The world of electrical wiring can be a confusing one, especially if you are new to the process. To make things easier, wires are often colored with different shades to indicate their function. However, there are five core colors of wire that you should know before starting any wiring project.
The five core colors in the world of wiring are black, white, red,green and blue. Black is most commonly used for hot wires, meaning that it carries current from the power source to the device or outlet. White is used for neutral wires, which return current back to the source. Red is often used as an additional hot wire, particularly in three-way switches and outlets. Green is used as a ground wire, providing a path for electricity to flow to ground in the event of an overload. Lastly, blue is used as a switched wire, carrying electricity between outlets, switches, and other devices when they are turned off and on.
It is important to note that the colors may vary depending on the type of system being used. Always research the specific wiring system you are working on for the accurate colors before beginning your project. Knowing these five basic wire colors and understanding their function is the first step to successful wiring. Once you are confident in these core colors, you can move forward in your wiring project with confidence.
