They are modelled based on code produced by national or international standards organizations.

This standard varies for each region or country. Not only that, the temperature, exposure, moisture, and chemical level are planned carefully.Įlectrical wiring standard and electrical wiring installation are made with the purpose of the best safety for people and devices. The types of the wire and its size are strictly classified to the operating voltage and current capability. We must follow the safety standards and installation practice. The devices can be electronic boards, switches, sockets, and room lighting. Electrical WiringĮlectrical wiring is an installation of the electric devices and cables. Knowing the meaning of the color will keep us and our electrical system safe.īefore we start learning about wiring color code, let us understand what electrical wiring is a bit first. We need to know what is the specific purpose for each color before touching it (you better don’t touch or plug-unplug the cable unless you know what is the meaning of its color). Why do we use different colors for cables? No more and no less to differentiate the cable standardization.Ī wire colored in black is different from a cable colored in brown, orange, red, or green. If you have opened a light switch box or an electrical outlet, you might have encountered various confusing colored cables.įor those of you, who haven’t learned about it, let me explain it to you briefly. Especially for electricians, electrical engineers, technicians, and even regular people. Wire color code is a crucial thing to be noted. When it comes to this, we need to use local custom or “alternative” colors. Keep in mind that not every country has all the wire color codes recorded in a document. You may find different colors in different countries, so that’s why we need to check it by ourselves or consult a professional. Wire color codes or cable color code charts for both AC and DC are classified based on national standards for each region.
