A circuit breaker’s primary job is to protect the wire, not the device. You should choose a breaker size that is:
Note: If you use a breaker that is too large for the wire, the wire could melt or start a fire before the breaker ever trips.
- Above the maximum continuous current the device draws.
- Below the maximum current-carrying capacity (ampacity) of the wire used in that circuit.
Note: If you use a breaker that is too large for the wire, the wire could melt or start a fire before the breaker ever trips.
