Electrical Outlet Black And White Wires

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 outlet black and white wires. In a 110 volt setup an additional wire usually red or blue normally indicates a hot wire controlled by a light switch. The colors regulated by the national electrical code in the united states are standardized for safety. The white wire is always neutral and when the cable has only two conductors as most 120 volt cables do the hot wire is black. The white wire goes to the white metal screws on an electrical outlet.

I have an old outlet that has three black wires and three white wires along with the grounding wire. On a conventional 120 volt two pronged electrical outlet that accepts grounded plugs two prongs plus the rounded center ground connector prong your circuit will have three wires. A series means there are 2 or more outlets powered by the same wiring and circuit. To which screws on the electrical receptacle shown just above do we connect the black wire white wire and ground wire.

So where do the wires go. And what if there is no ground wire. Right now 2 of the black wires go to the back of the outlet while the other wire goes to the side and screws in. According to standards in use since the mid 1900s a wire color code identifies the purpose of each wire in an electrical circuit.

Same thing with the whites.
