## How do I know how many kVA I need?

Calculate power rating in kilovolts-amperes, or “KVA,” when you know voltage and current rating. Use the formula: P(KVA) = VA/1000 where P(KVA) is power in KVA, V is voltage and A is current in amperes. For example, if V is 120 volts and A is 10 amperes, P(KVA) = VA/1000 = (120)(10)/1000 = 1.2 KVA.
