I replaced an old style receptacle with a GFCI the other day. But now i am wondering if i replaced it correctly. Hook up gfci outlet 4 wires were 2 black wires, 2 white wires, and a ground.

I inserted the 2 black wires into the black wire LINE side, and the 2 white wires in the white wire LINE side, and hooked up the ground. An appliance will work when i plug it into the GFCI receptacle, but i am unable to trip the receptacle by pressing the test button. Join Date Nov State CAL Posts 2, You have not wired it correctly.

Of the existing wires, kaleidoscope dating sim walkthrough pair a black and a white are the source or line voltage from the panel. The other pair is a cable which carries the voltage to another receptaclepossibly nearby but not necessarily. There should only ever be one black hook up gfci outlet 4 wires one white connected to the LINE terminals of the GFCI.

You need to determine which pair is which, and the second one should be connected to the terminals marked LOAD. You might need help from an electrician so sort this out. It seems the GFCI should have tested OK, even though your downstream receptacle was not protected, so there may be another problem.

The above connections will give you GFCI protection at the GFCI receptacle only, which sounds like what you want, and is appropriate in many situations. However, if you want GFCI protection at any downstream receptacles, then you need to connect the power wires to the LINE terminals and the downstream wires to the LOAD terminals, which is what tough was eluding to. Verify that you have the black wires on the LINE terminal brass connection and the white hook up gfci outlet 4 wires on the LINE terminal silver connection.

Then use a two wire tester or an analog meter and check for power between the black wire and the white wire, between the black wire and the ground wire, and between the white wire and the ground wire. Post back with the results. You can also try a brand new GFCI receptacle. Ok, apon further inspection of my fuse box labeling, the fuse for the receptacle goes to the gfci receptacle, then some outlets for the outdoor plugs.

So, i see a set of wires coming from the top of the wall, and hook up gfci outlet 4 wires set of wires from the bottom of the wall. I can figure that one set either is from the fuse hook up gfci outlet 4 wires, or is the load wires for outside. Can i try to put one set in the line side and the other set in the load side, and hook up gfci outlet 4 wires if it is the correct set through process of elimination?

If it isn't the correct set the first time, would that be bad? An old GFCI which you shouldn't be installing anyway will work but improperly if you get the wires reversed. It will NOT trip, but will provide power to the receptacle itself and may provide power downstream. A new GFCI will not work when the LINE and LOAD wires are reversed. However, do not guess. Use your two wire tester or analog meter to figure out which are the line wires and which are the load wires.

You should have at least a two wire tester if you are doing any electrical work. They are cheap and invaluable when you have a problem. If you do not have one, buy one. If your GFCI is not new or is more than a few years old even if never used then buy a brand new one. Even if you don't have a tester and foolishly refuse to buy one, you can still figure this out. Connect one set of wires to the LINE inputs of the GFCI. Restore the hook up gfci outlet 4 wires and see what happens. If you get no power at all, then try with the other set of wires connected.

It even trips when i press the test button. Thanks a lot everyone, I learned a lot today. I feel incredibly relieved knowing that everything is wired properly. I'm glad you have everything working.
