I does'nt look at the ground at all. The GFI will monitor the current flow in both hot legs. If the current flow differs between both by 5 milliamps or more, the difference is assumed to be leaking to ground, and the CB will trip. I'm not a licensed electrician however, so you should double check my answer.

Low voltage coming from outlet

1) Copy following links:

2) Move hot wire to different, same-amp, circuit breaker and see if problem persists.
Look for loose quick connect on back of each switch and outlet on circuit, including GFCI, replace GFCI.

3) Add comment and say what you find.

Need to install a 2pole 20 amp gfci breaker in an ite bq panel. what are my options as I don't think they make this breaker in type bq?

Hi Pauline, I'm an electrician and can help you with this problem.

The only breakers that are permitted to be installed in any circuit breaker panel are listed inside the door on the label. Introducing any other type or brand is a fire hazard and a code violation. The national electrical code is very clear on this.

If you need to provide a GFCI protected circuit from this panel, you'll probably need to install a smaller panel from this panel - called "sub-panel" of a brand and type that will accept a GFCI circuit breaker. This is done by purchasing a 2P20A GFCI breaker and a smaller circuit capacity / ampacity panel rated for the same voltage as the main panel. You'll also need a ground terminal strip for this panel, too. A 60A main lug panel with 8 or more circuits type panel might be a good place to start. Purchase a 2P circuit breaker with an ampacity no greater than the sub panel is rated at - in my example - a 2P60A would be right. You may use a smaller breaker (2P40A or 2P50A) if you wish - but none greater. Mount the sub panel in a location near the main panel. Remove and discard the bonding screw or lug (if provided and installed already) that may connect the neutral bar and threaded into the panel enclosure. Install the ground terminal strip you purchased separately into the threaded holes provided for it inside the panel enclosure. Install the Ground symbol sticker next to this bar. Run a 4 conductor cable, pipe & wire, etc. feeder sized for 60A based on the location, temperature, etc. between the main panel and the main lug panel. Terminate the cable the sub panel end as follows: black & red or "hot" wires into the the lugs that are connected to the bus bars, white or "neutral" to the neutral bar and the bare or green "ground" wire into the ground terminal strip you installed previously.

Next terminate the other end of the cable. Power off the main panel completely. Terminate the white neutral and the bare or green cable in the neutral bar in separate terminals. Install only one wire per terminal - do not "double up" wires under a single screw. If there is a separate strip for neutral and separate strip for ground - maintain neutral wires to neutral strip and ground wires to ground strip. Also, do not intermix ground and neutral wires in the others terminal strips! Install the 2P60A breaker in an unused space in the main panel. Connect the two hot wires to the breaker terminals. If using aluminum wires, be sure to clean and apply oxide inhibitor to stripped ends of the wires.

Now, you should have a smaller panel with 8 or more empty spaces for circuit breakers that will become live when the 2P60A breaker is in the main panel is turned on. With it still off, install the 2P20A GFCI breaker in the new sub panel. Run your circuit(s) to this panel. Connect them as usual - but any neutral and ground wires installed must be terminated in their respective terminal strips. As mentioned above, never install them in the others strip.

If installing in a 3 phase environment - you may wish to install a 3 phase sub panel so that 3 phase loads can be connected to it. This will require a 3P60A breaker and 5 wires instead of 4 wires to be run between the two panels. The additional wire would be a hot and blue in color for a 240/208/120 panel.

I hope this helps & good luck!

I have two wire in box cant get it to work switch/gfi combo

If I understand correctly you are replacing ordinary switch with switch-plug-GFCI device.
And one cable enters the box, and the cable has 1 black and 1 white and 1 ground wire.

To correctly wire combo GFCI device, you need a Neutral wire.
If your switch box has 1 cable, then it does not have a Neutral.
The neutral is required for GFCI operation, and also to power new outlet.

To test for Neutral wire:
Separate wires for testing.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot line wire from breaker box.
Hot is identified.
Test Hot wire to all other wires inside box, except bare ground wire.
Tester lights up on Neutral wire.

> If switch box does not have Neutral, then device cannot be wired correctly.
> If you do have a Neutral, then open following link for correct wiring of device:

My out let has 2 black wires and 2 white wires and no ground. The out that I purchased has 2 black wires on the back I know where the white and black. Wires. Go from the wall. .**** what do I do with....

You purchased a GFCI outlet.
You posted under GFCI combo switch and receptacle.
If you have different device, then add a comment.

On back of device are markings that show Line and Load.
These markings are associated with screws on device.
Black Hot wire connects to Brass-colored Line screw.
White Neutral wire connects to silver screw located opposite Line screw.
If you don't know which wires are Hot and Neutral, the testing steps are shown at bottom.

Your other two wires evidently go to a light, fan, or motor that is operated by the switch.
This is where the two wires that stick out of GFCI device are used.
Your Black Load wire connects to one wire, and your White Load wire connects to other wire.

Finally there are 2 screws left on GFCI device.
These screws are used if the Hot and Neutral wires go forward to another switch or receptacle box. This would require another Black and White wire in the box, and all devices from the GFCI forward would be protected by the GFCI.
As you know, the way electric circuits work is a Black Hot and White Neutral leave the circuit breaker box and travel to a junction box. From the junction box, the Black Hot and White Neutral travel to the next box, and then the next box, and so on until the last box is reached. Each box contains a switch or plug or combo device or a light fixture. In your case, the Black Hot and White Neutral may not send power forward to another box, and may just be a switch box that has a single wire to the light fixture, and that is the end of the circuit.

How to test for Hot and Neutral wires:
Separate your 4 insulated wires.
Turn power ON.
Test each wire to bare ground wire.
Tester will light up on Hot wire.
Now Hot is Identified.
Test Hot wire to each other wire in box, except bare ground.
Tester lights up on Neutral wire.

Trying to hook up a pilot light switch to a gfi recp not having much luck with getting it to work properly i got 2 conductors from the panel and 2 conductors going to the gfi recp and on the switch i have...

It is unclear what pilot-light-switch is supposed to turn on-and-off.

Option A) pilot-light-switch is going to turn GFCI on-and-off
Option B) pilot-light-switch is getting power from existing GFCI circuit, and switch controls another Load (light, fan or motor) located elsewhere.

Add a comment at any point.
Bare copper wire always connects to green screw.

1) I have a Cooper pilot-light-switch in my office.
Black Hot wire from breaker always connects to dark-colored screw(s).
White Neutral wire from breaker box connects to silver-colored screw
Wire going to Load (light, fan, motor) connects to brass colored screw.

2) Two things happen when pilot-light-switch turns ON:
a) Pilot light turns on. This circuit is powered by black Hot wire, and circuit is complete with white Neutral.
b) Brass screw that had no power, is now powered.

Hot from breaker always connects to brass-colored Line screw
Neutral from breaker connects to silver-colored screw that is opposite Line screw.
If other switches and plugs are going to be protected by GFCI, they connect to brass Load screw and to silver screw that is opposite Load screw

Option A) You want pilot-light-switch to turn on GFCI receptacle.
a) Wire pilot-light-switch as described above
b) Black wire from GFCI line-screw connects to brass screw on pilot-light-switch.
c) White wire from GFCI silver-screw-opposite-line-screw connects to any white Neutral.

Option B) Pilot-light-switch is getting power from GFCI receptacle AND you want pilot light switch protected by GFCI.
a) Black wire on pilot-light dark screw connects to Load screw on GFCI
b) White wire on pilot-light silver connects to silver screw on GFCI that is opposite Load screw

Option C) same as option B except pilot-light-switch is NOT protected by GFCI.
a) Black wire on pilot-light dark screw connects to Line screw on GFCI or any Hot wire
b) White wire on pilot-light silver connects to silver screw on GFCI that is opposite Load screw or to any Neutral wire

We have a 2 new 956i treadmills why don't they run with a GFCI or will they?

Most treadmills are designed to use the ground to disperse extra static energy - the ground on the GFCI is used to detect fluctuations in the current flow from the hot to the neutral side. The difference in current flow can be as small as 5 milliamps. When the ground pin on the GFCI detects this fluctuation, the ground will open the circuit. This is why it is not recommended to plug a treadmill into a GFCI.

I installed the above gfci with the pigtail side adjacent to the neutral bar, contrary to intructions. The gfci trips immediately when power is turned on the gfci is switched on. What could be wrong and...

1. Did you connect the neutral wire (white) from the breaker to the neutral bar?
2. Did you connect the circuit neutral wire (white) to the circuit breaker. If there is a neutral load the load MUST be connected to the breaker no to the panel neutral bar.
3. If this is a 50A load, what is the appliance connected to the circuit? If it is a range, quite often the newer ranges have a ground wire connected to the burner mount. A small current leakage in the element can trip the GFCI. Check each element (with power off) from the wiring terminals to ground with an ohm meter.

Gfci breaker for spa

gfci's are designed to trip if they receive voltage on there ground/neutral side, therefore my vote is for Smithbrother I would say there is probably a partial short somewhere in you system.
