What color wire connects to black?
Power comes from the service panel along the black (hot) wire through other outlets, switches and light fixtures on the circuit and begins its return to the source through the white (neutral) wire. The black wire attaches to a brass terminal; the white wire, to a silver terminal.
What does the red wire connect to?
Black or red wires always carry power from the service panel (breaker box) to your home’s devices. 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.
What does yellow wire mean?
Blue and yellow wires are most commonly found in commercial buildings and are used as the live wires pulled through a conduit. Yellow wires are used as switch legs to ceiling fans, structural lights, and outlets paired with light switches, while blue wires are usually used as travelers for three-or-four-way switches.
What does a yellow wire mean?

Yellow is positive, blue is negative. With the 12v wall plug I used it’s red to yellow, black to blue. 3 of 3 found this helpful.
What do I do with the green and yellow wire?
Green, green with a yellow stripe, and bare copper wires can only be used for grounding purposes. A ground wire can never be used as a neutral, even though it connects to the same bus at the main panel—that’s a huge safety violation that can cause electrical shock, serious injury, or death.
Are green and yellow wires the same?
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. However, all electrical wires, regardless of their function, may carry an electrical current at some point and should be treated with equal caution.
What does a yellow and green wire mean?
Green, Green-Yellow and Bare Ground wires reduce the risk of electrical overload and fires by redirecting excessive electricity during a short circuit or similar fault. Consequently, they can conduct electricity and should be handled with caution.
