About this app

BaseCalc Electric Calculator is an NEC-aware electrician calculator for job-site field math, worksheets, materials, and saved calculation history. Run voltage drop, wire size, conduit fill, service load, breaker, grounding, EV charger, generator, and other electrical calculator checks on site, then save the result for the job.

18 CALCULATORS FOR DAILY FIELD WORK
- Ohm's Law: solve voltage, current, resistance, and power from any two known values.
- Voltage Drop: single-phase or three-phase, copper or aluminum, with a 3% target check.
- Wire Size: minimum conductor sizing based on NEC 310.16 ampacity with temperature and conductor-count adjustment.
- Conduit Fill and Conduit Size: fill percentage and first raceway size that passes.
- Box Fill: required box volume per NEC 314.16.
- Conduit Bend and Bend Layout: offset bend marks, rolling offsets, saddles, and layout guidance.
- Service Load: dwelling service/load sizing guide based on NEC 220 concepts.
- Breaker + Wire: continuous-load OCPD and conductor guidance.
- Grounding: EGC and GEC starting-point sizing.
- Motor Circuit: FLC, conductor ampacity, overload, and short-circuit/ground-fault guides.
- Pull Box: straight, angle, and U-pull box dimension guide.
- Derating: temperature correction and current-carrying conductor adjustment.
- EV Charger, Generator, Transformer, and Power calculators for common field checks.

EVERY RESULT IS EXPLAINED
