The ground wire is for safety.
Black white green electrical wire.
Cable consists of one or more conductors wrapped in a sheath.
Red or orange can also be used as a second switched power wire in a 120 volt application.
The mandatory colors for power wiring in national electric codes nec are green bare or green yellow yellow strip or band on green for protective ground pg and white alternatively grey for neutral wire.
With only a white and black wire coming from the electrical box for the fixture.
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 connect an outlet or light switch the black wire goes to the brass screws.
Wire and cable are products that carry an electrical current from a power source to devices and equipment.
When you re done join the two halves of the plug casing and tighten the screws to hold it together.
Now the white wire is the neutral and is only attached to the white wire of the fixture.
The purpose of green wires is to ground an electrical circuit.
In that wiring scheme assume the black and re marked white wires are live.
White and gray electrical wires can only be connected to one another.
Black green white wire cable.
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.
Or the bare can be attached to the box so it bonds the light fixture.
Wire is characterized by a solid or stranded conductor protected by insulation and or a jacket.
Sometimes you ll find a white wire with a piece of black electrical tape wrapped around it.
Loosen each terminal screw hook the wire around it and put the screw down tightly.
By convention that means the wire is hot.
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.
The ground wire goes to the green screw.
Any other colors expected the above mentioned can be used for live line or hot wires.
We attach the bare wire to the box and leave it long enough to be attached to the light fixture bare wire.
