Does the job quick and precise

Perfect for Solar wire sizing

Was blind but now I see long ago mistakes thanks author of Solar independent utility systems manual

Voltage Drop Calculator

Quick and easy, with plenty of variables.

Lack of features

Does not support Copper vs Aluminium wire, or proper metric sizes, only equivalent wire gauge.

Response from developer

The App supports wire sizes in mm, inch, AWG. The types of wires supported are copper , Aluminium, carbon steel, electrical steel, nichrome etc

Needs work

I put in information for a sample 20 amp circuit. The answer I got was 14 AWG wire with a 20 amp breaker and a 12 AWG equipment ground. The NEC requires a 15 amp breaker for 14 AWG wire.
