How to convert 75 kVA to amps

On a three-phase system, amps = kVA × 1,000 ÷ (1.732 × volts): 75 kVA × 1,000 ÷ (1.732 × 208 V) = 208.18 A per line. On single phase, amps = kVA × 1,000 ÷ volts: 75 kVA × 1,000 ÷ 240 V = 312.5 A.

The breaker column assumes a continuous load, sized at 125% of the current, and rounds up to the next standard breaker. Transformers and generators have their own protection rules; follow the nameplate.
