I don't think so. The three wires means it was either a three-way switch for different points of turning off lighting, or was once the old kitchen 15a/15a dual powered outlets (where top and bottom each had their own 15a power wire with common neutral and ground).

The extension cord is powering two different circuits from the looks of it, and he has crossed polarity on one of the circuits.

They probably lost the power from which ever BX grouping was the original source, and just back fed the circuit power to give juice to whatever is back down the line.

I'd like to envision it as some dummy accidentally cut the wrong line at some point, and this was some lazy rear end's way of getting power back down the line.

Oh god I need to study up my electrical stuff. Assuming the wires are providing what they're supposed to, isn't he just basically shorting out his 120V?

How do you guys not have a fire extinguisher nearby if you're doing hot work? Do you know know if the welders are filing hot work permits with the safety officer? What exactly is it you do? You must be working with some lovely welders if they go into a room with oily rags and still think its safe enough to work.

If you look close he's got hot on the left and neutral on the right, so he's not shorting or locally completing anything. I'd wager whatever 3 way set up was ripped out and he jumpered it together in the extension cord receptacle to give ostensibly one complete circuit (no ground cause that's for pussies) powering the extension cord and whatever is connected to that.

Quick question - how do you plug a device into a male ended extension cord end? :v:

I think the cord is providing the power and he has two wires being FED from the extension cord. The only time I've seen a male ended extension cord hookup is when someone was back feeding a generator to run a hard wired motor from 110V instead of the generator (blown in insulation company not wanting to pay gas on their generator).

I think my gut was trying to warn me about that little detail and discounted it because who'd be insane enough to do that even though the other way doesn't make any more sense when you put it that way.

I only know since I sorta did something similar when I had a sump pump die in the middle of the night. I tired to make it as OHSA/not redneck as possible, but I certainly summoned some MacGyver in myself.

I took apart the switch mechanism, soldered the leads to an old extension cord, plugged the male plug into a spare non-powered outlet in a temporary hobby box, and then plugged my pool cover pump into the second outlet.

So power fed old pump, switched kicked on, power sent to outlet that spare pump was hooked to, and ran the pump until the floater dropped and shut off power to the original pump. :smugbert:

After confirming the system worked, slept like a loving baby until the morning when I could get a new one.

Yeah. Here, take one:

That reminds me of something that happened at work about 15 years ago. A maintenence man was welding in some air duct work. Now, this is an auto carpet factory and when the rugs are heated a lot of smoke and vapor can be given off and between that gunk that had accumulated from the smoke venting through and carpet fuzz that gets everywhere, the inside of the duct had a build up of flammable crud.

Which, of course is ignited by the welding.

Now, Mark did think ahead. He had a small fire extinguisher with him that he would once in a while use to put down the fire so he could weld some more. Smart man, right?
Unfortunately, either the extinguisher ran out or the fire got too big to control and he then called for more fire extinguishers on the radio. So, at this point we had a handful of maintenance guys with extiguishers that would take turns putting out the fire in the duct, which would start back up as soon as the chemical cloud drifted away.

When they emptied the eleventh one they finally decided to call the fire department.
To this day, the local fire dept. still uses this incident as an example of what not to do when giving fire safety lectures.

First one:

HF + H2NNH2 + Heat (for good measure) + shaking = ???

(Are there any chemists here who know what mixing this would cause?)

Well, its not well written, as compared to actual literature, but its pretty well written given that the author is a chemist. Geez, what do you want; loving prose *and* equations?!

Also, read Max Gergel's Excuse Me Sir, Would you Like to Buy a Kilo of Isopropyl Bromide? for a pretty much non-stop workplace safety incidents, also written slightly poorly, by a chemist.

They're both available at sciencemadness.org as PDFs or you can pm me for an epub version of either.

Well, to be fair, the duo do live in the most war torn section of Ukraine and most of their videos have the steady sounds of shelling in the background, and they've had videos talking about how so many neighbors have had their houses destroyed in the middle of the night. If I were living like that, doing dangerous things with electricity, fire, and magnetrons would probably be one of the safer things to do.
