How do you cap off a light switch wire?

Cap it off with a wire nut and tuck it out of the way. If you’re afraid it might short against something else, wrap some electrical tape around it, but that shouldn’t be necessary. Remove the switch. Replace the cover with a blank wall plate cover, or put a blank insert in the existing cover where the light switch was.

How do you remove a switch from a circuit?





1 Answer

  1. Turn off the power at the panel for this circuit (flip the circuit breaker).
  2. Remove the cover plate from the switch.
  3. Test with a non-contact tester to make sure that there is no power in the circuit box.
  4. Unscrew the switch.

Are switch loops allowed?

At the fixture end, one of the 2 wires the switch is connected to would be connected to the source of power (black on the other cables) and the other is connected to the hot screw of the light fixture. A switch loop wired properly is legal.

What is a switch loop in wiring?

The historical method. Before the code changed, it was common to run a single length of 12/2 or 14/2 cable as a switch loop. This means bringing the power down from the fixture to and through the switch and then back up to the fixture.

Are wire nuts legal in the UK?

Simple to use and the house has not burnt down yet after 5 years so appear to be safe. Show activity on this post. Wire nuts are not used in the UK because the old ceramic ones were banned many years ago for good reason; the same reason outlets are not allowed in bathrooms: 240 volts!

How do you change a loop?

Quote from the video:
Quote from Youtube video: Alright so the difference in a switch loop is that instead of bringing our incoming hot over to the switch first and then running our leg up and creating a loop that comes back to the panel.

What happens if you wire a switch wrong?

If you damage the wires during installation, you could break the switch, or the wires could come loose. Loose wires present a danger when changing the light switch. Thirdly, you could create a short circuit in the switch. A short circuit can cause the breaker or fuse to pop.

Can you use a white wire as a switch leg?

You can use the white or gray conductor within a cable assembly for single-pole, three-way or four-way switch loops if it is permanently re-identified to indicate its use as an ungrounded (hot) conductor at each location where the conductor is visible and accessible [200.7(C)(2)].

Why is there no neutral in my light switch?



Switches don’t get neutrals, they only want 2 wires: hot and switched-hot. Unless you’re dealing with a smartswitch, those take neutrals but there is still a switched hot to account for. And red is a common switched-hot color, but it would never, ever, ever, ever be used for neutral. Ever.

Does a switch leg need a neutral?

Ordinary mechanical switches do not need a neutral, but only hots (line hot and switched hot). Nowadays the code requires a neutral in switch boxes even if it is not used in the original installation.

Can I use a neutral as a hot?

Furthermore, neutral wires can be used as a hot wire if both ends are clearly marked with colored electrical tape (black or red) that corresponds to its repurposed function. In either case, handle them the same way you would a hot wire, and take the same safety precautions.

Can the neutral wire shock you?



You get shocked when current flows through your body. Often, the neutral wire is very close to ground potential, and you are too. So, often, there is not enough voltage to give you a shock.

Can I connect neutral and ground together?

No, the neutral and ground should never be wired together. This is wrong, and potentially dangerous. When you plug in something in the outlet, the neutral will be live, as it closes the circuit. If the ground is wired to the neutral, the ground of the applicance will also be live.
