What does L1 and L2 mean in electrical 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. The voltage between two lines (for example ‘L1’ and ‘L2’) is called the line to line (or phase to phase) voltage.

What Colour wire is L1?

blue wire
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 COM L1 and L2 mean?

Two way switching means you can switch the same light fixture from two switches that are located in different sides of a room. 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 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.

What Colour wire goes in L2?

Red for L1, Yellow for L2 and Blue for common. Brown for L1, Black for L2 and Grey for common.

How do you know if its L1 or L2?

Recognize that the black wire is the positive one, the white wire is the negative one, and the green wire is the ground. 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).

Does the black wire go to L1 or L2?

Brown for L1, Black for L2 and Grey for common.

Is blue wire L1 or L2?

These two wires are the Permanent live and switched live. The Yellow wire goes in the common terminal, Red in the L1 terminal and Blue goes in the L2 terminal. The Grey wire goes in the common terminal, Brown in the L1 terminal and Black goes in the L2 terminal.

What Colour wire goes to L2?

What does L1 L2 L3 mean on a light switch?

Again, some makes of switch may have alternative markings such as L1 L2 and L3. This type of switch is used where two switches control one light, such as at the top and bottom of a stairway. It can also be used as a one way switch, by using the COM and L1 terminals only.

Is L1 positive or negative electricity?

Also, which wire is positive black or white? Recognize that the black wire is the positive one, the white wire is the negative one, and the green wire is the ground. The red wire is attached to terminal 1 of Line 1 (L1). The black wire is attached to terminal 3 of Line 2 (L2).

Is L1 live and L2 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)….Is l1 live or neutral?
