What are the 3 wire Colours?
US AC power circuit wiring color codes 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 color is automotive ground wire?
green
In the U.S., most ground wires will be green. Some systems will use a green wire with a yellow stripe for the ground. Any color of wiring can be used for electrical components and accessories.
What wires go to what color?
Blue and yellow wires are sometimes used as hot wires and as travelers, green wires (and bare copper wires) are ground wires, and white and gray wires are neutral.
What is the white wire in automotive wiring?
If I run into a black wire in a harness with many other colors, I always assume black will be ground. However if I run into a cable with a white and black wire and all it is doing is providing power to a component, I always assume black is hot and white is ground.

What are white wires used for?
The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel. The green wire (or it can sometimes be uncolored) wire is the “ground” wire, it will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.
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.
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 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 color are electrical wires?
Electrical wiring comes in different colors for a reason. Each color tells us something specific about the wire and what it is used for. The most common colors are black, red, blue, yellow, green, and bare copper. Black wires indicate that a wire is hot.
