Electrical Wiring Color Codes for AC & DC NEC & IEC
Wire Color Codes: Understanding how different wire colors signify functions such as hot, neutral,. In order to identify electrical wires based on their color codes, one can refer to a wire color code chart or consult the guidelines provided by the National Electrical Code (NEC). While the NEC offers guidance for some conductor colors, others.

First on the electrical wire color code is black. Black wires are "hot" wires. They carry current from the home's electrical panel to the light, appliance or other device that needs electricity. There's no NEC requirement that hot wires be black or any other color, but black is the go-to for residential use.

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. Keep in mind that not every country has all the wire color codes recorded in a document.

Infographic: What Do Electrical Wire Colors Mean? Black Electrical Wires This color of wire is used to transfer power to switches and outlets in all types of circuits. Also, black wires are often used as switch legs in circuits, which is the connection linking a switch to the electrical load. Consider all black wires to be live at all times.
