What do I do if there is no circuit breaker for outdoor light?
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.
What device is used as a form of safety device in an electrical circuit?
A fuse or circuit breaker will fit this description.
What device protects an electrical circuit?
An example of a circuit protection device is a fuse. Another example is a circuit breaker.
What is Local breaker back up protection?
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.
What circuit protection device can be reset after it opens?
A circuit breaker is an overcurrent device that can be reset after it has opened.
A GFCI device in a breaker is intended to?
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.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
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.
What device is used for turning a circuit on or off?
Circuit breaker or switch
Is a circuit breaker a resistor?
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.
What safety device is fitted to ensure a circuit breaker can not be racked out when closed?
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.
A device that protects a circuit from current overload is called what?
Fuse, Circuit breaker
What is the Simplest protective device for an electric current?
A fuse is the simplest protective device for over current in an electric circuit.
