Standard House Wiring Colors

By | August 3, 2022



When it comes to standard house wiring, the colors of the wires that are used can vary from one location to another. However, there are some basic colors that are generally accepted as being the standard for residential wiring. Knowing what these colors mean can help you better understand the wiring in your home so that you can better identify any problems that might arise.

The most common color of wire used in house wiring is white. This color is typically used for neutral and can be connected to either the ground or hot terminals in a circuit. It's important to note that the white wire should never be used as a hot wire, as this could lead to a risk of electric shock. If you're dealing with a three-wire system, you'll also find that black and red wires are used. The black wire is typically used as the hot feeder, while the red wire is often used as the secondary hot wire or the switched hot wire in a light circuit.

Finally, green or bare copper are the standard colors used for the ground wires. You'll usually find the green wires attached to devices such as lights and receptacles, while the bare copper is typically used for ground rods or other grounding material. It's important to remember that any of these colors should never be used as a hot wire, as this could lead to an electric shock if a person were to come into contact with them.

By familiarizing yourself with these standard house wiring colors, you can better understand the wiring in your home and be better able to spot any issues that may arise. Safety is paramount when it comes to electricity, so being aware of the colors used in your house wiring is a great way to ensure your home remains secure.
