## Description

Voltage drop, wire sizing, conduit fill, box fill, ampacity and more —
every electrical calculation the trade needs, 100% offline. Lifetime
purchase available.

Tired of flipping through code books on the job? WireSize turns conductor
and circuit questions into instant, accurate answers.

Here's how it works: pick a calculator, enter your numbers, and read the
result. Done. No accounts. No uploads. No tracking. Every calculation runs
entirely on your iPhone.

Whether you're sizing a feeder, checking a panel install, or studying for a
license exam, WireSize is built to be the fastest way to get a number you
can trust.

Start with voltage drop in volts and percentage, for single-phase and
three-phase circuits. Reverse it to find the minimum wire gauge for a target
drop, or the longest run a gauge will allow. Check conductor ampacity with
ambient-temperature and conductor-count derating, capped at the terminal
rating. Size conduit fill for EMT, IMC, RMC, PVC and more — get a pass or
fail instantly, or the smallest conduit that works. Calculate box fill
volume for conductors, devices, clamps and grounds. Lay out conduit bends
with offset, saddle and stub-up math.

It goes further: circuit breaker and overcurrent sizing, equipment grounding
conductor sizing, an Ohm's Law power wheel, single and three-phase power,
kVA to amps, motor full-load current, transformer sizing, power-factor
correction, AWG to mm2 conversion, resistor color codes and NEMA receptacle
references.

Every calculation is built on published electrical standards and verified
against known reference values. Save any result, organize it by job site,
and share it as a PDF for documentation or inspection prep.

No ads. No data collection. No internet required. Just the calculations,
fast.
