Common Electrical Wires and What Their Colors Mean

Are you wondering what all the different colors of your electrical wires mean?  Do you find yourself wondering how to match up the right electrical wire with its correct plug?  Electrical work can be complicated, especially if you have no idea where to start.  One of the most basic ways to start to understand the electric in your home is to know what the different colors of the wires truly mean.  As electricians in Winter Park, FL, we can help you with your electrical needs when you are confused.  These are a few of the common electrical wires and what each of the colors indicates.

Black Wires

Black wires are often always the wires that are live, so you will want to take caution when you are handling these wires.  These are the wires that are sending electrical signals to outlets and powering light switches.  When you handle these wires, you should prepare yourself to feel a warmth since they are most likely live.

Red Wires

These are the types of wires that power large appliances, which means they are handling a large amount of energy at one time.  These are also used as switch legs in circuits, which connect large appliances to the black, live wires.  It is also likely that you will see red wires in smoke detectors, which also means that they are live wires.  Anytime you are dealing with either red or black wires, you should prepare to feel a hot wire.

Blue and Yellow Wires

Blue and yellow wires carry electrical power, but they are more likely to be used in lights that are controlled by certain light switches.  You may see yellow wires in places like ceiling fans or ceiling lights.  Blue wires are most frequently located in three or four-way switches, like those used in the entryway of your home or those powering multiple lights from the same switch plate.

Gray and White Wires

These wires are the more neutral wires that are grounded to a neutral bus bar or used to power black wires.  A bus bar is a metal plate that will safely distribute the electrical current throughout your system to avoid overloading or blowing a fuse or a circuit.  White and gray wires are often interchangeable, neutral wires.  However, you should still take caution when you are working with them if these are hot wires at the time.  These wires can still carry a current, especially when you are experiencing electrical difficulties.


These are some of the most common electrical wires that you will encounter in your home.  Understanding the basic colors and functions of the electrical wires is the first step to knowing how to identify and fix any problems.  If you are experiencing difficulties with your electric, contact our professional electricians in Winter Park, FL to schedule an inspection today.
