yes when combined with a suitable protective relay
If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.
A fuse or circuit breaker will fit this description.
An example of a circuit protection device is a fuse. Another example is a circuit breaker.
Breaker is a protective device that cuts off the electrical circuit in case of fault. The additional breaker can be provided as backup protection locally, which is known as local back up.
A circuit breaker is an overcurrent device that can be reset after it has opened.
A GFCI device in a breaker is intended to trip the breaker open when a ground fault is sensed in the circuit that the breaker is protecting.
Circuit breaker or switch
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
A remote racking device is the name of a safety device that is fitted to ensure a circuit breaker cannot be racked out when closed.
To determine what is tripping your circuit breaker, you can unplug all devices on that circuit and then plug them back in one by one to identify the culprit. If the breaker trips when a specific device is plugged in, that device may be causing the issue.
Fuse, Circuit breaker
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
