What color of brown wire represents

The brown wire represents the live wire. In addition, the live wire can also be represented by red, green and yellow. The color of the zero line and ground wire of the wire is different from that of the live line. The zero line is usually marked with blue and black colors, and the ground wire is generally marked with yellow and green colors.
