Working electricians, electrical contractors, apprentices, journeymen, master electricians, and AHJ inspectors who need fast, code-grounded calculations on the job.
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every three years and the 2023 edition added nine new articles, deleted three, and revised many titles, so a manual or outdated reference produces errors that cause failed inspections, rework, callbacks, and liability.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.

- 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.
- Budget
- 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.
Budget owner who feels the operational cost of the broken workflow.
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.

Hands-on operator willing to pilot a narrow tool before a full rollout.
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.
