FieldVolt Electrical

FieldVolt — Electrical Calculator for Electricians

Electrical calculator built for real work in the field — fast, accurate, and easy to use when it matters.

Pipe Bending Calculator
Offsets, 3-bend saddles, 4-bend saddles, rolled offsets, back-to-back 90s, and parallel offsets.
Get precise mark locations based on rise, distance, and bend angle — no guessing, no wasted bends.

Conduit Fill Calculator (NEC)
Instant conduit fill calculations using NEC guidelines.
Mix wire sizes and insulation types and get a clear pass/fail with the smallest conduit that fits.

Ampacity Calculator (NEC 310.16)
Size conductors with confidence.
Includes ambient temperature correction and current-carrying conductor derating built in.

Voltage Drop Calculator
Single-phase and three-phase voltage drop calculations with support for parallel sets.
Automatically suggests a larger wire size when exceeding the 3% recommendation.

Box Fill Calculator (NEC 314.16)
Accurate box fill with support for mixed conductors, devices, grounds, and internal clamps.

Built for Electricians
Built in the field by an electrician who got tired of slow, clunky tools that don’t match how work actually gets done.
