What color wire should I use for a hot wire?
However, common practice (per local electrical inspectors) is for the first hot (live or active) wire to be black and the second hot to be red. The recommendations in Table below are by Wiles. He makes no recommendation for ungrounded power system colors.
What color conductors are used for 208 VAC?
Black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC. Conductors larger than #6 AWG are only available in black and are color taped at the ends.
What color is the ground for DC power?
US DC power: The US National Electrical Code (for both AC and DC) mandates that the grounded neutral conductor of a power system be white or grey. The protective ground must be bare, green or green-yellow striped. Hot (active) wires may be any other colors except these.
What color is the protective ground?
The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
What is the color code for electrical wiring?
IEC (International Electrotechnical Commission) Throughout most of Europe and in the United Kingdom (UK), the International Electrotechnical Commission mandates electrical wiring color codes for all functions. Single Phase Line (labeled as L): brown. Phase 1 (labeled as “L1”): brown. Phase 2 (labeled as “L2”): black.
What color is the neutral wire?
The neutral conductor must be gray and the protective ground must be either green, green-yellow, or bare copper.
Do electrical wiring have color codes?
Most countries have a governing organization that implements color coding requirements for electrical wiring. In cases where there are no legal requirements, specific colors have been adopted as local practice and are recommended.
What color should a phase 1 volt switch be?
Phase 1 - Phase 1 wiring should be black. Phase 2 - Phase 2 wiring should be red. Phase 3 - Phase 3 wiring should be blue. Neutral - Neutral wiring should be white. Ground - Ground wiring can be green or green with a yellow stripe. In some uncommon situations, one phase will have a higher voltage than the others.
What color wire is used for DC power?
The coloring is as follows: Positive - The wire for the positive current is red. Negative - The wire for the negative current is black. Ground - The ground wire (if present) will be white or grey.
What color is phase 1?
Due to the serious potential for deadly electrocution or other issues, getting these color codes right is essential. Phase 1 - Phase 1 wiring should be brown . Phase 2 - Phase 2 wiring should be orange.
Can you apply color standards to existing wiring?

How to find the other colors of a circuit?
If you remember the color pattern black, red, blue, then you can figure out the other circuit colors by finding the closest multiple of 6 and backtracking. For example, if you had to pull wire for circuit 21, you would find the closest multiple of 6, which is 24.
What color wire is needed for circuit 21?
Since 23 and 24 are both blue, it means that 21 and 22 are both red, so the color wire needed to install for circuit 21 is red. I had to write out a cheat sheet chart for myself in the notebook I carry with me. It really helped me to visualize what a panel would look like. Hopefully some of this makes sense.
