By | January 5, 2023



The three-phase wire color code European standard has been adopted by many countries for the purpose of safe wiring and accurate electrical identification. It is widely used in industrial, commercial and domestic settings to ensure safety and limit the risk of electric shocks and fire hazards. The three-phase wire color code consists of a variety of colors which indicate the phase, line and neutral in an electrical system. Knowing the European three-phase wire color code is essential for electricians to safely identify and install wiring systems.

The European three-phase wire color code is an important safety measure that is designed to prevent electric shocks and other accidents in electrical installations. This color code system ensures that when a power cable is connected to an electrical appliance, it will be correctly wired and grounded. Understanding the European three-phase wire color code can help both electricians and homeowners to correctly identify the wiring in their homes, businesses or industrial settings. In this article, we’ll discuss how the European three-phase wire color code works, the different colors it uses and the importance of understanding it.

The European three-phase wire color code is based on the internationally accepted coding system. Generally, the three core cables used are brown, black and grey. The brown cable is the live wire, the black cable is the neutral wire and the grey cable is the ground wire. Commonly, these core cables have a yellow/green striped insulation which indicates the ground wire. The other wires used in a three-phase wiring system are red and blue. The red is the phase 1 wire, the blue is the phase 2 wire, and the black is the phase 3 wire.
