Turn off the power to the switch at the main circuit breaker or fuse panel. Unscrew and remove the switch plate; then use a voltage tester to make sure that the circuit is dead. Unscrew the switch from the electrical box and pull it out with the wires still attached.

Considering this, how do you turn off a light switch?

To disable a light switch, remove the two wires from the switch and tie them together with a wire nut. With the power off, of course. You only need simple tools and materials to do this. You need a slotted screwdriver, two wire nuts, a blank light switch insert or blank wall plate, and possibly some electrical tape.

Secondly, should I use plastic or metal electrical boxes? Plastic boxes don't use metal cable clamps and do not provide the required grounding path. Metal electrical boxes are primarily used with metal-sheathed or “BX” wiring. However, they can also be used with Romex or NM wiring if desired. Most new residential electrical systems use Romex and plastic boxes.

Likewise, what to do with wires when removing a wall?

Shut off the main power if there is live electricity running through the wall and take care when removing walls with existing plumbing. Put down the sledgehammer and use a saw to cut out the drywall to reveal the pipes behind it. Turn off the water main and consult with a plumber before removing any pipes.

How do you replace a junction box?

Follow the National Electrical Code (NEC) when replacing a junction box.

  1. Turn the main breaker off in the panel box or, if you know which circuit is in the junction box, turn off the breaker to the circuit.
  2. Remove the cover from the junction box you are replacing.
  3. Remove all of the wire nuts from all of the connections.

How do you cover an unused phone jack?

You can hide the phone jack with a message board made of cork, a dry erase board, or a chalkboard. If the jack sticks out too far for the message board to hang flat against the wall, attach a thin, empty picture frame to the back of the board to hold it away from the wall.

How do you replace a wall switch?

To replace this kind of switch, follow these steps:
  1. Turn off the power to the switch at the main circuit breaker or fuse panel.
  2. Unscrew and remove the switch plate; then use a voltage tester to make sure that the circuit is dead.
  3. Unscrew the switch from the electrical box and pull it out with the wires still attached.

How do you get a broken screw out of the electrical box?

Grab the back of the screws with a pair of 9's (linesmans pliers) and rotate them through (turn clockwise from the front). If that doesn't work, you can drill it out carefully with a 5/32″ bit and re-tap the threads with a tapping tool.

How do you remove an old junction box?

How to Remove a Metal Junction Box
  1. Turn off the circuit to the metal junction box at the main service panel.
  2. Untwist any wire connectors from wires inside the box.
  3. Look inside the metal junction box for where the wires enter.
  4. Examine the interior of the box for any screws in the sides or the back of the box.

Do I need an electrician to change a light switch?

Replacing light fixtures

If the amperage isn't high enough to cover the wattage of your new light, you will need an additional wire run from your circuit breaker. It's best to hire a licensed and qualified electrician for such a task.

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

If your switch has a “LINE” marking, the always hot wire goes to this. The other connection will be “LOAD” where the load (ie light fixture) is wired. The load wire may have red electrical tape on it to differentiate.

What happens if you wire a light switch wrong?

If either wire at the light fixture is still hot then the switch is wired incorrectly. If one of the wires is still hot at the light fixture with the switch in the off position, then you most likely have the light switch on the neutral wire. Separate the bare ends of the wires so you can safely turn the power back on.

How light switches are wired?

The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.

Can you change light switch without turning off power?

2) Always turn off the power to the switch at the main circuit breaker or fuse panel if you are not expert in handling electricity work. 3) You can just use a light to see if the power is definitely off. Turn off power at the box, plug in a light, if it does not light, you are ready to work.

Can you change your own light switch?

If a switch is damaged, or you just want to update your fittings, it's quite simple to replace it. Just make sure you write down exactly how the old switch was wired before you disconnect it, and wire the new switch in the same way. Also, try and keep hold of your original screws.

Why would a light switch have 3 black wires?

If the light turns on, the second black wire you connected to the switch is the switch feed and the unconnected black wire is the feed to the other loads. If the light doesn't turn on, then it's the other way around: the connected wire feeds the other loads and the disconnected wire is the light feed.

Can you bypass a light switch?

Yes, you can safely bypass a switch. It's no different than having a solid length of wire, or a closed switch (electrically speaking). In the US, a twist-on wire connector (wire nut) would be the preferred connector.

How can I eliminate one 3 way switch to leave just one switch on the lighting circuit it's on?

2 Answers
  1. replace that switch with a single-pole switch.
  2. connect either of the “traveler” wires to the load side.
  3. remove the other (unwanted) switch and connect the traveler wire used in step-2 to the “switched hot” wire that goes to the lights.
  4. the unused “traveler” wire is abandoned.

How do you remove backstab wires?

MAKE SURE POWER/BREAKER IS OFF YOU WILL BE TOUCHING A “LIVE” WIRE Insert a small jeweler screwdriver in the rectangular hole/slot, use the box as your pivot point and the screwdriver as your level (bring back end of screwdriver towards wire to force “tab” away) and gently pull the wire out.
