If the switch is an integral part of the GFCI outlet then it shouldn't need wiring.
I'm running on the assumption that your outlet is the same as those I have installed myself...
To wire a switch AFTER a GFCI...
There should be two brass coloured and two silver coloured screws on the outlet. The power from your panel attaches to the screws marked LINE and the wires that go to the switch are attached to the screws marked LOAD. This protects anything plugged into the outlet as well as the "fixture" served by the switch.
One VERY important issue is the grounding...Cut yourself a small (7" should do, 10" is about the limit) of bare groundwire from a spare piece of cable and marrette this "pigtail" with the two ground wires inside the box, then attach the end of the "pigtail" to the green screw on the GFCI.
As an added safety step, I run the "pigtail" around the green screw of the outlet and the ground screw of the metal box you're working in.
The wiring then goes to the switch where the black wire can be cut, then each end is wired to the screws and the white wire is continuous to the fixture

I have a gfci/switch and need a 4 wire instructions. As none of the diagrams match what i have.

What device are you replacing... a switch or a outlet?

1) If you are replacing a switch with 3 or 4 wires?
That is either a 3-way switch, 4-way switch, or a DPDT switch and cannot be replaced with GFCI

2) If you are replacing outlet with 4 wires, then it can be replaced with GFCI combo.

3) If you are replacing ordinary single-pole switch, then you can replace with GFCI combo IF the box has a neutral wire

4) You can install GFCI protection on any circuit by installing GFCI earlier in the circuit.

20A125/250V wire diagram

I've copied instructions from an Amazon review.
worse than worthless and border on dangerous. Be forewarned, and allow some time to install it correctly; and don't expect any help from the included paperwork.


- There is no ON/OFF indicated on the switch or the instructions, so there is no way to know which direction is on or off. The picture included is upside down, and shown in the OFF position. If you install it with the switch on top, it will work intuitively with the switch up for ON and down for OFF. (Should be common sense, but doesn't say it anywhere, and the text on the device and photo suggests otherwise.)

In short, here's what the directions should say:

Before you begin -> Leave yellow sticker over top connections unless you want to add downstream GFCI protected outlets/lights - that's straightforward.

1) Strip all connections to 1/2", and use the holes on back of receptacle for direct connection.
2) Connect wires from breaker into terminals in back of switch/outlet. (Hot=Black-Gold; Neutral=White-Silver)
3) Connect white wire from light into extra hole next to the white wire from breaker.
4) Connect one short black wire from outlet into the hole next to black wire from breaker.
(this means all four holes are now filled)
5) Connect remaining black wire sticking out of receptacle directly to the black wire from your light.
6) Ensure all ground lines are properly connected.
7) Push into box, install cover plate and enjoy.

NOTE: This will result in the GFCI working properly, with no GFCI protection for the light. This is the recommended install, so that if the GFCI trips you won't be in the dark. If you want GFCI protection for the light as well, simply modify step 4 and insert the black pigtail into the hot terminal under the sticker.

The directions offer myriad ways to connect this, but are incredibly hard to decipher because the text does not agree with the diagrams. I believe that diagram B1 was the one that 95% of people will need...

Installing arc fault interrupter with ground fault

Question is vague. Arc fault and ground fault are slightly different.

Are you installing arc fault breaker?

Code says Maximum 12 boxes per circuit breaker.

Arc fault breaker and GFCI outlet in bathroom?
>>> do not connect this way.
Do not install 2 fault protections on same circuit.
Install the arc fault circuit breaker, and then remove bathroom GFCI, and replace with ordinary outlet, or switch-outlet.

How many outlets can be connected to a bathroom GFCI?
It depends on total boxes on circuit.
Count the boxes. Max 12 boxes per circuit breaker.

How many amps can be connected to 15 amp device?
15 x 80% = 12 amps
Electricians use 80% rule to calculate safe maximum

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.

I have cooper combination switch and gfci out let they gave directions for gfci outlets how do you wire it using the switch o control the outlet

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.

We are trying to install leviton combination switch in the old building and just two wires are coming out from the wall. how do we connect them to the switch? thanks

By two wires if you mean just a black and white wire then this is a switch leg and you cannot use this switch at this location. All you have here is the power coming in on the black wire an leaving on the white wire. The switch just breaks the flow of electricity. An outlet cannot be used here because there is no neutral wire. This is how a switch leg is wired. a8179fb.png
If you have something different post back.

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.

power coming in from the breaker box: black wire will go to line-hot screw, and the white wire will go to the line-white screw. the switch wires coming out of the back of the gfci- 1 will go to the load-hot screw & the other black wire will wire nut to the black wire going to the light. the white wire going to the light must go to the load-white screw.
