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.
Most wiring harnesses will have identifying part numbers in different places on the harness. The number will be on a piece of tape wrapped around the harness. If you cannot find any, then you will have to identify it by what it is connected to and the colors of the wires. This way it can be isolated and identified.
What color wires are positive and negative?
Red: The red wire is positive.Black: The black wire is negative. White: The white wire is neutral or ground.
The right-front speaker wires are gray, left-front speakers are white, right-rear speakers are purple, and left-rear speakers are green. Ground wires are black, antenna wires are blue, and amplifier wires are blue with a white stripe.

Hot wire is identified by its black casing. This is the main color of hot wire for most homes. However, other hot wires can red, blue, or yellow, although these colors can indicate a different function besides powering an outlet.
What color wire is always hot?
The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
A black or red-hot wire usually connects to a brass-colored screw terminal or black wire lead on electrical devices. A white neutral wire usually connects to a silver-colored terminal or white wire lead.
How do you know which wire is positive?
The positive wire, also commonly called the hot wire, will typically be black in color. It is the source of the electricity. The electrical current travels from the outlet or other power source on the positive wire, so if it is plugged in anywhere, it should be considered a live (and dangerous) wire.
Can I connect red and black wires together?
Red and black wires are both hot or line wires and should not be connected together.
What color does the white wire go to?
White or gray wires indicate neutral charged wires. However, neutral wires may carry power and pose a danger of electrocution if not handled properly. White and gray wires carry power back to the service panel. Both hot and neutral wires have the potential to shock and injure you if not handled properly.
What do different wire colors mean?
Black wires are hot wires that run to the electrical outlet from the switch. Red wires are hot wires common in a 240-volt outlet or when a wall switch controls the outlet. Blue and yellow wires are hot wires for ceiling fans and three- or four-way switches. White or gray electrical wires are neutral wires.
Does blue wire go to black or red?
Connect black fan wire to the black ceiling wire. Connect the blue wire to the red wire.
Black wires are “hot” wires. They carry current from the home’s electrical panel to the light, appliance or other device that needs electricity.
Which wire is live red or black?
This replaces the old colours of red (live) and black (neutral) and green (earth) which changed back in 2006. If your plug has these colour wires, we recommend that you replace it.
