Electrician Calculator Toolkit

Eight electrician calculators built for the job site: fast, accurate, and fully offline. Every result shows the code table it came from, so you can check it against the book or explain it to the inspector. VOLTAGE DROP Single-phase, three-phase or DC. Copper or aluminum, #14 AWG to 750 kcmil, feet or meters, parallel sets. See the drop in volts and percent, the voltage at the load, and the smallest conductor that stays under 3%. WIRE SIZE (AMPACITY) Enter the load, mark it continuous, pick 60/75/90°C terminations and the material. The app applies the 125% rule, the ambient-temperature correction and the adjustment for more than three current-carrying conductors, respects the small-conductor limits, and shows the adjusted ampacity of every size around the answer. CONDUIT FILL Add any mix of conductor sizes and insulation types (THHN/THWN, XHHW, THW) and get the minimum trade size for…
