Dec 17, 2024 · While the National Electrical Code (NEC) provides guidance for some conductor colors, on others the code book is silent. However, that doesn’t mean electricians haven’t developed a system over the years. Here, we’ll walk through the electrical wire colors you’re likely to see in your home.

Wiring color codes vary by region and are designed to meet local standards and regulations for AC (Alternating Current) single-phase, AC three-phase, and DC (Direct Current) systems. Notable standards include: The NEC (National Electrical Code) in the United States. The CEC (Canadian Electrical Code) in Canada.
