The different colors of electrical wires indicate the function of the wire with black and red indicating the wires carry electric current white usually indicating neutral charge and green indicating the wire is grounded.
Electrical green wire white black.
White and gray electrical wires can only be connected to one another.
Red or orange can also be used as a second switched power wire in a 120 volt application.
The white wire goes on the silver terminal the black wire on the brass one and the green wire on the green one.
When you re hanging a chandelier or any other ceiling light first find the 3 wires coming out of the hole in the ceiling where the light will go.
Now the white wire is the neutral and is only attached to the white wire of the fixture.
In that wiring scheme assume the black and re marked white wires are live.
Sometimes you ll find a white wire with a piece of black electrical tape wrapped around it.
With only a white and black wire coming from the electrical box for the fixture.
The colors regulated by the national electrical code in the united states are standardized for safety.
The purpose of green wires is to ground an electrical circuit.
While they re called neutral wires they may still carry a current especially if the current load in the circuit is unbalanced so handle these wires cautiously.
If you have a ground wire it s green or bare.
When you re done join the two halves of the plug casing and tighten the screws to hold it together.
We attach the bare wire to the box and leave it long enough to be attached to the light fixture bare wire.
The ground wire goes to the green screw.
Recognize that the black wire is the positive one the white wire is the negative one and the green wire is the ground.
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 it s acting as a hot wire and is no longer neutral.
When you connect an outlet or light switch the black wire goes to the brass screws.
By convention that means the wire is hot.
The ground wire is for safety.
Green wires connect to the grounding terminal in an outlet box and run to the ground bus bar in an electrical panel.
Or the bare can be attached to the box so it bonds the light fixture.
