Hi ,., the two screws on the one side of the combo are for the white , neutral wires, they should be interconnected with a small link. The screw at the bottom of the switch connect the black power wire, then jumper a wire between the other two screws on that side and the switch will be controlling the receptacle.

How you install a light and plug in in one switch

1) Copy following link for wiring combo device:

2) Neutral wire is required for outlet to work.

3) Outlet will be ON all the time.
Some combo devices can be wired so that switch controls outlet, but other models cannot be wired so switch controls outlet.
Look for break-away fin located between dark screws on combo device. If device has break-away fin, then switch can control outlet.

How do you wire in the 2 black wires that are attached to this switch?

There are two wires on back of GFCI combo switch outlet
The switch controls these two black wires on back of GFCI device.
For example if you have a black and white wire going to light.
Black wire going to lights connects to the wire on hot side of combo device.
White wire connects to wire on neutral side of combo device.

I want to install two GFCI receptacles in an outside box. One is the Cooper with the on/off switch and the other a Eagle GFCI (no on/off) can/should this be done? and if so, how? We have wired it several...

Question is a bit unclear and wires are not known.
Are both GFCI devices inside same box?
Not necessary to install 2 GFCI devices inside same box since second outlet/switch can be protected using one GFCI.

1) Typical GFCI outlet device has 4 terminal screws (plus green ground screw for bare copper ground wire)
2) Two of the screws are labeled LINE. These screws are where the black Hot wire and white Neutral wire are connected. Black goes to brass screw and white to silver screw. And now the device has power to outlets, and both outlet are GFCI protected.
3) Two of the screws are labeled LOAD. These screws are where you attach additional outlets/switches that you want protected by GFCI. All outlets connected to LOAD screws would be GFCI protected. So attach black and white wires and run them to an ordinary outlet/switch and it will be GFCI protected. The key is to connect wires to the LOAD screws.
4) If you are using the outlet/switch combo GFCI device, then the same wiring shown above applies. The difference is the wires sticking out of back of device are for the switch. For example if switch controls a light, the wires going to the light connect to the two wires on back of device.

Okay, I have the same problem... It is a cooper combination switch. There are two black wires that are coming out of the back . the instructions don't mention them at all. I am installing a new outlet...

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.

I have a black/white/ground wire coming from my power supply into my bathroom. I want to install a 274w combination device so as I can have one plug outlet and a switch for the shower fan.I need to see a...

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.

I want to change . alight switch ito a combination switch. outlet and light but thiers only two wires runin to light switch

You only have two wires, because it is wired for a switch leg. You only have the incoming hot and outgoing hot to the light. You need a neutral and grounding conductors also. If you're putting this in a bathroom, it should be a GFCI receptacle. You will have to add another wire, or just add another box in the wall.

Hi, I recently had problems with my gfci outlets. I have 4 outlets connected to a gfci circuit and I cant get the other outlets to work if nothing is plugged to that one outlet at the end. The gfci outlet...

that is truly a strange problem, has there been any rewiring going on? almost seems that it wired in a series instead of a paralell circuit and the end one completes the circuit when something is plugged in. i am not sure how to tell to fix this other than to go thru the whole circuit.

at the gfci the line side, or the hot wires supplying it should be hooked up to the line side of the gfci. the wires feeding the rest of ur outlets should be connected to the load side of the gfci.

then at each outlet the hot wires both line and load should be hooked up to the brass or gold looking screws and the neutrals should be hooked up to the silver screws. this way u should have power on all the outlets.

ShockSentry GFCI duplex receptacle child safety

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 :-(
