About our electrical calculators

Electrical sizing is the one area where a wrong estimate is a safety issue rather than a budget issue. Undersized cable overheats; an undersized inverter dies early. These calculators follow standard Indian practice for load calculation, derating and voltage drop, and show the working so an electrician can verify it.
