Common questions
How many amps is a 25 kVA single phase transformer
About 104 amps at 240 volts, and about 208 amps at 120 volts. Single phase current is kVA times 1000 divided by the voltage. There is no square root of three in a single phase calculation, which is the most common mistake people make with this figure.
What are the dimensions of a 25 kVA single phase pad mounted transformer
Around 30 x 32 x 38 inches and about 470 lb. Manufacturers vary, so confirm against the approval drawing before the pad is poured. The pad itself needs to be larger than the cabinet, and clearances in front of the doors are set by the utility.
