This was a DIY tip in a magazine for an extension tap.

It looks like a short circuit; the wires are tied together on the outlet connector. It will blow the fuse or circuit breaker immediately--hopefully. -
Let's see:
1. Both wires connected to the same side of the outlet - would short out as soon as it was turned on.
2. No ground wire on a grounded outlet.
3. It looks like lamp cord feeding the outlet - would probably fry the insulation on the wires if any substantial load was placed on the outlet.
There's probably more.BillComment

Step 3 in the instructions are correct, but the picture is wrong. Like Bill said, no ground. I have a similar set up on an extension cord but it is wired correctly.Last edited by Pappy; 01-02-2007, 03:29 PM.Don, aka Pappy,

in addition to dead short and no ground, he mentions no attempt to
maintain hot-neutral polarity, and no mention of wire gauge. I'd also not use zip cord through a cable strain relief, I'd prefer to see a jacketed cable as well.

When we moved into our house, there was a flourescent fixture attached to one of the rafters. Whoever put it up used zip cord with a plug to provide power. It came down immediately.
Brings up a question. I have one tube-type fixture that's not directly over my saw but could be in the shrapnel path if something went badly wrong. How impact-resistant are the plastic lenses in inexpensive, big-box fixtures, or are there better quality fixtures I should look into?Comment

CabMan,
What magazine?

OK. don't laugh. It was in Make magazine that I was raving about in my thread about Rocketman.

You can buy a cover for the tube or buy shatter resistant tubes. I work in a food manufacturing plant and all of our tubes are either sleeved or are shatter resistant. The shatter resistant ones can be dropped and will break but there is no loose glass. The sleeved ones can lose the end caps if they are not taped in place.

You don't run stranded wire to an outlet or switch either, you use pigtails made from solid wire of the same size.Comment

Actually that is the lazy electricians way to do it. It's just another reason why electrical contractors don't like to use stranded wire. The bottom line is they don't work with it properly. The preferred way it to tin the stranded wire and use the screw terminals or use a crimp on connector solder it and use the screw terminal.
Using the pigtail method leaves you with and extra termination which is just one more place for a possible problem. NEC should do something about this poor method but hasn't yet.
Stranded wire is a superior product and creates a superior circuit when used properly! But it is more expensive and requires more labor/time to install.
Opinions are like gas;
I don't mind hearing it, but keep it to yourself if it stinks.

Just goes to show, you can't always believe what you read or see.
Having spent most of my life as a technical illustrator, it's plain to see that there were a series of failures here. No EE, no technical editor, the tech writer wasn't acquainted with the NEC code, and the illustrator didn't have a clue. Obviously the publications manager was on vacation and neither the proof reader nor anyone at the publisher had ever seen the inside of a circuit box.
It just proves the point that you'd better darn well know what you're doing in the first place and when NOT, hire a qualified person.
Shocking!

All you eagle eyes did find what was wrong. What I found disasterous was the picture showed the wiring wrong, the text did say "on each side". Since most people are pictured oriented, in technical information the text should back up the picture. It would have to be assumed that one could just look at the picture and get the data right. In this case it would be dangerous and "shocking"
As Loring pointed out about the polarity, I would suggest that in a DIY type article that distinguishing the polarity by looking at the wire should have been brought out. If the suggestion was to use zip (lamp type) cord, that most have a smooth jacket on one side and a ribbed jacket on the other. Or, as in some the actual strands may have a color thread running through, or some faint lettering along one side.

Actually, now the lazy way it to strip the insulation and poke the solid wire through the little hole on the back. No fumbling with screwdrivers and no pigtails.Actually that is the lazy electricians way to do it. It's just another reason why electrical contractors don't like to use stranded wire.
