Single pole switch has 2 wires: These wires are Hot wire from breaker, and wire going to Load (light).

Combo device needs additional neutral wire.
Without a neutral wire, the combo outlet will not work.
Neutral wire connects to silver-colored screw. Neutral wires are the white wires that are twisted together and covered with wire nut and pushed to back of electric box.

Ok you have GFCI combination switch-plug.

Wires coming out of back of device are connected to "Load" wires.
Load are the black and white wires that go to fan, light, motor.

The black and white wires coming from circuit breaker connect to terminals marked "Line"
Look at back of device for markings.
Black wire from breaker goes to brass screw, white wire goes to silver screw.

There is one more set of screws on device. Device usually arrives with tape over these two screws.
This is what those screws are for: If you are working in a junction box, then three cables enter box.
One cable is for Line wires from breaker box.
Second cable goes to Load (light-fan-motor) that is controlled by switch.
Third cable goes forward to another switch or outlet >> and those wires connect to last set of screws on combo device. Black to brass and white to silver.

The 2 whites from the Romex cable go together along with a jumper. Now, the neutral jumper from the white bundle goes to the SILVER screw terminal one the side of the outlet where the LONGER slot is.

The black wire (load/light side), goes to the brass screw terminal on the SAME side outlet.

The OTHER black (line/HOT) wire goes to the opposite side of the switch, the side that has the connecting tab.

The grounding wires go together and then get connected to the box ground.

1) A wiring diagram can be mistaken because wire colors vary.
That's why electricians don't guess, they test.

2) Look at device to be replaced and note what color screw each wire goes to before disconnecting wires.
If old device is single pole switch, then there are 2 brass screws, and one of these screws is connected to Hot wire, and the other screw is connected to Load wire (light, fan, motor, pump)

3) Separate wires inside box for testing.
Do not untwist any wires.
Tape tester leads to wood sticks to keep hands away from power.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot. Hot wire connects to dark-colored screw on combo device.

4) Hot is identified.
Test Hot to all other wires, except bare ground wire.
Tester lights up on Neutral wire. In a single-pole switch box Neutral wires are usually twisted together and covered with wire nut. Neutral wire connects to silver screw on new device.

5) Load wire that goes to light,fan, motor, pump connects to brass screw on new combo device.

6) If you do not have a Neutral wire in your switch box, then outlet will not work.
You can connect bare ground wire to silver screw and have outlet work, but this is not code, and definitely not recommended for a child's room or any room near water pipes or faucets or metal pipes of any kind. You need to add a Neutral wire and/or install GFCI protected device for any bathroom area.

Question is not clear.
What kind of device is the combo device replacing?
Are you replacing outlet with new combo device?
Why does the combo device already have 2 black wires?

Here's what we need to know to answer your question correctly without guessing.
Add a comment and say what kind of device is being replaced with combo device.
Say exactly what wires are on old device and what color screw wire is connected to.

Say what the outlet is doing.
Say what color screws that each wire is connected to on outlet.

Screw color is key to understanding where you are.
Each wire that you have now connects to a certain screw color, and we need to know that information to give you professional answer.

Yes the indicator light can go bad.

Google search: 'cooper switch with indicator light' -or- 'cooper pilot light switch'
Double check amp rating on existing switch to make sure you have correct amperage.

When replacing switch, look at screw colors and location of wires.
Compare screw colors on new switch.
Screws are color-coded and wires attach to same color screw.
Take photo of wiring or draw picture of wiring before taking out old switch.

1) In this situation we need to test the wires.
Electricians don't guess, they test, and a diagram would be guessing which wire color does what.

2) FYI: non-GFCI receptacle located in bathroom is not code, and device will have to be replaced when property is sold. The reason for GFCI is the likelihood of you holding defective electrical gizmo from China in one hand while putting other hand in running water. Or electrical gizmo falling into bathtub occupied by wife with large life insurance policy.
If you have kids using that bathroom, I want you to avoid using non-GFCI device.

3) Your new device has color-coded screws: Dark, brass, and silver.
These colors tell electrician how to wire the device.

4) Let's test to see which wire connects to which screw:
Separate wires.
Use ordinary 2-wire tester from hardware store.
Tape tester leads to wood sticks so hands are away from power.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. Hot wire connects to dark-colored screw on device.
Hot wire is identified.
Test Hot wire to all other wires in box, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire connects to silver screw, and will complete circuit to receptacle.
If box does not have a Neutral wire, the circuit to receptacle can be completed using ground wire on silver screw, but I am not recommending that.
Last wire goes to Load (light, fan, motor). Load wire connects to brass screw, and will complete circuit to Load.

Switch-plug combo:
bare ground goes to green screw
dark screw goes to hot from breaker
silver screw to neutral
brass screw goes to load (light)

You are replacing single pole light switch?
Single pole switch has 3 wires: black and red and bare copper

New device has 4 different colored screws: green, dark, brass, silver
Bare copper goes to green screw.
Black wire goes to dark screw
Red wire to brass screw
Nothing on silver screw for a moment. Test circuit and make sure light turns on-off.
If lights works, then good so far.

Now let look at silver screw. Neutral wire has to connect to silver screw.
In back of your electrical box are white wires twisted together and covered with wire nut.
These are neutral wires.
You must connect another short piece of insulated wire to these neutral wires and run that wire to silver screw.
The neutral wire will complete circuit to receptacle.
If you do not have neutral wire, then receptacle will not work in that box without additional wiring.

Hook up neutral wire to silver screw.
Now turn on power and click switch again.
If circuit breaker trips, then reverse your red and black wires.
Otherwise this should be correct wiring.

There are more than a few ways to wire this device. The switch box where the device is installed _must_ have a neutral wire for the receptacle to work. This is usually a white wire.

The switch box should have at least 2 cables in it. One cable is the incoming HOT(black) and neutral(white) from the circuit breaker panel (or source). The second cable is the outgoing switch leg(black) and neutral(white) to the light. Each cable should have a bare equipment grounding wire.

The most common way to install this device is to connect the hot wire to one of the black screws, pick one. ( I'm assuming that you have _not_ removed the brass tab between the 2 black screws.)

The 2 neutral (white) wires are twisted together under a wirenut along with a pigtail which connects to the silver screw on the device.

The black wire that goes to the light (switch leg) is then connected to the brass or gold screw.

The bare ground wires are twisted together under a wirenut along with a pigtail which is connected to the green screw.

Hi,
Take the black going to the light off the center and hook where the white going to the light is now....then hook the white to the light with the other white and you will be good to go...You almost had it right...

just a couple of adjustments....:-)

Those GFCI's will stop functioning (as they are supposed too) if the electronics is bad. Nearby lightning strikes and power surges can knock out the electronics. Some GFCI's come from the factory bad out of the box. Also if wired incorrectly (make sure the incoming 120 volt wires are connected to the LINE side of the receptacle) The only other thing to check is if there is power to the GFCI. Test for 120 volts at the receptacle box. (testing from hot to neutral will rule out a bad neutral connection). Should read 120 volts. Otherwise, you'll have to replace the outlet :-(

Black to gold, wht to silver grnd to green

Cooper... | Answered on Apr 21, 2009


If it worked before, it should be a wire to wire replacement. You are replacing a regular switch/outlet with another switch/outlet which just happens to be a GFI outlet.
Wire the old switch wires to the new switch and the old outlet wires to the new outlet.
Cut the breaker/s off first !!

Just use a regular single pole switch
