently revised code books or generic calculators. The NEC changes every three years and the 2023 edition added nine new articles, deleted three, and revised many titles, so a manual or outdated reference produces errors that cause failed inspections, rework, callbacks, and liability.

Rubric version: INAV-VALIDATION-2026-06-04 / generated July 8, 2026

Demand signal

24% weight

6/10

Demand looks thin because the report has 4 source-backed signal(s), an editorial confidence of 58/100, and a defined buyer in Electrical trades software and field-reference tools serving residential, commercial, and industrial electrical contractors in the US (and Canada via CEC)..

BLS Occupational Outlook Handbook: electricians held about 818,700 jobs in 2024, median wage $62,350 (May 2024), with employment projected to grow 9% from 2024 to 2034 and roughly 81,000 openings per year — a large, growing addressable user base.
Target buyer: Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job.

Problem severity

22% weight

6.3/10

Problem severity is thin when the buyer pain, customer value, and dream-outcome scores are combined.

Willingness to pay

20% weight

5.5/10

Willingness to pay is weak; the model has a monetization hypothesis, but it must still be proven through paid pilots or explicit pricing objections.

Freemium subscription: free single calculators to acquire users, then a Pro subscription (e.g., $4-8/month or annual) unlocking the full calculator suite, multiple code years, offline mode, and project export; plus optional team/contractor seats and a one-time-purchase desktop/web bundle.

Competitive saturation

18% weight

3.9/10

Competitive room is reduced by 3 recorded alternative(s); the wedge must stay narrow and differentiated.

Recorded alternative: Electrical Calc Elite (NEC Code Calculator)
Competitive score rewards a narrow wedge, not absence of research.

Feasibility

16% weight

6.2/10

Feasibility is thin for a moderate build if the MVP is limited to the first measurable workflow.

Validate willingness-to-pay by offering a $5/month preorder for the full offline app and tracking conversion from the free calculator's users; a target of >5% of repeat users joining the waitlist or preordering signals demand.
Crowded, mature market: established paid apps (Electrical Calc Elite, ElectriCalc Pro, Electrician's Helper) and many free web calculators already cover these calculations, so differentiation and customer acquisition are hard.

Next validation step

Validation sprint

Seven days to a build / kill decision.

Derived from this report's own validation test, channels, offers, and kill criteria. Each day has a threshold, so the week ends in a decision instead of a feeling.

Day 1

Build the buyer list

List 50-100 named working electricians, electrical contractors, apprentices, journeymen, master electricians, and ahj inspectors who need fast, code-grounded calculations on the job. prospects from Community pain posts and Direct outreach — names, not categories.

Threshold: 50+ named, reachable buyers on the list.

Day 2

Join the watering holes

Join and observe Reddit / forums, Launch communities, Review and alternative pages. Collect the exact words buyers use for this pain.

Threshold: 10+ verbatim pain quotes captured.

Day 3

Send first outreach

Send the cold outreach template (below) to 15 buyers from the day-1 list, personalized with one detail each.

Threshold: 15 sent; 3+ replies of any kind.

Day 4

Run buyer interviews

Hold 15-minute calls using the interview script (below). Listen for current workarounds and what they cost.

Threshold: 3+ completed interviews.

Day 5

Run the report's validation test

Stand up a single high-value calculator (conduit fill or voltage drop) as a free web tool with clear NEC article citations and code-year selection, drive traff...

Threshold: Problem resonance: 5+ calls or 10+ detailed replies.

Day 6

Make the smoke offer

Offer "Concierge review or paid template" at $19-$99 to every interviewed buyer. Manual delivery is fine — payment is the signal.

Threshold: 1+ pre-commitment (payment, signed LOI, or scheduled paid pilot).

Day 7

Decide against the kill criteria

Score the week against this report's kill criteria, then take the stated next validation step: Stand up a single high-value calculator (conduit fill or voltage drop) as a free web tool with clear NEC article citations and code-year selection, drive traff...

Threshold: A written build / keep-testing / kill decision.

Pass signal

Pass: thresholds on days 3, 4, and 6 are met — proceed to the next validation step with real buyer language in hand.

Fail signal

Kill or rethink if the week confirms: Fewer than five qualified buyers agree to discuss the workflow after targeted outreach.

A moderate build can work if the MVP stays limited to the first repeated workflow.

Why now

Exceptional

10/10

Demand for electricians is in a structural boom: BLS projects 9% employment growth 2024-2034 (about 81,000 openings per year) while nearly 30% of union electricians near retirement, and electrification (data centers, where electrical work is 45-70% of construction cost, plus EV and solar) is widening the skills gap. A growing share of less-experienced apprentices entering the field need exactly the code-lookup automation a calculator provides, and the unusually large 2023 NEC revision plus the 2026 cycle increase the value of a tool that stays current with the latest adopted code.

Market and money

Business fit and offer ladder.

Revenue potential

$250K-$2M ARR potential if the wedge proves budget urgency and becomes a recurring workflow.

Economics

Price-anchored revenue scenarios.

Derived from this report's "Core offer" offer-ladder stage ($49-$499/month). These are price-anchored scenarios, not market-size claims.

Proof

10 customers

$490-$4,990 MRR

Ten paying customers proves willingness to pay and funds continued validation.

Wedge

50 customers

$2,450-$24,950 MRR

Fifty customers in one niche makes the workflow the default in that circle and feeds referrals.

Vertical leader

250 customers

$12,250-$124,750 MRR

A few hundred accounts in one vertical is a real business before any horizontal expansion.

Break-even

At $49-$499/month, 1 customers cover the stated Local-first MVP budget: $0-$10K before paid acquisition. budget within a month; fewer if they land at the top of the range.

Sizing the buyer universe

Size the buyer universe in one day: count working electricians, electrical contractors, apprentices, journeymen, master electricians, and ahj inspectors who need fast, code-grounded calculations on the job. reachable through the report's channels (directories, associations, communities) until the list stops growing — the test only needs the first 100 names, not a TAM estimate.

Pricing benchmark

Build only if the complaint repeats across interviews, posts, or existing workflow artifacts.

Tooling readiness

6/10

AI-assisted product work and managed infrastructure reduce the first-version cost.

Urgency becomes real only if the current workaround costs time, risk, money, or reputation every week.

Distribution: Reachable buyer language

10/10

The first channel should be whichever source lane already contains the buyer's vocabulary.

Positioning

Market gaps and execution plan.

Underserved segments

Time To Execute

Execution-readiness scorecard.

The score turns the report into bottlenecks, accelerators, and a dated first-month launch plan.

65/100

Needs focused validation

Electric code calculator scores 65/100 for execution readiness. The recommended next step is Stand up a single high-value calculator (conduit fill or voltage drop) as a free web tool with clear NEC article citations and code-year selection, drive traffic from electrician subreddits/forums and trade Facebook groups, and measure return usage plus an email/waitlist gate for a 'Pro suite.' Validate willingness-to-pay by offering a $5/month preorder for the full offline app and tracking conversion from the free calculator's users; a target of >5% of repeat users joining the waitlist or preordering signals demand.

Execution scorecard is generated from report validation, confidence, feasibility, founder fit, and difficulty.

Bottlenecks

Crowded, mature market: established paid apps (Electrical Calc Elite, ElectriCalc Pro, Electrician's Helper) and many free web calculators already cover these calculations, so differentiation and customer acquisition are hard.
Code accuracy and liability: NEC tables and rules are intricate and change every cycle; an incorrect result can cause failed inspections or unsafe installs, demanding rigorous validation, disclaimers ('not a replacement for the code book'), and ongoing maintenance per edition.
NFPA copyright/licensing constraints limit how directly you can reproduce code text and tables, so the product must compute from rules without redistributing protected content.
Willingness-to-pay ceiling: many electricians default to free tools, so converting free users to a recurring subscription against zero-cost alternatives is a real revenue risk.
A broad AI assistant can flatten differentiation unless the wedge is painfully specific.

First milestones

2026-07-08: Frame the wedge

Roast

Promising enough to test, not strong enough to build broadly.

Blind spots

Crowded, mature market: established paid apps (Electrical Calc Elite, ElectriCalc Pro, Electrician's Helper) and many free web calculators already cover these calculations, so differentiation and customer acquisition are hard.
A broad AI assistant can flatten differentiation unless the wedge is painfully specific.
The first release can become a generic dashboard if the job is not named tightly.

What proof would make a skeptical buyer trust it in one screen?
What is the smallest paid version of this idea?

Kill criteria

Fewer than five qualified buyers agree to discuss the workflow after targeted outreach.
No buyer can name a current cost in time, money, risk, or reputation.

Pivot map

If this exact wedge isn't yours, these are adjacent.

Derived deterministically from this report's buyers, vertical language, and business model.

Same problem, different buyer: Budget owner who feels the operational cost of the broken workflow.

The workflow pain in this report is not exclusive to working electricians, electrical contractors, apprentices, journeymen, master electricians, and ahj inspectors who need fast, code-grounded calculations on the job.. Budget owner who feels the operational cost of the broken workflow. faces the same friction with their own budget and urgency.

First test: Re-run day 3 of the sprint (15 outreach messages) against this buyer only, and compare reply rates before changing anything else.

Same workflow, adjacent vertical: Software, AI & Developer Tooling

This report's language already overlaps Software, AI & Developer Tooling (developer teams). The same first-win workflow usually transfers with new vocabulary and one changed integration.

First test: Rewrite the one-line promise for a Software & AI buyer and test it in that vertical's channels before building anything new.

Open that vertical's brief

Same wedge, alternate model: a productized service (fixed-price, done-for-you delivery)

This report monetizes via "Freemium subscription: free single calculators to acquire users, then a Pro subscription (e.g., $4-8/month or annual) unlocking the full calculator suite, multiple code years, offline mode, and project export; plus optional team/contractor seats and a one-time-purchase desktop/web bundle.". Concierge delivery validates willingness to pay before any software exists and earns the workflow knowledge the product needs.

First test: Offer both versions on day 6 of the sprint and let the first pre-commitment choose the model.

One-Line Verdict

Electric code calculator should be tested as a narrow first-win workflow for Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job.. This is not a green light to build the full product. It is a structured prompt to test the buyer, the workflow, and the willingness to pay before committing engineering time.

Problem

The initial hypothesis is that Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job. already has enough recurring friction to justify a narrow tool if it saves time, reduces risk, or improves communication in a visible way.

Who Pays

Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job. is the target buyer. The strongest early customer is the person who owns the consequence when this workflow is late, unclear, or inconsistent. They might pay when the product turns a recurring manual task into a dependable output with source links and a review path.

Evidence Signals

BLS Occupational Outlook Handbook: electricians held about 818,700 jobs in 2024, median wage $62,350 (May 2024), with employment projected to grow 9% from 2024 to 2034 and roughly 81,000 openings per year — a large, growing addressable user base.
The 2023 NEC introduced nine new articles, deleted three, revised seven article titles, and relocated four articles; one expert described it as going ‘through the 2023 Handbook with a paint roller,’ underscoring the complexity buyers must keep up with on a three-year revision cycle.
Electrification demand is acute: industry coverage notes electrical work is 45-70% of data center construction cost and estimates a need for 300,000+ additional electricians for AI-related buildout, pulling many newer workers who lean on calculation aids into the trade.
Multiple commercial calculator apps already exist and sustain paid sales (e.g., Electrical Calc Elite by Calculated Industries supports NEC editions back to 1996), proving electricians will pay for code-grounded calculation tools.

These signals are directional, not proof. The report should move to build only after live buyer conversations confirm that the workflow repeats and that the buyer can describe a concrete cost.

Scorecard

Opportunity: 6/10 (Promising) - Electric code calculator has an editorial confidence score of 58/100 before live buyer validation.
Problem: 5/10 (Promising) - Electricians constantly perform NEC calculations (conduit fill per Chapter 9, ampacity/wire sizing per Table 310.16, voltage drop, box fill per Article 314.16, and load calcs) by flipping through dense, frequently revised code books or generic calculators. The NEC changes every three years and the 2023 edition added nine new articles, deleted three, and revised many titles, so a manual or outdated reference produces errors that cause failed inspections, rework, callbacks, and liability. Existing free web calculators are fragmented across single-purpose pages and lack offline reliability, current-code traceability, and project save/sharing.
Feasibility: 6/10 (Promising) - A moderate build can work if the MVP stays limited to the first repeated workflow.
Why now: 10/10 (Exceptional) - Demand for electricians is in a structural boom: BLS projects 9% employment growth 2024-2034 (about 81,000 openings per year) while nearly 30% of union electricians near retirement, and electrification (data centers, where electrical work is 45-70% of construction cost, plus EV and solar) is widening the skills gap. A growing share of less-experienced apprentices entering the field need exactly the code-lookup automation a calculator provides, and the unusually large 2023 NEC revision plus the 2026 cycle increase the value of a tool that stays current with the latest adopted code.

Validation Score

56/100 - Research. Research is the current validation verdict: problem severity is the strongest signal, while competitive saturation is the main evidence gap to close before scaling the build.

Rubric version: INAV-VALIDATION-2026-06-04

Demand signal: 6/10, weight 24%. Demand looks thin because the report has 4 source-backed signal(s), an editorial confidence of 58/100, and a defined buyer in Electrical trades software and field-reference tools serving residential, commercial, and industrial electrical contractors in the US (and Canada via CEC)..
Problem severity: 6.3/10, weight 22%. Problem severity is thin when the buyer pain, customer value, and dream-outcome scores are combined.
Willingness to pay: 5.5/10, weight 20%. Willingness to pay is weak; the model has a monetization hypothesis, but it must still be proven through paid pilots or explicit pricing objections.
Competitive saturation: 3.9/10, weight 18%. Competitive room is reduced by 3 recorded alternative(s); the wedge must stay narrow and differentiated.
Feasibility: 6.2/10, weight 16%. Feasibility is thin for a moderate build if the MVP is limited to the first measurable workflow.

Next validation step: Stand up a single high-value calculator (conduit fill or voltage drop) as a free web tool with clear NEC article citations and code-year selection, drive traffic from electrician subreddits/forums and trade Facebook groups, and measure return usage plus an email/waitlist gate for a ‘Pro suite.’ Validate willingness-to-pay by offering a $5/month preorder for the full offline app and tracking conversion from the free calculator’s users; a target of >5% of repeat users joining the waitlist or preordering signals demand.

Business Fit

Revenue potential: $250K-$2M ARR potential if the wedge proves budget urgency and becomes a recurring workflow.
Execution difficulty: Execution is moderate; the main constraint is staying narrow enough for a first proof loop.
Go-to-market: Start with manual concierge output, direct outreach, and community proof before paid acquisition.
Founder fit: Best for an AI-assisted solo founder who can interview the buyer and ship a focused first version quickly.

Offer Ladder

Lead magnet: Electric Code Calculator checklist (Free) - Helps Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job. audit the painful workflow before buying software. Goal: Capture qualified leads and learn the buyer’s exact language.
Frontend offer: Concierge review or paid template ($19-$99) - Delivers the first useful output manually before automation is trusted. Goal: Validate urgency, workflow fit, and willingness to pay.
Core offer: Electric code calculator focused SaaS ($49-$499/month) - Turns the recurring manual workflow into a repeatable product loop. Goal: Create the recurring revenue product after the narrow wedge survives tests.
Continuity: Monitoring, benchmarks, and monthly reporting ($99-$1,000/year add-on) - Keeps the buyer engaged with ongoing proof, saved time, or reduced risk. Goal: Increase retention and make the product part of a routine.
Backend offer: Done-with-you setup, agency, or team rollout (Custom) - Adds implementation help, integrations, and workflow migration. Goal: Capture higher-value accounts once the productized wedge is proven.

Economics

Derived from this report’s “Core offer” offer-ladder stage ($49-$499/month). These are price-anchored scenarios, not market-size claims.

Proof (10 customers): $490-$4,990 MRR. Ten paying customers proves willingness to pay and funds continued validation.
Wedge (50 customers): $2,450-$24,950 MRR. Fifty customers in one niche makes the workflow the default in that circle and feeds referrals.
Vertical leader (250 customers): $12,250-$124,750 MRR. A few hundred accounts in one vertical is a real business before any horizontal expansion.
Break-even: At $49-$499/month, 1 customers cover the stated Local-first MVP budget: $0-$10K before paid acquisition. budget within a month; fewer if they land at the top of the range.
Sizing: Size the buyer universe in one day: count working electricians, electrical contractors, apprentices, journeymen, master electricians, and ahj inspectors who need fast, code-grounded calculations on the job. reachable through the report’s channels (directories, associations, communities) until the list stops growing — the test only needs the first 100 names, not a TAM estimate.
Benchmark: 3 adjacent products recorded (2 strong). Position the price against what working electricians, electrical contractors, apprentices, journeymen, master electricians, and ahj inspectors who need fast, code-grounded calculations on the job. already pays in time or tooling, and verify each named alternative’s public pricing during the sprint.

Why Now

Demand visibility: 5/10 - BLS Occupational Outlook Handbook: electricians held about 818,700 jobs in 2024, median wage $62,350 (May 2024), with employment projected to grow 9% from 2024 to 2034 and roughly 81,000 openings per year — a large, growing addressable user base. Build only if the complaint repeats across interviews, posts, or existing workflow artifacts.
Tooling readiness: 6/10 - AI-assisted product work and managed infrastructure reduce the first-version cost. The first release should automate one high-friction step rather than become a broad platform.
Budget clarity: 4/10 - Freemium subscription: free single calculators to acquire users, then a Pro subscription (e.g., $4-8/month or annual) unlocking the full calculator suite, multiple code years, offline mode, and project export; plus optional team/contractor seats and a one-time-purchase desktop/web bundle. Ask for money during validation before building the full workflow.
Competitive window: 8/10 - The wedge is specific enough to test without claiming the whole market. Position around one buyer and one measurable first-win outcome.

Proof Signals

Pain: 5/10 - Repeated workflow friction. BLS Occupational Outlook Handbook: electricians held about 818,700 jobs in 2024, median wage $62,350 (May 2024), with employment projected to grow 9% from 2024 to 2034 and roughly 81,000 openings per year — a large, growing addressable user base.
Money: 4/10 - Budget hypothesis. Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job. is the first group to test because the monetization path is: Freemium subscription: free single calculators to acquire users, then a Pro subscription (e.g., $4-8/month or annual) unlocking the full calculator suite, multiple code years, offline mode, and project export; plus optional team/contractor seats and a one-time-purchase desktop/web bundle.
Urgency: 6/10 - Switching pressure. Urgency becomes real only if the current workaround costs time, risk, money, or reputation every week.
Distribution: 10/10 - Reachable buyer language. The first channel should be whichever source lane already contains the buyer’s vocabulary.

Existing Product Check

strong: Electrical Calc Elite (NEC Code Calculator) - Established paid NEC code calculator from Calculated Industries supporting NEC editions back to 1996, covering wire sizing, conduit, voltage drop, and more — a direct, well-known competitor proving paid demand and setting the differentiation bar.
strong: ElectriCalc Pro Electrical Calculator - Popular electrician calculator app compliant with multiple NEC editions (2023, 2020, 2017 and earlier) for wire sizing, conduit, and related calculations — a direct paid competitor in the same category and price tier.
possible: SparkShift NEC Calculators - A newer workforce platform offering 40+ free NEC web calculators (wire sizing per 310.16, conduit fill per Chapter 9, box fill per 314.16, voltage drop) plus offline iOS/Android tools — a freemium-adjacent competitor that pressures any free-to-paid conversion strategy.

Market Gaps

Underserved Segments

Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job. who still run the workflow in spreadsheets, generic docs, email, or chat threads.
Small teams in Electrical trades software and field-reference tools serving residential, commercial, and industrial electrical contractors in the US (and Canada via CEC). that feel the pain weekly but are too narrow for broad incumbents.
New adopters who need guided proof before committing to a larger platform.

Feature Gaps

A narrow workflow that reaches value without configuration-heavy onboarding.
A buyer-facing proof artifact that shows time saved, risk reduced, or communication improved.
A handoff path from manual concierge service to repeatable software.

Differentiation Levers

Use specificity as the wedge: one buyer, one workflow, one measurable result.
Show proof earlier than broad competitors with before-and-after examples and small pilot data.
Keep implementation lighter than incumbent suites or generic AI assistants.

First move: Post a problem teardown for Electrical trades software and field-reference tools serving residential, commercial, and industrial electrical contractors in the US (and Canada via CEC). and ask how people solve it today.
Launch communities: Validation lane. Launch traction shows whether the promise is legible. First move: Ship a narrow demo and watch which promise gets clicks.
Review and alternative pages: Objection lane. Pricing and alternatives expose buyer objections. First move: Write an alternatives page that owns one narrow use case.

Keyword Intelligence

Keyword signals should be treated as directional. The strongest terms combine Electrical trades software and field-reference tools serving residential, commercial, and industrial electrical contractors in the US (and Canada via CEC)., the buyer workflow, and the first output the product creates.

electric workflow: directional medium; rising with AI adoption; medium competition
code validation: directional low; steady niche demand; low competition

MVP Scope

MVP

A mobile-first (iOS/Android) plus web app bundling the highest-use NEC calculators — conduit fill (EMT/PVC/IMC/RMC), wire/ampacity sizing with temperature derating, voltage drop, box fill, and basic dwelling/service load calc — each citing the specific NEC article/table used, selectable by adopted code year (2017/2020/2023), working fully offline, and letting users save and share per-project calculation sheets. Launch with a free tier (a few core calculators) and a paid Pro tier unlocking all calculators, code-year switching, and project export.

The first version should produce one trusted output, preserve source links, and make human review explicit. Everything else can stay manual: onboarding, unusual edge cases, integrations, templates, and account management.

Risks

Crowded, mature market: established paid apps (Electrical Calc Elite, ElectriCalc Pro, Electrician’s Helper) and many free web calculators already cover these calculations, so differentiation and customer acquisition are hard.
Code accuracy and liability: NEC tables and rules are intricate and change every cycle; an incorrect result can cause failed inspections or unsafe installs, demanding rigorous validation, disclaimers (‘not a replacement for the code book’), and ongoing maintenance per edition.
NFPA copyright/licensing constraints limit how directly you can reproduce code text and tables, so the product must compute from rules without redistributing protected content.
Willingness-to-pay ceiling: many electricians default to free tools, so converting free users to a recurring subscription against zero-cost alternatives is a real revenue risk.
Trying to build a broad platform before the narrow workflow has proof.

Validation Experiments

First Validation Test

Stand up a single high-value calculator (conduit fill or voltage drop) as a free web tool with clear NEC article citations and code-year selection, drive traffic from electrician subreddits/forums and trade Facebook groups, and measure return usage plus an email/waitlist gate for a ‘Pro suite.’ Validate willingness-to-pay by offering a $5/month preorder for the full offline app and tracking conversion from the free calculator’s users; a target of >5% of repeat users joining the waitlist or preordering signals demand.

Additional Tests

Write the one-sentence promise and test it in the strongest channel.
Create the lead magnet and use it to recruit interviews.
Build the smallest demo that proves the first win.

Kill Criteria

Fewer than five qualified buyers agree to discuss the workflow after targeted outreach.
No buyer can name a current cost in time, money, risk, or reputation.
The first demo does not produce a clear next step, paid pilot, or specific objection.

Founder Fit

Score: 8/10. A solo or AI-assisted founder with direct access to Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job..

Advantages

Can talk to the buyer before writing much code.
Can ship a narrow first-win demo quickly.
Can use local-first research artifacts to keep validation moving without a large team.

Gaps

Needs real buyer access, not only desk research.
Needs proof of budget or repeated urgency.
Needs a crisp wedge before broad product work starts.

Avoid If

You cannot reach the buyer directly.
The idea only sounds interesting but does not save time, money, risk, or reputation.
You want to build the full platform before validating the first workflow.

Roast

Promising enough to test, not strong enough to build broadly.

Crowded, mature market: established paid apps (Electrical Calc Elite, ElectriCalc Pro, Electrician’s Helper) and many free web calculators already cover these calculations, so differentiation and customer acquisition are hard.
A broad AI assistant can flatten differentiation unless the wedge is painfully specific.
The first release can become a generic dashboard if the job is not named tightly.

Hard Questions

Who wakes up already trying to solve this?
What do they stop paying for or stop doing when this works?
What proof would make a skeptical buyer trust it in one screen?
What is the smallest paid version of this idea?

De-Risking Moves

Sell a manual pilot before building automation.
Record five exact phrases buyers use to describe the pain.
Cut any feature that does not support the first measurable win.
