Engineers will often provide the kVA sizes of transformers or circuits.

With the calculator below, you can plug in your kVA and system voltage to determine your system amperage. Our calculator will also provide meter suggestions based on your system requirements. 




Line to Line Voltage (208 V, 480 V)

A=1000 x kVA / √(3 × VL-L)

Line to Neutral Voltage (120 V, 277 V)

A=1000 x kVA / (3 × VL-N
