An electric circuit overloads when the current becomes greater than the circuit's design capacity can withstand. Circuit overloads can also be caused by loose or corroded wires and connections.

    How do you read a circuit breaker panel diagram?

    A circuit breaker panel diagram provides the breaker number and reference notes about a specific breaker to the number in the service panel.

    Why does my air conditioner keep blowing fuses?

    A:

    According to About.com, if your air conditioner keeps blowing fuses or tripping circuit breakers, it is because the appliance is trying to draw more current than the fuse or breaker will allow. This can result from a window-mounted air conditioner being plugged into a circuit that is insufficient for its needs, or it could indicate that the air conditioner needs servicing.
