## ElectricianCalc NEC Calculator Description
The electrical calculator that gives you NEC-compliant numbers in seconds — voltage drop, wire size, conduit fill, ampacity, box fill — all offline.

Stop flipping through the codebook on a ladder. ElectricianCalc gives you the wire size, voltage drop, conduit fill, and ampacity numbers an inspector signs off on — all referenced to current NEC tables, all available offline.

• Conduit Fill — EMT, IMC, RMC, PVC; per NEC Chapter 9
• Ampacity — THHN, NM, MC, SE; by ambient and bundling
• Ohm's Law — V/I/R/P with unit toggling
• Power / kVA — three phase, line/phase voltage, power factor
• Motor FLA + OCPD — full-load amps and overcurrent protection per NEC 430
• Box Fill — NEC 314.16 by conductor count and size
• Service Calc — load calc preview for residential
