What is a red wire used for?
What are Red Wires? Red wires are usually used as secondary hot wires. Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch maybe.
What is the color code for 3 phase wiring?
The wires, called conductors, used in a three-phase power system are normally color-coded, although the colors vary greatly by location, and most countries have their own codes. North America traditionally uses black, red, and blue to represent the three phases, for example, while white represents the neutral wire.
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 is the wire color code?
Wire Color Standards. NFPA 70 – National Electrical Code (USA) Grounding conductor (“protective earth”/“ground”): wires must be bare, green, or green/yellow striped. Grounded conductor (“neutral”): wires must be white or gray.
