Help installing GFCI outlet
 
2 Attachment(s)
Hello,
I'm trying to install a GFCI outlet in my kitchen, but something's not working. The outlet's in the middle of the circuit (4 wires + ground). The first thing I noticed was that when I went to determine which were the load and line wires, I had to use the ground wire. If I used the white wire, the circuit tester showed no connection.

So after determining the line wire, I hooked it up, but nothing seems to be working. Test does nothing, reset does nothing, and I only measure voltage between the line wire and the ground terminal.

Any suggestions? Thanks in advance.

sounds like you lost the neutral some where,open up other receptacles on the couter top and see if there is a loose connection.

If it is an older home ...there could be a fuse blown . Some knob & tube wiring I found in a turn of the last century home had screw in fuses on the neutrals in some sub distribution boxes. You may have inadvertently blown one during installation.

Thanks for the replies. The thing is, though, if I reinstall the old non-GFCI outlet, it works just fine. That would seem to indicate that a least no other fuses have blown. Could the neutral still be lost if the old outlet will work?

your wiring the gfi wrong if the old recep works, you need to get a meter and find the line and load, then hook up to the gfi correctly. Take your meter and find 120 volts on one set of black and white wires, the other set is the load. (if you even want the rest of the circuit GFI protected)

IF YOU ARE getting 120volts from old receptacle the GFI receptacle is probably bad,I have bought new ones and sometimes they do not work.You also need to make sure you were using the neutral from the line side coming in .

Well, I was using a circuit tester, not a meter, but the circuit tester showed nothing between either set of black/white wires. It was only when I measured between the black wire and ground that the circuit tester showed a connection.

Are you sure you have the matched set of wires from each cable? If you are testing from one cable's black to the other cable's whit, you won't get a reading. And a GFCI won't work either.

Doh!! Turns out I had the neutrals swapped. For the life of me I can't see how, because when I reinstalled the old one, I'm pretty sure it was using the same pairing as with the GFCI. Oh well, it works now, so thanks y'all for your help!
