# Frequent question: What does l1 and l2 mean on an electric motor?

Contents

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. … The voltage between two lines (for example ‘L1’ and ‘L2’) is called the line to line (or phase to phase) voltage.

## What does l1 l2 and COM mean?

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. … If you’re circuit is only one way, you can ignore this terminal and it will still work.

## What color wire is l1 and l2?

The red wire is attached to terminal 1 of Line 1 (L1). The black wire is attached to terminal 3 of Line 2 (L2). The green wire is attached to Ground (GND).

## 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 is the voltage between l1 and l2?

Delta-connected transformer.

The voltage between L1 and N, and L3 and N is divided into halves (120 Volt, single phase), while there is 208 Volt (120 x 1.732) between the high leg (L2) and neutral. Split-phase or high leg delta transformers are sometimes found in (older) three-phase electric power installations.

## What is difference between l1 and l2?

It turns out they have different but equally useful properties. From a practical standpoint, L1 tends to shrink coefficients to zero whereas L2 tends to shrink coefficients evenly. L1 is therefore useful for feature selection, as we can drop any variables associated with coefficients that go to zero.

## What is COM l1 l2 in wiring?

One way switch

As seen previously, a one-way switch contains two terminals. When the switch is on, both terminals are connected together. Typically, these terminals will be marked COM and L1, or sometimes L1 and L2. … This is the most common type of switch, and is used where a light is controlled from a single switch.

## Does l1 and l2 matter?

Does l1 and l2 matter? 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.6 мая 2020 г.

## Is blue wire live or neutral?

The blue wire is known as the neutral wire and its job is to take electricity away from an appliance. The brown cable – known as the live wire – actually delivers electricity to your appliance. Together, these two wires form a complete electric circuit.

## What color wires go to XYZ?

I normally use Green for ground, White for Neutral, Black for X, Red for Y (and orange for Z on an L21-30). On the Cal Standard plugs and connectors the X is colored Red and Y is colored Black.30 мая 2007 г.

## What does l1 and t1 mean on a switch?

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. T1 T2 T3 T4 T5 Motor Lead Wires.

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

The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw. This wire is sometimes red. The green or bare copper (ground) wire, if the device has one, attaches to the green screw terminal on the switch or to the electrical box.

## Can live and neutral be reversed?

There are no polarities in AC, so live and neutral can get interchanged without any problem in AC circuit in appliances. … But if the connection is reversed, you will get a shock when you touch the live wire while opening the appliance for carrying out any maintenance, even if the switch is made off.
