What does L1 L2 and C mean on a dimmer switch?

The wires from your old switch can be connected either way round to the “C” and “L1” terminals of the dimmerswitch. If you are using a push-on/push-off dimmerswitch there is a spare terminal (L2) that you will not need to use for a 1-way circuit.

Does it matter which way you wire a dimmer switch?





It doesn’t matter if you reverse the two switch wires to a single-pole dimmer. But if you’re replacing a three-way switch with a three-way dimmer, label the “common” wire (it’ll be labeled on the old switch) when you remove the old switch so you can connect it to the “common” terminal on the dimmer.

What does C mean on dimmer switch?

common

A one way light switch has two terminals which is a common marked as COM or C. The common is for the live wire that supplies the input voltage to the switch. The other terminal is marked as L1 and is the output to the light fixture.

How do you wire a one way dimmer switch?

Quote from the video:
Quote from Youtube video: You've got one cable coming into the switch from the ceiling rose. So then the brown one is a permanent life and it's connected to the comm terminal and the blue one with the brown.

How do you replace a 2-way dimmer switch?





Quote from the video:
Quote from Youtube video: If no current is detected remove the screws attaching the switch to the electrical box then pull it out unscrew the wires from the terminals.

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 are the 3 wires on a dimmer switch?

Single pole switches will have 3 wires: a hot lead wire, a ground wire, and a traveler wire. Older homes may only have a hot lead and a ground wire. If you have less than three wires, stop and call an electrician.

Do you need a neutral wire for a dimmer switch?

If the light is off, without a neutral you won’t have a complete circuit to power the smart dimmer circuitry.

How do you wire a dimmer switch with two black wires?



Quote from the video:
Quote from Youtube video: Cap. Next connect the two remaining wires from the old switch to the two black wires on the new control it doesn't matter which black wire you choose because they're interchangeable.

What wire goes to L1 and 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.

Is L1 live or neutral?

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). “COM” or “Common” is the terminal to which the live core wire is attached – this is the brown wire (formerly red).

What does L1 and L2 mean in electrical terms?



The incoming circuit wires that provide the power are referred to as the line wires. 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.

What color is L on a wiring diagram?

Blue

*: Typical connector colours B: Black Y: Yellow L: Blue G: Green R: Red The mark L shows the standard mounting posi- tion of wiring harness.

What does L1 and L2?

These terms are frequently used in language teaching as a way to distinguish between a person’s first and second language. L1 is used to refer to the student’s first language, while L2 is used in the same way to refer to their second language or the language they are currently learning.

Are L1 and L2 the same or different?

Together, L1 and L2 are the major language categories by acquisition. In the large majority of situations, L1 will refer to native languages, while L2 will refer to non-native or target languages, regardless of the numbers of each.

What is the purpose of L1?

L1 and L2 are levels of cache memory in a computer. If the computer processor can find the data it needs for its next operation in cache memory, it will save time compared to having to get it from random access memory. L1 is “level-1” cache memory, usually built onto the microprocessor chip itself.
