[1] Requires 208-240 Vac to reach full 1.5 kW power output. Optionally, 120 Vac can be used with a derated 1.2 kW power output.

[2] Duty Rating is calculated with: ((Watts * 102%) / Efficiency%) / (Vac – 10%) / PowerFactor. Breaker Rating is calculated with: (Duty Amps / 80%). The Breaker Rating is a minimum requirement. Choose the equivalent or next higher standard breaker rating. The AC wiring must be rated for at least the same current as the breaker. Wire per local codes.
