What does L1 and L2 mean in electrical wiring?
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 Line 1 wire?
Fixed wiring electricity supply requires specific wiring color regulations (bs 7671) to identify different power lines in different countries….International Wiring Color Codes.
| Ground (G) | Green |
|---|---|
| Neutral (N) | Black |
| Line 1 (L1) | Red |
| Line 2 (L2) | White |
| Line 3 (L3) | Blue |
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).
Is L1 load or supply?
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.
What’s L1 and L2?
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.
Which is the hot wire L1 or L2?
You want your “hot” wire on L1 and Neutral on L2 when wiring the new motor. Make sure you operate the voltage selector dial to reflect 115 volts instead of 230 volts.
Is Line 1 white or black?
US AC power circuit wiring color codes
| Function | label | Color, common |
|---|---|---|
| Protective ground | PG | bare, green, or green-yellow |
| Neutral | N | white |
| Line, single phase | L | black or red (2nd hot) |
| Line, 3-phase | L1 | black |
What Colour is L1 and L2?
US AC power circuit wiring color codes
| Function | label | Color, common |
|---|---|---|
| Line, single phase | L | black or red (2nd hot) |
| Line, 3-phase | L1 | black |
| Line, 3-phase | L2 | red |
| Line, 3-phase | L3 | blue |
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.
How do you know if its a line side or load side?
The line side of an outlet is where you connect the incoming source power. The load side is where the power leaves the device (or electrical box) and travels down the circuit.
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.
Is Line 1 hot or neutral?

| Neutral | N | white |
| Line, single phase | L | black or red (2nd hot) |
| Line, 3-phase | L1 | black |
| Line, 3-phase | L2 | red |
What does L1 mean in 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.
What color is the line and load?
The color for the Line wire is usually black and the Load wire is usually red, black, or blue (less common).
What color is neutral in house wiring?
white wire
The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel. The green wire (or it can sometimes be uncolored) wire is the “ground” wire, it will take electricity back to the breaker panel, then outside to a rod that’s buried in the ground.
