The white wire is the neutral wire. The purpose of a neutral wire is to connect to the neutral bus bar a conductive piece of metal within an electrical panel that attracts the electric current for distribution throughout the house.
Alternating Current In Electronics Hot Neutral And Ground
Is the white wire hot. By convention the white wire is neutral the black wire is hot and a green or bare wire is ground. The white wire is called the neutral wire. Green electrical wires green wires connect to the grounding terminal in an outlet box and run to the ground bus bar in an electrical panel. White is most commonly used but gray wires serve the same function. It provides the return path for the current provided by the hot wire. This video is part of the heating and cooling series of training videos made to accompany my.
If you see a white wire marked with black or red or a piece of black or red electrical tape at its ends that means its acting as a hot wire and is no longer neutral. But if you see three or four colors you can probably figure it out. It provides a 120 vac current source. The neutral wire is connected to an earth ground. The copper wire is called the ground wire because it is connected to the earth either directly or through another grounded conductor. This one just demonstrates where the power is in a circuit and where you can have a hot neutral.
The black wire is the hot wire. The black wire is the hot wire which provides a 120 vac current source. White and gray electrical wires can only be connected to one another. So if you see lots of different colors in an electrical box you probably need to call an electrician. But the first rule is there are no rules. It provides the return path for the current provided by the hot wire.
