What do electrical wire color codes mean?

An electronic color code is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors , diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables.

What is the color code for electric wires?

Electrical wiring in the US follows the same basic color codes: red and black wires denote live wires, white wires serve as the ground, and blue, yellow, or other colors are used for switches or other specific purposes.

What does wire color mean?

Any electrical wire that is red in colour means it is a live wire. It signifies the positive side of the circuit. Red electrical wires also serve as hot wires. They are mainly used in installations that require up to 220 voltages. Another splendid application of the red wire is that it is used as an interconnect wire.

What is the color code for wire?

The National Electrical Code (NEC) says that white or gray must be used for neutral conductors and that bare copper or green wires must be used as ground wires. Beyond that are general, industry-accepted rules about wire color that indicate their purpose.
