In the case of a 110V home electrical circuit, the colors indicate the function of each wire. In the United States, AC Wires are color-coded for safety.

The ground wire is there to remove any extra power, and sends a signal back to the breaker, stopping the main power source. The electricity then flows back through the neutral wire to complete the circuit. The electricity will flow through the hot wire into the device you wish to power, or to a receptacle in your home. This is important because a single circuit breaker can only stand so much power and is designed to trip if overloaded with power.Ī continuous electrical circuit consists of three wires a hot wire, a neutral wire, and a ground wire. As explained in a previous post, when you multiply Voltage by Current it produces Watts. The transformers in your neighborhoods transform power voltages into 120V of power required for your house. The main circuit in your home is supplied by electricity from outside the home. Your home uses AC power to run every electrical item in your home or building. There is no reason to risk the safety of yourself and your home. It is essential you don’t work on anything electrical in your home or other buildings if you are unsure what you are doing. A basic understanding of AC power is essential if you are a homeowner, want or need to change out any basic electrical in your home, or want to know how the power in your home works. AC is the type of electricity used for homes and other buildings.
