Question

Hot/grd reverse


I'm trying to install a new outlet for a dishwasher. I've tapped into a 20 amp circuit that feeds a backyard toolshed. I'm using 12/2 Romex and wired properly black to black, white to white and ground to ground. The new outlet doesn't work and I get a message from the little tester "hot/grnd reverse".

Using a test light, it appears the bare ground wire is hot. Could this be wired incorrectly from the panel????

Everything works in the tool shed, but the power seems to be routed thru another panel out there.

I would appreciate any suggestions?????

I think you need a voltmeter, if the ground is hot, how on earth is the breaker holding.

And how did you test that with a light, ground wire to........ground?

I just have a simple 2 lead test light, here's what I get:

Ground to black no light
Black to white dim light
Ground to white Bright light

Sounds like your common is hot.

You should be pulling a circuit from the panel your dishwasher, tying onto the circuit to the shed, is probably not a good idea to begin with.

The shed is hardly used and usually just for a light. I tapped in because the wire to it runs in the crawl space under the kitchen.

If the common is hot can I just wire white to black in my outlet?

You need to find out what happening with that circuit and fix it! Wiring black to white is not fixing it.

Absolutely NOT! You need to find and fix this problem.

What it sounds like to me is an open neutral and no ground.
Who wired this circuit?
Where does it originate?
Are there any splices or boxes in between?

Thanks to you and Jackofall1 for your replies. We've been in this house for awhile and have noticed some irregularities in the wiring. I think the previous owner might have wired the shed improperly. The circuit seems to originate at the main panel box and I don't see any other splices or boxes between the panel and where I tapped in. I'll have to look into it deeper..thanks again!

Have you taken the panel cover off, if you can do this take pics of it and post them. We can than see if we notice anything from the pics!
