ElecCalc Field Pro

Conduit bend, pipe fill, box fill & voltage drop calculators for electricians — built for NEC and Canadian OEC, plus an AI code assistant. Fast, offline, jobsite-ready.

ElecCalc Field Pro puts the calculators journeyman and apprentice electricians actually use on the job — conduit bending, pipe fill, box fill, voltage drop, and phase color reference — in one fast, offline-first app built for the field, not the office.

No account, no sign-up, no internet connection required for any calculator. Open it on a rooftop, in a panel room, or anywhere else signal doesn't reach, and get an answer in seconds.

FEATURES

Bend Calc — Offsets, saddles, stub-ups, and rolling offsets, calculated instantly for any conduit size and bend angle.

Pipe Fill — NEC / Canadian OEC conduit fill calculator. Enter conductor count and size, get a straight fill percentage and code compliance check.

Box Fill — NEC 314.16 box fill calculator. Stop doing this math by hand or guessing — get an exact cubic-inch count.

Volt Drop — NEC 210.19 / 215.2 voltage drop calculator for sizing conductors on long runs.

Phase Colors — NEC and Canadian OEC wire color reference with a built-in pull checklist, so a crew stays consistent across a job.

Time & Material — Track labor hours, materials, and job totals right from the field, without a separate app or a paper ticket.

AI Code Assistant — Ask plain-language NEC / OEC code questions and get cited answers referencing the actual code sections. (Subscription feature — see below. Always verify safety-critical answers against the current code book; this tool is a reference aid, not a substitute for the NEC/OEC or a licensed inspector's judgment.)

Built by an electrician-adjacent developer who got tired of doing this math by hand on every job.
