How do you wire a simple switch?

Quote from the video:
Quote from Youtube video: So with the power turned off we run the black hot wire to the bottom terminal of the switch. Then. We run another hot wire over to the sealing box and into the light fitting.

What does L1 and L2 mean on a switch?





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.

How do you wire a simple 2 way switch?

Quote from the video:
Quote from Youtube video: We need to place a brown sleeve at each end to warm this is intermittently live lastly to complete the circuit we connect terminal l2 back to the supply for the light fitting.

How do you wire a single pole switch?

Quote from the video:
Quote from Youtube video: So we have the ground ready to go and here's a single pole switch. So we're gonna go around the green terminal in the clockwise manner. We're gonna crimp and tighten it down securely.

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

In the case of a single-pole switch, these wires are interchangeable—it doesn’t make any difference which wire is attached to which screw terminal. Inside the switch is a metal pathway that closes when the switch is in the ON position and opens to interrupt the flow of power when the switch is turned OFF.

Does the black wire go to L1 or L2?





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.

What happens if you wire a light switch wrong?

But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work, but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.

Does live wire go to common or L1?

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 Colour wire goes to L and N?

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 is L and N in switch?



There are two different name, L (Live) and N (Neutral) on the AC input terminal. Please refer to Fig. 1 for the wiring of the AC input.

What wire goes to common on light switch?

black wire

Two white (neutral wires) will be connected and covered with a wire nut. A black wire will be connected to a black or copper screw terminal—this is the “common” wire—and you must distinguish it from the other wires.

Which wire is hot when both are same color?



In most modern fixtures the neutral wire will be white and the hot wire is red or black. In some types of fixtures, both wires will be the same color. In this case, the neutral wire is always identified by some means. In some cases, there will be small writing on the wiring case.

What happens if you wire 3 way switch wrong?

If you don’t correctly connect this wire, then your lights won’t work from more than one switch. Grounding the switch: You’ll also need to locate the ground wire and connect it to the switch too.

How do you know which wire is hot and black?

As a further test, place the prongs of the multimeter’s wires on the bare metal on the ends of the two black wires. You will get a reading if one wire is hot and the other isn’t. However, if both wires are hot, the reading will be zero.

What happens if you mix up hot and neutral wires?

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.

How do you tell which wire is hot on a light switch?



Quote from the video:
Quote from Youtube video: So go ahead and touch. Your black probe to ground. And put your red onto the hot. And so there you can see 120 volts.
