Me and the GF and the dogs all wear our tin-foil hats 24/7. We are safe from Whirlpool and the waves coming from Zilactron 5.

If someone has sufficient knowledge and is mechanically inclined, they could, under the supervision of a professional electrician (after having read and understood the step-by-step instructions of a project book) perform the wiring of an apartment. There are so many things that could go wrong, and the lights may even work initially. But life-threatening hazards may exist in the wiring, which one day might cost life or property!!!
I like to think that I am posting here because I am seeking the advice of professionals. This is a classical case of screw-in-wire that was easily remedied by the fine folk on diychatroom.com, and not one that needs to pull a permit from the city.

Besides, what sort of life threatening hazards could possibly exist in an ungrounded, cloth insulated 2-wire wooden house built in the 50's? Anyway, if I can paint my own house, I figure I can rewire this sucker.

For you own personal use, or in case anyone missed it under the original post (up there, after Warning), the owners/moderators or this board have said what you just said, several times over. I think we get it, Mom.

Right, because the two are completely synonymous.

I sincerely hope that this is a joke.

Keep the living room breaker off until this issue has been resolved. Someone is bound to be electrocuted by this situation, and there could be a fire due to the damaged wire in the wall.

Again, I hope this was a joke. I cannot imagine anyone actually being uninformed/naive enough to make a statement like that.

By that thinking, I should be able to climb Mount Everest because I can ski !

Just because he lights go on doesn't mean they were done right.

Reversed polarity can do major damage, especially when combined with bootleged grounds.


Call a professional today.

Haha, or in my case where the previous owner used a ground wire for the neutral in a switch loop setup to add on another light. Light still comes on, is it safe? NO way!

So it was a screw in the wire. I nailed it! (No pun intended.)

As for the rest, I think he was being facetious. Or at least, I'm going to believe that in my little happy world, for now.

DO YOU KNOW WHAT HAPPENS TO THE HUMAN BODY WHEN IT GET ELECTRUTED? Burns where contact was made. Also it is like getting into a microwave, you get cooked from inside out. I have personaly seen some die that way, he lived about 7 hours smelled like burnt steak, SOMETHING ONE CAN NEVER FORGET. DO NOT PLAY WITH ELECTRICITY WITHOUT GETTING SOME EDUCATION ON IT. TAKE A CLASS OR GET A PART TIME JOB WITH A LOCAL CONTRACTER TO LEARN.

While I agree with the sentiment, the delivery is a bit ironic.

See, now I thought the crack about wearing foil hats would have set the stage. I guess I overestimated some of yous' grasp on dry humor.

None the less, I just got done mudding the wall back together. The culprit was about a 1mm contact to the hot wire from a mounting screw. I cut off the circuit, cut out the rock, backed the wire out, carefully stripped away the outer insulation, taped the black wire up and then taped everything around that to make sure it was good and wrapped. Cut a piece of sheet-rock, screwed it, mudded it and am waiting on it to dry. While I had the hole cut in the wall I made pencil marks outlining the wires I could see and the studs so I would have better aim the second time around.

Now, in all seriousness, let me know if I did something incorrect here. I will check back in a few. I have to go swap out a 30amp breaker for my dryer.

when you're all done with mudding the wall... do 2 things for your own good

1. run a dedicated circuit, microwaves use a lot of juice.

2. get a $10 - 3 prong plug in led circuit tester and use it every time all the time...lightning can strike twice

Before you risk any more appliances check the circuitry first with meters or light bulbs.

Meters make sense, and were used, but given the fluke accident that was a screw in a wire, I don't think anything would have registered. The circuit itself was fine. It was the "live" MW mounting bracket that was the issue. I would like to know if there was a safe way to test this. Unfortunately it never crossed my mind to wire a light bulb into my MW cabinet then randomly start touching it to grounds. It was just one of those things, right?
