“White or gray indicates a neutral wire,” Dawson says. A neutral wire returns electricity from the hot wire back to a grounded portion of the home’s electrical panel to complete the circuit. Without it, the electrical current couldn’t circulate and the live wire couldn’t provide usable power.
Recognize that the black wire is the positive one, the white wire is the negative one, and the green wire is the ground. You may see a copper wire instead of a green wire for the ground.
Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
Red and Black are connected to the switches if the White is used for neutral. The White is often referred to as Common, but the colored wires are also used as hot wires.
A white neutral wire usually connects to a silver-colored terminal or white wire lead. A green or bare ground wire almost always makes a ground connection—to a ground screw on a device, electrical box, or appliance case or to a green wire lead.
The power wire that is grounded is called the “neutral” wire because it is not dangerous with respect to exposed metal parts or plumbing. The “hot” wire gets its name because it is dangerous. The grounding of the neutral wire is not related to the operation of electrical equipment but is required for reasons of safety.
