Staying Current

Electricity doesn’t do us much good if a bunch of errant electrons constantly change orchestras from one conductor to another. We want our electrons to move in a reasonably orderly fashion so they can do our bidding when we turn on the lights. A flow of electricity is called a current, and it’s carried into our homes through wiring from local electric utility companies. New electrical systems have the following three wires coming into your house:
➤ Two black or “hot” wires that carry the current to your service panel
➤ One bare neutral wire for carrying the current back to the power source and to ground An electrical current has a couple of different options, depending on your application.
