Non-Operational Electrical Outlets
There are some reasons why an electrical outlet doesn’t work, they can be a circuit breaker has tripped, a ground fault circuit interrupter on an outlet has tripped or an outlet has burned out. In addition, if an outlet is old, it may stop working for many reasons, for example, a wiring becomes loose. Some outlets can be switched on and off, so this kind of outlet may not be working because it is turned off.
To find out if an outlet doesn’t work because a circuit breaker has tripped, it’s better to inspect via an electric panel. All the knobs on the panel may be in the correct position, but a circuit breaker for the outlet may still be tipped. Flip the knobs off and on to reset them for sure. If this fixes the problem but the circuit breaker trips again, unplug some devices, because the electrical system is overloaded.
