Electrical outlets are used to power appliances such as microwaves.
In all homes, office buildings and factories, standard electrical outlets can be found. These outlets, also known as receptacles or plugs, serve to provide ready-to-use electricity to everyone who needs it. These outlets provide power for everyday items like light bulbs, vacuum cleaners, toasters, microwaves, radios, TVs, and stereo equipment.
While the outlet provides electricity and is easily visible to the naked eye, there is a lot going on behind the scenes, or on the walls in this case, to get electricity to the outlet. Electrical wiring travels from the electrical panel to the outlet, with possible stops at other outlets or lighting devices along the way. For an outlet to work, the hot wire (usually a black or blue wire) will leave the panel and carry power to the outlet, while a second wire, the neutral wire (usually a white wire) returns power from the outlet to the outlet. electric panel. In fact, the energy is taken to the electrical device (an outlet, in this case) and then circulated back to the panel. This is how the term “electrical” came about. Sometimes a third wire is present. This wire (usually green in color) serves as a ground wire.

Many municipalities have electrical codes requiring electrical wiring to be housed in tubes. This is by far the safest way to route electrical wiring and ensure proper grounding. Other forms of housing for electrical wiring are BX (a flexible aluminum coil) and romex (a rubber insulator).
In many older homes, two pin outs are the norm. Modern homes contain three pin outputs, allowing hot, neutral, and ground to be taken to the output. In bathrooms, near kitchen sinks and in garages, you can find GFI containers. GFI stands for Ground Fault Interrupter. These outlets, now required in many states, are extremely sensitive and are installed, or should be installed, anywhere there is water nearby. An outlet like this can save lives, as it will trip (turn off) much like a circuit breaker, if it detects more energy entering the hot wire than exiting through the neutral wire.

For example, if a radio falls into the bathtub while you are showering, you will have some problems, to say the least. With a standard two or three prong receptacle, the energy would continue to flow through the water and through you. Most likely, you would be electrocuted. If, however, that radio was plugged into a GFI receptacle, the receptacle would sense the lack of electricity going back to go through neutral (since it was passing you instead) and trip, thus eliminating power to the radio and potentially saving your life.
