Have you ever gone to plug something in, only to be presented with a confusing mess of different colored electrical wires? With so many colors, it can be hard to keep them straight. The truth is, each color of wire denotes a different purpose, and learning which one goes where can save you a lot of time and energy. Let’s review the electrical wire colors for plugs and why they’re important.
The first thing to understand about plugs is that there are three basic wire colors: black, white, and green. The black wire is usually the “hot” wire and carries the power. The white wire is usually the neutral wire and also carries power, but at a lower voltage. The green wire is the ground wire and provides a safe path for electricity to flow away from the appliance. It’s important to make sure that these wire colors are properly connected or else an electric shock could occur.
The other wires you may see in a plug are usually either brown or blue. Brown is the alternate hot wire while blue is the alternate neutral wire. In some cases, such as an outlet with two hot wires, you may need to use the brown and black wires instead of the white and black. Furthermore, there may be bare copper wires present in the plug which should be connected to the ground.
In conclusion, different colored electrical wires serve different purposes in a plug. Black and white wires are the standard for carrying power, while green is used as the ground wire. In cases where more than one hot wire is needed, brown and blue wires may also be present. Knowing which color of wire goes where is essential in preventing dangerous electric shocks.
