what color is house wiring - IOT Wiring Diagram

Electrical wiring plays a critical role in the structure and safety of any home. The electrical wires inside a house are responsible for transferring energy from the main electricity source to outlets and other devices. It’s important that the correct type of wire is used for each circuit, but it’s also equally as important to select the proper color.

Most electrical wires come in distinct colors for easy identification and selection. Considering the variety of appliances, switches and outlets, there’s no standard hue for each wire, but rather, a specific color code that is used by professionals for the most common types.

For instance, nonmetallic sheathed cable (NM) is the type of wiring most commonly used in homes. The color-coding system for this type of wiring begins with black and white; black is the hot wire which conveys electricity from the power source to the device to be operated, while white is the neutral wire carrying electricity back to the power source. Red and blue are additional colors, typically used to interconnect rooms on a single circuit. Green and bare copper are also used and refer to grounding. With these particular colors, electricians can easily determine the purpose of each wire before beginning any installation. In short, by following the prescribed color code, homeowners can feel confident that any electrical project is being conducted properly.
