Does it say a circuit ampacity of 54 amps? You will not find a circuit breaker in 54 amps.

The design of this appliance Branch Circuit , i.e. , the ampacity of the conductors and the rating of the circuit-breaker, is predicated on the connected load as expressed in kilowatts and voltage.

We need to know the exact rating in both volts and watts / kilowatts.
