    Existing was a slide low/med/high switch that controlled my ceiling fan (no lights) but also powers outlets on one wall of my living room, high is why I have 3 black wires. Replaced existing ceiling fan with a new one that has lights and is remote controlled (no pull strings). Replacing old slide switch with on/off Legrand Adorne paddle switch.

    So one of those black wires is not and the others go to the outlet and the fan box. You could use a meter to see what one is what. When you find the hot wire, it goes to one connection on the switch and the other two go to the remaining connection.

Black is the NEC color for residential hot wire. So what does each wire control? Tell us what it is in and what it does and what was present before disassembly.

    Black wire coming from upper left is hot, upper right is ceiling fan and lower right powers the wall outlets.

  • rdjagger Apr 21, 2015

    do a pigtail from hot to wall outlets so they are hot all the time, then another pigtail from hot to wall switch and the fan black to other terminal on wall switch. then the wall switch will control power to fan--on/off.

    neutrals(white wires) seem to be all connected so no problem on completing the circuits apparently, good luck. be careful

SOURCE: how to wire 3 switches in a 3 gang box

WARNING: Do not attempt to do this work unless you completely understand the information provided below. If in doubt call an electrician.
Always make sure the power is disconnected from all possible sources before making any connections. Your description of the problem indicates that there may be multiple power wires coming into the same box. In that case local codes may require that the box be partitioned to prevent exposure to voltages up to 220 volts.
You need to determine where each wire goes to know how to connect them together. You cannot rely on color alone. If the power supply runs through the box to the loads then most (but probably not all) of the white wires will be connected together. If the power runs to the load boxes first then none of the white wires in the switch box should be connected together. They are used to run the switched/dimmed power back to the loads (and should be taped to cover the white in the box). In that case each switch has its own power input and they should not be tied together. A wire (could be black or white with black tape) brings power from the load box, gets connected to the input terminal of the switch and the corresponding black wire carries the switched power back to the load. The fan/light switch will have one power in and a switched power out for the fan and another for the light. The 3-way will have one "power" in (or it could be the final power out to the light) and two "carrier wires that connect to the other 3-way switch. If the power supply goes through the switch box then there will be at least 10 wires in that box. In that case see the attached diagram: a5fa64a.gif

I want to replace a dimmer switch, with a new one. my new dimmer switch has two black wires and one green. The wires inside my wall has three black wires. How do l connect them?

Assuming you mean the old dimmer switch has three black wires. The old switch is a three way style switch and your new one is a single pole. You will need to take it back and get a three way dimmer switch.

Separate 1 switch 3 lights

You need separate wire going to each light.
Here are diagrams:
2 single pole switches, before you started to replace
Single pole and 3 pole to control each light separately: must identify black wire to each light. If each light does not have separate black wire inside the switch box, then it is not possible.

Wiring is not fully described: Location of hot wire and neutral wire from breaker box are unknown.
If Hot wire arrives in ceiling box first, the switch box will not have white neutral wires that are twisted together and covered with wire nut. Neutrals will be in ceiling box.

What is known: You are replacing single pole switch attached to one 14-2 wire going to light.
You are replacing light with a fan-light and replacing switch with a 3-pole TM8111 switch.
You have replaced 14-2 wire with 12-3 wire.

TM8111 wiring shows following link:
Fan pull-chain wiring shows following link:
Assume neutrals in ceiling box.
Assume Hot wire in ceiling box: Connect 12-3 black wire to black Hot wire. Connect 12-3 white wire to black wire on light. Connect 12-3 red to red wire on fan.
White neutral from fan and white neutral form light connect to other white neutral wires and covered with wire nut.
Wiring at switch:
Black Hot wire from ceiling box connects to A COM terminal.
White wire to ceiling light connects to A SP2
Red wire to fan connects to A SP1

Does this switch wire like a normal single pole switch ? Why does it look like a three way switch? and why is the so called ground screw silver like the nuteral

I am not sure which switch you have. The Hubbell HBL 1281 is shown in the catalog as a single pole switch. It comes in several models. One model has a single lever that goes up (ON) and goes down (OFF).
Another model is a push button. Push once and it is ON, push again and it is OFF.
The above two switches are to be wired to break the hot (black) wire going to the controlled device. Hot should be connected to the bottom, generally, load should be connected to the top.
There is no NEUTRAL wire location. If there is a ground screw, it should be green.

There is also a three position model that operates two circuits, the middle position is OFF for both circuits, the top is ON for one circuit and the bottom is ON for the second circuit.

My GE lighted rotary dimmer switch has 3 wires coming from the same hole- 2 black and one red. Is the red wire the ground wire?


It is most likely a three way dimmer, where the two black wires would run to the other three switch, and the red wire would either run to the breaker panel or the light fixture (depending on the electrical box location).

If you're using this in a single-pole application, place a wire nut on one of the black wires, and then wire it as a single-pole device using the red wire and the remaining black wire.

And make sure you have the power turned off before attempting.

I am replacing a single pole light switch. The original one is older and had a black and a white wire screwed into the side and a black and red wire poked into the back. Where do these wires go in a new...

Most single pole light switches that you buy now days have a quick connect feature. The wire is shoved into the back hole after skinning and the gripper teeth keep it from coming loose. This was to make the wiring job faster for the electrician. It also has side screws so that you can run multiple wires if you need to. I suspect that your new switch is just side screws (which you can buy). I do not know why you have a red wire as that normally is used in a three way switch. Are you sure that you don't have a three way switch, that is you can turn the light on or off at two locations. Check out

How to install a dimmer switch

This is a 3-way switch, made to control a light fixture that is also controlled by another switch in a different location. A typical example is a ceiling light fixture installed in an upstairs hallway, which could be controlled by switches at both top and bottom of the staircase.

The green wire in your switch is the ground connection, and joins to the green insulated or bare copper ground wire in the switch box. The red wire is the common connection. It connects either to the incoming AC hot wire from the electric panel, or to the hot terminal of the light fixture, depending on the switch location. The two black wires are traveller connections. They connect to the traveller terminals of the other 3-way switch.

If you purchased this switch as a replacement for a regular single-pole toggle switch or dimmer switch - one that controls a light from a single location only - then this isn't what you need and you can't use it. You'll know if you have a single-pole switch because it will have only three wires or screw connections. Return it and get a single-pole.

To install this as a replacement for a 3-way toggle switch or dimmer, connect the red wire to the wire going to the common terminal of the original switch. This will be a black- or brass-colored screw on a toggle switch, or the different-colored (not green, that's ground) wire on a dimmer. The black wires connect to the wires that go to the traveller screws (copper-colored) on a toggle switch, or the same-colored wires on a dimmer. It doesn't matter which traveller wire connects to which.

Note that if you're using a 3-way dimmer, only one of the switches can be a dimmer. The other switch has to be a plain old 3-way toggle.

so 6 grounds is connected together, and conneted to mains ground (direct connection), the white wires is (mains Neutral) and you connect all 6 white wires together (to doble pole safety switch) in one end pole switch, and you connect a wire from another pole the same end at common Two Single Pole Switch and connect (Black wires recess lights) to one free pole switch and (Black wires track lights) to another free pole.

The mains connect to safety switch live (Black or Brown) to another free safety switch pole, Neutral (White or blue) to free safety switch pole and earth to ground wires on mains connector.

Note: Allways use a mains 300mA diferencial safety switch, for better protection.

Want to install ab switch

hello. this installs just like a regular switch. NOW let me ask you one important question. Is this the only switch that controls the light or are there two or more.

if it is the only switch, called a single pole switch all you do is kill the power, remove the old switch and connect the two black wires to the new switch, and the ground wire[if there is one] to the ground screw.

if there are two switches that control this light you have what is called a three-way switch. it is still easy to change but you must change using a three way AB switch, not a single pole switch.

Also, you can only put the AB switch at one end, not both.

Problem w/new sliding dimmer

The problem is that the Cooper #9530DS-K-L is actually a 3-way switch and you need a single pole dimmer switch to replace your existing single pole toggle switch.

If you want to use the Cooper switch you have you can take one of the black wires and cap it with a wire nut and connect the other two wires, but frankly, you'd be paying about 2 times the price for a 3-way dimmer switch when you only need a single pole switch.

You should be able to return the switch and get the correct one.

You should only have (2) black wires on the proper replacement switch, plus a ground wire

Hope you found this very helpful and best regards!
