What color is line and load

US AC power circuit wiring color codes The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.

What Colour wire goes to L and N?

The N is for the neutral side or the white wire, and the L is for the load side, the black wire.

What happens if you switch line and load wires?

With simple on-off light switches, mixing up the line and load wires won't affect the operation. The power will be either off or on. It does become critical is when installing a GFCI outlet. Because it contains an internal circuit breaker, incorrect installation can cause a safety failure.

What happens if you switch line and load on GFCI?

If you mistakenly connect the LINE wires to the LOAD terminals, the GFCI will not reset and will not provide power to either the GFCI receptacle face or any receptacles fed from the GFCI.

Is white wire load or line?

The black wire is the "hot" wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the "neutral" wire, it takes any unused electricity and current and sends it back to the breaker panel.

What are the wire color codes?

U.S. Electrical Wiring Color Codes

Phase 1 - Black.
Phase 2 - Red.
Phase 3 - Blue.
Neutral - White.
Ground - Green, Green with Yellow Stripe, or Bare Wire.

Which is line and load on outlet?

There are two types of wires attached to the receptacle. The “line” wires are the incoming power from the breaker box and the “load” wires are the outgoing power that travels down the circuit to the next outlet.

How do you determine neutral and line loads?

You simply use the tip of your voltage tester to touch the insulation of each of the wires to be identified. The wire that gives off a beep or light is your line wire and the other wire is your load wire. Making use of a voltage tester is a safer method than making use of a multimeter to identify your wires.

How do you find line and load on an outlet?

The wires bringing power into the box will connect to the “line” terminals and the wires going to a downstream outlet will connect to the “load” terminals, as follows: The wires bringing power into the box: Black hot wire —> gold “line” terminal. White neutral wire —> silver “line” terminal.
