Electric wiring calculator

A single-sided calculator to rapidly determine the voltage drop in cables and to give the required cable size to meet specified maximum losses.
The length of circuit is simply set to the current and the cable size read opposite the allowable voltage drop.
A separate section finds the current for either single or three phase from the kW required and the supply voltage.
