When the lights go out in one or more rooms or in a series of electrical outlets the culprit is sometimes a circuit breaker or a fuse has blown.
Fuse box circuit breaker tripped.
Twist the set of wires together at the receptacle box and check the wires at the panel box end with the continuity checker on your voltage meter.
To reset a tripped circuit breaker turn off the breaker by moving the switch or handle to the off position and then turn it back on.
Check each appliance for overheating when you unplug it.
If there were no circuit breaker trips then house fires would have been quite a common issue.
They provide more accurate protection than traditional wire fuses.
Disconnect the wire from the circuit breaker and the receptacle.
The circuit breaker trips when too much electricity flows through it or when it cannot handle the excess current load.
To test for circuit overload the next time the breaker trips go to the electrical panel and turn off all the switches in the affected area and unplug all appliances lamps and other devices.
In the case of circuit breakers the immediate answer is to find the breaker that has tripped and reset the lever to the on position.
Fuse switches or circuit breakers switches that trip to protect the appliances in your home if there s a fault in the circuit.
Rcds residual current devices switches that will trip and turn off the electricity if the circuit they manage is considered dangerous.
If your fuse switch has tripped after you ve been using a lot of appliances in one room you ve likely overloaded the circuit.
Switch the main circuit breaker to the off position.
When an appliance or light fixture suddenly goes dead it is very likely that a circuit breaker has tripped and interrupted the power flowing to the electrical circuit.
When a fuse blows a metal filament inside the fuse has burned through meaning that you ll need to replace the fuse with a new one.
No continuity indicates a break in the wire.
For safety it s a good idea to stand back or to the side of the panel for safety just in case any sparks come from the breaker when it s moved or to wear safety goggles when resetting a circuit breaker.
However in some cases the breaker or fuse may seem fine and even if you reset the circuit breaker the circuit is still dead.
If it stays on plug the appliances back in one by one until it trips again and service or discard the appliance that makes it trip.
This means that the flow of electricity is cut off to keep your circuits from overheating or causing more damage.
