Calculate voltage drop, minimum conductor size, maximum run length, conductor resistance and power losses from transparent physical formulas.
Choose IEC or AWG/KCMIL conductors, enter current or load power, include power factor, cable reactance and parallel runs, compare adjacent sizes and estimate annual energy cost.
Save calculations into projects, reopen them with every input restored and share results from the job site.
The app works offline and does not reproduce code ampacity tables or recommend circuit breaker ratings.
Calculate wire size, voltage drop, resistance and cable energy losses offline.
