This answer was rated:

I have a 5 pair of wires in an outlet box. One is hot. The others are: to a separate outlet in a different room, to a light fixture, and the last two feed a light fan unit. Im connecting with a GFI. I have the hot pair connected to the line side if the Gfi. I have the rest of the pairs connect to the line side and they all get power. What I need help with is connecting a double switch to the GFI. The double switch is going to switch (1) the fixture (2) the light/fan together. How do I connect the double switch to the GFI?

AssuredElectrical :

Welcome. My name is XXXXX XXXXX would be glad to assist.

AssuredElectrical :

If I understand properly, you want to connect a double switch with power from the GFCI and use one switch to turn on a light and the other switch the fan/light combo.

AssuredElectrical :

Is this correct?

Customer: Yes that is correct. I've tried too many combinations....
AssuredElectrical :

ok, understand

AssuredElectrical :

all the wires are in the box that will hold the switch?

Customer: Yes
AssuredElectrical :

ok

AssuredElectrical :

do you know which wires go to the light and to the fan/light combo? so they can be separated?

Customer: Right now the switch isn't connected to anything. I just have the outlet, fixture & fan/light combo connected to gfi. All are on with steady power
AssuredElectrical :

ok

Customer: Yes
AssuredElectrical :

all the wires are white and black, no reds?

Customer: All white and black. No reds. Correct. Some bare ( ground) wires too. I have them tied together and connected to gfi ground.
AssuredElectrical :

ok, first, separate the black wires only, that go to 1. the light and to 2. the light fan combo

AssuredElectrical :

Leave all whites connected as they are now

AssuredElectrical :

Then you will connect a short piece of wire to the GFCI, that will power the double switch

AssuredElectrical :

Then connect the black wires to the light and light/fan combo on the other side of the double switch

Customer: One second.
Customer: When I conned the short piece to the GFI. Is that to either of the brass screws. Or one from each?
AssuredElectrical :

One side only, leave all white wires as they are now.

AssuredElectrical :

AssuredElectrical :

Look at that diagram

Customer: I have the a1 b1connected.
AssuredElectrical :

ok

Customer: Working on co to line side....
AssuredElectrical :

no problem, will await

Customer: Need to turn power off ...
AssuredElectrical :

ok, yes be safe

Customer: So the common on the switch is tied together And connected to Line side brass. Correct?
AssuredElectrical :

correct

AssuredElectrical :

that powers both switches

AssuredElectrical :

there may be a small tab that joins the 2 screws

AssuredElectrical :

if there is, you only need to connect to one of the CO screws

Customer: I'm wired but now but no power to devices connected to switch.
AssuredElectrical :

lets back track, something is missing

Customer: One sec.
AssuredElectrical :

ok

Customer: Did we loose chat?
AssuredElectrical :

i am here

AssuredElectrical :

can you see my post?

Customer: im ready
AssuredElectrical :

If you have power to the CO side, whatever is connected to A1 and B1 has to work

Customer: I'm on an iPad and the posts are hidden
Customer: Ok I see you now
AssuredElectrical :

I dont know how well the chat works with a pad

AssuredElectrical :

does the receptacle work?

Customer: Yes. Have green light on gfi receptacal
AssuredElectrical :

ok,

AssuredElectrical :

How many wires do have on the receptacle LINE side screws?

AssuredElectrical :

brass side? silver side?

Customer: I Have the out let, fixture and light/fan combo connected to the line on the silver load side of the GFI have the common and white wire from the hot pair connected to the line side. All white/silver.
AssuredElectrical :

Do you have all the whites stripped and twisted together with a wire nut, then a short piece jumper to the GFCI? All connections must be secure and only one wire to the GFCI screw

Customer: As far as the black the hot black wire to the brass line side and the black wire to the outlet (to the receptacal in the bed room to the load side.
Customer: But now if I switch both switches it tuna off the lighten have on connected to the outlet receptacle in the bed room.
AssuredElectrical :

Why are connecting the bedroom to the load?

AssuredElectrical :

Full Size Image

Customer: its in the box. Those wires are in the outlet. It's one of the 5 sets of wires.
AssuredElectrical :

is the switch not in the same box as the GFCI?

Customer: Yes it is
AssuredElectrical :

why are you saying in the outlet? what does that mean?

AssuredElectrical :

we have 1 double switch and 1 GFCI receptacle in the same box?

AssuredElectrical :

5 pairs of wires?

Customer: The box in the wall has 5 sets of wires. It has the GFi and double switch. I misspoke when I said outlet. When I say out let I mean the set of wires that connect to an outlet plug in the bed room.
AssuredElectrical :

Connect all the blacks together except the light black and the fan/light
combo black and add a short 6" piece of wire to them, use that 6" piece to
connect to the GFCI brass screw on the LINE side

That will be 4 blacks total in the wire nut.

Now connect all 5 whites plus a short 6" piece together with a wire nut.
Take the 6" piece and connect to the silver screw on the GFCI LINE side

Now, take the only 2 blacks left and connect to the A1 and B1 on the switch

Add a short wire from the brass side of the GFCI LINE side and connect
to the common on the Double switch.

AssuredElectrical :

That will make everything work

AssuredElectrical :

Something is crossed or not making connection right now.

Customer: stand by
AssuredElectrical :

ok

Customer: working on it....
AssuredElectrical :

ok, no problem

AssuredElectrical :

Did we lose you?

AssuredElectrical :

You were typing and then showed you off line.

Customer: Here.
Customer: Slightly lost.
AssuredElectrical :

ok

AssuredElectrical :

making sure

AssuredElectrical :

Let me post another picture, tell me where the last cable goes

Customer: @ 2:58!you said connect 4 black. Need to make sure I have the correct 4.
AssuredElectrical :

ok, hang on 1 sec

Customer: Hot, outlet from bedroom, are the other two a1 and b1 from the switch?
AssuredElectrical :

let me post a picture and you tell me where the last cable goes

AssuredElectrical :

Full Size Image

Customer: Ok
AssuredElectrical :

The one with the ???, where does it go?

Customer: I see. So the 5th is light/fan. I tie that in so I say I have 5 but really tie light and switch together.
Customer: I like this picture. Going to work on it now.
AssuredElectrical :

well, tell me what I am missing?

AssuredElectrical :

so I can make it complete

AssuredElectrical :

the one cable I do not have identified with a a name

Customer: Get rid of that. Call light/fan combo 4 and 5.
AssuredElectrical :

the light fan combo has 2 cables?

Customer: yes. I've tied them. When I switch it on I want them to com on together
AssuredElectrical :

Ok, just making sure I will change the diagram and show 2 blacks to the switch

AssuredElectrical :

This should be correct then, only 2 for constant power

AssuredElectrical :

Full Size Image

Customer: K. Let me try this. Need to remove and change a few things.
AssuredElectrical :

ok, no problem, just post when you finish

Customer: So just to make sure nothing connects to the Load side of the gfi.
Customer: ?
AssuredElectrical :

No, nothing is necessary to connect to the load

Customer: Back. Are you still there?
AssuredElectrical :

yep

Customer: Progress. All of the switches are working, outlet in bed room works. GFI isn't working. The green light doesn't come on and can't test or reset.
AssuredElectrical :

need to verify the connections, if the GFCI will not reset, the power is not getting to it. Maybe the white or the black wire where they connect to all the rest. The jumper wire may not be making contact.

AssuredElectrical :

Since everything else is working, it is probably the white wire not making contact

AssuredElectrical :

Hard to get good contact with a lot of wires, I usually separate them and make 2 large connections

AssuredElectrical :

I always twist the sires around each other, then use the wire nut

Customer: Ok. Trouble shooting now.
AssuredElectrical :

ok, understand

AssuredElectrical :

at least it is 80% now

Customer: Same issue. Could I have blown the gfi?
AssuredElectrical :

Well, anything is possible.

AssuredElectrical :

but it worked before, correct?

Customer: Yes
AssuredElectrical :

if you had a 2 lead tester, we could find out fast by measuring the screws for power

AssuredElectrical :

do you have a regular receptacle handy? swap it out for a test

Customer: Yes. Swap it for the gfi?
AssuredElectrical :

yes, only way to verify power without a tester

AssuredElectrical :

if the regular receptacle works, then the GFCI is bad, if it doesnt work, there is a loose connection

Customer: Do the two blak to lad go on each of the brass screws?
AssuredElectrical :

On the gFCI?

AssuredElectrical :

blacks should be on one screw on the GFCI, on a regular receptacle it doesnt matter

Customer: Sorry on regular. Doing now.
AssuredElectrical :

ok, you can put 1 black per brass screw

AssuredElectrical :

the 2 screws are joined with a small brass tab that connects them

Customer: Ok
AssuredElectrical :

I am here

Customer: Regular receptacle. Everything is working. The outlet tester shows open ground. It didn't show anything with gfi.
AssuredElectrical :

ok, sounds like the GFCI is bad then if the receptacle works now. Need to verify the ground connections though, may be loose

AssuredElectrical :

Loose ground will not stop the GFCI from working

AssuredElectrical :

GFCI measures the white and black wires only for differences

Customer: I didn't move the ground. Let me pull a new gfi from somewhere and I'll test. One question. If I ground only to gfi is that ok?
AssuredElectrical :

The grounds should all connect together and then jumper to the GFCI.

AssuredElectrical :

You need the grounds for the lights and fan for safety

Customer: Swapped gfi. Everything is now working. Thanks for the help!
AssuredElectrical :

Great Job, know it gets frustrating sometimes, been there before myself
