ElecCalc Field Pro

ElecCalc Field Pro puts the calculators journeyman and apprentice electricians actually use on the job — conduit bending, pipe fill, box fill, voltage drop, load calc / service sizing, and phase color reference — in one fast, offline-first app built for the field, not the office. Built for both NEC and CEC/OEC codes.

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.
