Reset a circuit breaker
If you lose electrical power, first check that it is not a problem from the electrical company by checking if there is power in the other houses in the neighborhood.
If only the house has lost power, you can reset it on the circuit breaker. The main panel is located in the cellar just under the passageway (there is a smaller one in the kitchen near the ceiling) . Note: there should be a flashlight on top of the main electrical panel.
The circuit breakers provide protection for each of the electrical circuits by stopping the flow of current if an overload or fault occurs.
Then check the main breaker – white box in left picture. If there is no issues with the main breaker, it should be like in the picture. Otherwise you may need to reset it by pressing the grey button.
A circuit breaker which has been tripped will usually be in the "OFF" position, like in the picture on the right. However, sometimes the switch will not look like it has tripped and may appear as though it is in the "ON" position. If none of the breakers appear to be tripped, gently wiggle each one, the tripped breaker will usually feel looser than the other switches.
Locate the tripped circuit breaker and reset it by pushing it all the way to the "OFF" position and then back to the "ON" position. Often when you cannot reset the circuit breaker, it is because it must be turned all the way to the "OFF" position first.
If the circuit breaker trips again before you have turned anything on or plugged anything in, the breaker itself may need to be replaced.
If the circuit breaker trips after plugging in or turning on a device, that device may have a short or may be placing too much of a load on the circuit.
