How an Electrical System Works

Receptacles, commonly referred as outlets, are used to provide individual plug in points for power distribution. The housing market most frequently uses 125-volt, 15 and 20-amp receptacles for general household equipment. For appliances like 250-volt window air-conditioning units, a 250-volt, 30-amp outlet is required.

Hopefully, having learned the basic parts of the electrical system will be useful to you in the future. Knowing how everything flows from start to finish helps in tracking down electrical problems that might arise.
