Which Side Of Outlet Is Black Wire

A little hard to read but the left side says hot wire and the right side says white wire.

Which side of outlet is black wire. The united states has strict codes relating to home wiring including clearly defined colors on the outer casing of the wires. The typical electrical wiring for a 120 volt outlet is the following. We ll put the black wires on the hot side and the white wires on the left side. At the second device the line is the power source coming in.

How to wire a pilot light switch. The bare or green ground wire attaches to the green screw terminal typically found at the bottom of the outlet. The three wires in a standard nmb cable are connected to the three prongs of a standard electrical outlet properly called a receptacle. The white wire goes to the white metal screws on an electrical outlet.

The red wire switched hot wire going to the outlet wires into the other side of the switch and the white wires neutral tie together to complete the return side of the circuit. The black power wire attaches to the brass or gold side screw terminal. As you can see the neutral and hot wires are connected to the two vertical prongs at the top of the receptacle neutral on the left hot on the right and the ground wire is connected to the round prong at the bottom of the receptacle. In a 110 volt setup an additional wire usually red or blue normally indicates a hot wire controlled by a light switch.

When you connect an outlet or light switch the black wire goes to the brass screws. The white neutral wire attaches to the silver side screw terminal. Two silver colored screw terminals for attaching neutral circuit wires two bronze or copper colored screw terminals for the hot circuit wires and a green screw terminal fixed to the strap of the receptacle which is used for the bare copper ground wire or a green ground pigtail wire. Outlets receptacles switches light fixtures and other electrical devices typically are wired in multiples on a single circuit.

The ground wire goes to the green screw. When measured with respect to the white neutral wire the red wire carries the same 120 volt current that the black one carries making the voltage across these two hot wires 240 volts. One of the hot wires attaches to a brass terminal on one side of the outlet and the other attaches to a brass terminal on the other side. However if you need to rewire a light switch or a plug socket you may occasionally come across two black wires.

Anatomy of an outlet receptacle. There is a break way fin tab intact to the line hot side which can be removed if switch is needed to control additional load otherwise a jumper wire can be added between the switch load terminal and lower line terminal while removing the. Standard outlet receptacles will have a total of five screw terminals. It is tied together with a wire going to the switch and the black wire going to the outlet.

The other set of black and white wires goes to the next outlet down the line and that s how it gets its power. The black wire hot wire coming in from the left is the source power.
