The world of electricity and wiring can be a complex one. Different wires are designated for different purposes, and they come in different colors to indicate their function. To the novice electrician, this can be confusing — what do each of these colors mean? Before you start any project that involves electrical wiring, it’s important to understand the various types and colors of wires.
Different colors of electrical wire indicate different levels of voltage as well as function. Red and black are the most common colors used in many residential projects like outlets and switches. These are usually hot wires, which carry the highest amounts of current. Green and white are used for ground wires and are generally bare or wrapped in green insulation. Lastly, yellow and blue are usually found in the same circuits as red and black, and are considered traveler wires, typically carrying shorter runs between switches and outlets.
Understanding the various colors of electrical wires is essential when dealing with electricity. To ensure safety, always check with your local building codes before starting a project and make sure you have the right tools to do the job. Working with electricity is not something to take lightly, so taking the time to study the basic concepts of wiring and the different colors of electrical wires can help ensure that your projects are completed safely and correctly.
