The most common reasons for AC failure assuming the power is on in the rest of the building are Transformer is blown due to power surge Circuit breaker that controls the outlet needs reset Outlet is a GFCI or GFI that has the circuit breaker built into the outlet itself and needs reset Transformer become unplugged from the outlet.
A multimeter is a versatile device used to check voltage in electrical circuits as well as determining whether a circuit is using alternate current AC or direct current DC . You can use a multimeter to test the breakers in your circuit box and
Circuit breakers prevent this by automatically shutting off electricity to circuits when too much electricity is passing through them. For example most furnace breakers are 15 amp breakers. If more than 15 amps of electricity flows through it the breaker will trip and turn off electricity to that circuit to prevent the wires from overheating.
