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.

Then, What does l1 l2 mean?

L1 and L2 Motor Wiring

The L symbol designation refers to the Line, or the incoming circuit wires that provide the power for the motor. For example: L1 and L2 indicate that the motor voltage may be 240 volts.

Considering this, Does l1 and l2 matter?

One way switch

When the switch is on, both terminals are connected together. Typically, these terminals will be marked COM and L1, or sometimes L1 and L2. Either way, it does not matter which wire is connected where. This is the most common type of switch, and is used where a light is controlled from a single switch.

This is a key term if you need to cut down the word count in your writing; “L2 classrooms” is 37 characters shorter than “second language and/or foreign language classrooms”.

## What is the red wire for?

Red electrical wire indicates the secondary live wires in a 220-volt circuit, used in some types of switch legs and in the interconnection between smoke detectors that are hard-wired into the power system. You can connect a red wire to another red wire or to a black wire.

## What size wire can you re identify?

In sizes larger than #6 you can reidentify a conductor as a grounded conductor, other than a green one, typically with a band of white tape at both ends. You cannot use green or green with yellow stripes for anything other than an EGC (i.e.-they cannot be reidentified).

## What does l1 and l2 mean on a thermostat?

A US manufacturer would label them as L1, L2, T1, T2 as you noted, because L1 and L2 are the incoming Line power. L1 and L2 are both βhot legsβ of our split phase power system and measure 240v across them, as opposed to 120V if measuring L1 to Neutral.

## Is Blue active or brown?

The Active wire (high potential) is coloured brown (used to be red). The Neutral wire (low potential) is coloured blue (used to be black). The Earth wire is striped green and yellow (used to be only green).

## Is the brown wire live?

The blue wire is known as the neutral wire and its job is to take electricity away from an appliance. The brown cable β known as the live wire β actually delivers electricity to your appliance. The green and yellow cable is known as the earth wire and it serves an important safety role.

## What wire colors mean?

## Is the brown wire positive or negative?

Only our smaller and residential lights use the black and white colors. Brown is your hot wire so you want to connect that to your building’s black wire. The blue is negative or return, so that will go to white. Green with yellow stripe is the ground and will go to the building green.

## What is difference between l1 and l2?

Typically, developing children acquire the language that is spoken and heard in their homes, making that their first language (or L1). In a home where only English is spoken and heard, English will become the L1. Both children and adults have the capacity to also learn a second language (or L2).
