Electrical Problem - Need help

hello all, i need some help.

i removed an outlet to install a GFI. there are two wires (2 black/2 white) and a ground. well both blacks are hot.... i thought one should be the line and the other the load. how do i wire up the GFI? just nut up the unused wire?? thanx

It is extremely unlikely that both black wires are hot wires. Only in a very strange (and incorrect) situation would this be the case.

How did you determine that both black wires were hot?

One other question. Is your intent to provide pass through protection to something else on this circuit? If so, what other device or receptacle did you want to provide pass through protection to?

If you did not want to provide pass through protection to something else, then it makes no difference which wires are line and which wires are load.

thanx for the reply. i tested both blacks with my electrical tester and the light comes on for both.

there is nothing down line that needs protection, so can i nut up one of the wires and just use the remaining?

No, you cannot put a wire nut on one of the wires. If you do so you will eventually find that something else in your house doesn't work.

Both wires are not hot. Your testing method is wrong.

How are you testing for power?

What are you using? A light bulb tester? A tick tester? Do you have all four wires completely disconnected when you test? What is your method?

the power is on. the four wires are sticking out of the electrical box spread apart from each other.

i am using a light bulb tester. a little test light.

i am getting "hot" for testing both blacks against the whites and both blacks against the ground wire.

Are both of these wires connected to the same circuit breaker? Did the old receptacle have the tab broken on the side with the gold screws? Either you have a duplex on two seperate circuits or someone ran a redundant wire.

ahhhh. yup, the top wires are on one circuit breaker and the bottom are on another breaker. what to do? pick one and nut the others up?

i couldn't tell anything by the outlet that i removed.

thanx

Is this in the kitchen and are you in Canada?

If yes to both you cannot replace this receptacle with a GFI. You must use a two pole GFI breaker.

Unless you are using a ton of appliances in your bathroom it would probably be alright to cap off a set of the wires and use the other for your GFI. The alternative is to change the breakers to GFI breakers and replace the receptacle you took out. Or replace the existing box with a 2-gang old work box, and install 2 GFI receptacles.
