What color wire goes where on a light switch?

A standard single pole light switch will simply require you to attach the black (load) wire into it, and then the black wire leaving the switch and to your lights. The switch serves to cut the power from reaching the light switch. The white or neutral wire bypasses the switch and goes straight to your lights.

Does it matter which wire goes where on a light switch?





It doesn’t matter as long as you do it the same on both switches. So, if you connect it to the upper right terminal on one switch, connect it to the upper right terminal on the other switch. Connect the second traveler wire to the terminal opposite the red wire terminal.

How do you wire a occupancy light switch?

Quote from the video:
Quote from Youtube video: The light it is providing the electrical. Current so I'm gonna go ahead and remove this wire up here at the top from this existing. Light switch.

What is COM L1 and L2 on a light switch?

Two way switches have a COM terminal as well as L1 and L2 terminals. When L1 is off L2 would be on. When L1 is on L2 would be off.

What are the 3 wires on a light switch?

With a three-way switch, three wires connect the pair of switches—two black “traveler” wires and a third “common” wire. When the circuit’s power is turned on, any of these may be “hot,” depending upon how the switches are toggled.

What are the red white and black wires on a light switch?





Going out of both boxes and into your light fixture will be 14/3 wire, which has a black wire (hot), a white wire (neutral), a red wire (traveler), and a bare copper wire (ground). Twist the two copper wires in the first box together and attach them to the ground nut on the switch.

What happens if you wire a light switch wrong?

But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

What happens if a light switch is wired backwards?

When an outlet is wired in reverse, the hot wire is now on the supposed neutral side. So, if you were to plug in the same lamp as noted above, the lamp socket would have power even if the switch was off since the switch is only on the hot side.

Does my light switch have a neutral wire?

Remove the wall plate of the existing switch by either snapping it off or unscrewing it. Unscrew the existing switch from the electrical box and slowly pull it out just enough to reveal the wires connected to it. If you see a white wire, or a group of them, then you have neutral wiring.

How do you know if its L1 or L2?



L1 (line 1) is a red wire and L2 (line 2) is a black wire. Together, they show the motor voltage. Having both an L1 and L2 indicate that the motor voltage may be 240 volts.

Is L1 and L2 the same as 1 way and 2 way?

A two way switch (for switching a light from two different locations like in a hallway) has a common (C) a L1 and an L2 terminal. L1 is off when L2 is on and vice versa depending on the switch position. You can use a two way switch for one way switching. Just ignore the L2 terminal.

Is L2 live or neutral?

L1 is live and L2 is neutral.

Does neutral go into L1 or L2?



Changing a light switch



The faceplate of a single, one-way switch has two terminals: “L1” is the terminal to which the neutral core wire is attached – the blue wire (traditionally black, before the change).

Can I use a 2 way light switch as a 1 way?

A two way switch can be used as a one way switch or a two way switch. They are often used as both. In fact many electrical retailers (including Socket Store) don’t sell one way switches as the price difference is insignificant and the two way will do the job for both.

What is L1 and L2?

L1 is a speaker’s first language. L2 is the second, L3 the third etc. A learner whose L1 is Spanish may find Portuguese and Italian easy languages to learn because of a fairly close connection between the languages.

What Colour wire goes to L1 and L2?

US AC power circuit wiring color codes

Function label Color, alternative
Line, single phase L
Line, 3-phase L1 brown
Line, 3-phase L2 orange
Line, 3-phase L3 yellow

What Colour wire goes to L2?



The yellow wire goes into the common terminal, red goes into the L1 terminal and blue goes into the L2 terminal. The grey wire goes in the common terminal, the brown wire goes in the L1 terminal and the black wire goes in the L2 terminal.

What is the voltage between L1 and L2?

The voltage between two lines (for example ‘L1’ and ‘L2’) is called the line to line (or phase to phase) voltage. The voltage across each winding (for example between ‘L1’ and ‘N’ is called the line to neutral (or phase voltage).

What color wires go to L1 L2 L3?

The USA has their own wiring colors for electrical circuits, black, red, and blue are used for 208 VAC three-phase; brown, orange and yellow are used for 480 VAC.



International Wiring Color Codes.

Ground (G) Green
Neutral (N) Black
Line 1 (L1) Red
Line 2 (L2) Yellow

What does L1 and L3 mean?

Terminology. The three winding end connected together at the centre are is called the neutral (denoted as ‘N’). The other ends are called the line end (denoted as ‘L1’, ‘L2’ and ‘L3’). The voltage between two lines (for example ‘L1’ and ‘L2’) is called the line to line (or phase to phase) voltage.
