Voltage Rating. The voltage rating of the overcurrent protective device must be at least equal to or greater than the circuit voltage. The overcurrent protective device rating can be higher than the system voltage but never lower. For instance, a 600V fuse or circuit breaker can be used in a 208V circuit.
