The National Electrical Code® (NEC) was the first to reference it, and today continues to set the standards for the electrical industry. Following a uniform color code makes it easier to assess electrical wiring, and ensure safety among licensed professionals and homeowners alike.

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.

Wire color codes or cable color code charts for both AC and DC are classified based on national standards for each region. You may find different colors in different countries, so that’s why we need to check it by ourselves or consult a professional.
