Male to male USB type-c cable, DuPont connector, widdowmaker cord (I don't care that some fools think male to male extention cords are dangerous, it's just a little electricity)

[–] ZILtoid1991@lemmy.world 8 points 1 year ago (2 children)

USB-A to USB-A cables are just one "I need to transfer data between two computers" and one tech illiterate away from blown PSUs.

[–] MachineFab812@discuss.tchncs.de 3 points 1 year ago* (last edited 1 year ago) (1 children)

Maybe if they are making their own. Such cords sold at retail will either have the power leads disconnected, or a chip like USB C uses to only connect power as negotiated between the devices.

[–] ZILtoid1991@lemmy.world 2 points 1 year ago (2 children)

Some cheapo and janky USB devices use the USB-A to USB-A cables, without the power disconnected.

[–] BorgDrone@lemmy.one 2 points 1 year ago

I have a cheap USB to IDE adapter from Aliexpress that uses one of those. The fun part is that you can’t ever replace the cable because they should not be made and no reputable brand will ever sell one.

I've found those. At a local store in Baghdad. Never seen such make it to Best Buy, Target, or even Radio Shack. Might as well buy a USB Killer from AliExpress and skip the "double-ended" non-sense.

See, even Intel makes them so it must work (ignore the fact it is intended for debugging)

[–] marretics@discuss.tchncs.de 11 points 1 year ago (2 children)

Funnily enough we had such a cable at home for reasons unknown to me. Then of course the inevitable happened: I was electrocuted by it. I'm fine, but I can definitely agree that such a cable should not ever be made, whatever the reasoning, just don't do it.

[–] LapGoat@pawb.social 4 points 1 year ago (1 children)

if you have a generator and your house has no electricity, you can power your house by plugging a generator into an outlet.

I am not an electrician and dont know how this would safely be done, i assume your house would need to be disconnected from the grid or something.

[–] pftbest@sh.itjust.works 7 points 1 year ago (1 children)

There are cases when electricians working on the street to restore power get shocked by some house generator feeding power back to the grid.

Naughty plug survivor 🫡

[–] popemichael@lemmy.sdf.org 10 points 1 year ago (2 children)

I made one of these when I was young, poor, homeless, and imminently dying due to being swiftly being frozen to death (with bone tumors coming in second place in the death race). I was able to get an abandoned metal shead with a small heater working quickly in a sudden ice storm using on hand parts and a pirated "outside" power line.

Outside of a significant situation like that... it's not a good idea

[–] hihellobyeoh@lemmy.world 6 points 1 year ago (1 children)

I mean he'll, in high school residential electricity class we had one of these for testing our walls, one time it burnt out a wire and the teacher only let me fix it as I was the top of the class, mind you we were only a class of 6 so...

[–] popemichael@lemmy.sdf.org 2 points 1 year ago

In those situations, that is the best class sizes for electricity tomfoolery, sprinkled heavily with bravely, and a side of youth assumed immortality.

It is also a good class size to swiftly move bodies, of things get too bad.

I had a similar sized class when I apprenticed as an electrical worker via "future farmers if America" funding.

I learned so many good ways to fix things correctly, and three times that number in "bad" ways to fix things.

Guerrilla learning method with pratical daily needed subjects is SORELY missed now-a-days.

That’s badass, glad you made it and wrangled the naughty plug

[–] tacosanonymous@lemm.ee 6 points 1 year ago (3 children)

I can’t think of a not insane reason anyone would need one.

[–] King_Bob_IV@startrek.website 5 points 1 year ago (3 children)

People want them around the holidays because they hang their lights in the wrong direction and end up with 2 female plugs where they needed one to be male.... So the want the danger adapter because they are not wanting to take anything down

[–] tacosanonymous@lemm.ee 8 points 1 year ago (1 children)

I absolutely do not consider that to be a sane reason.

[–] King_Bob_IV@startrek.website 3 points 1 year ago

Nope should anyone.

At work, I have a freezer with a couple thousand dollars of product in it. If I lost power and only had male plugs to jerryrig the generator into the circuit, I would. BUT only after turning the mains off and padlocking the panel shut. I didn't have to do that as I just wired the generator directly to the freezer after disconnecting it from the mains.

[–] Agent641@lemmy.world 3 points 1 year ago (3 children)

Wait, an electrical outlet can be an inlet too?

Mains outlets aren't smart, they're just wiring with contact points. If you feed power into an outlet, it'll energize the circuit it's on, which is a bad idea if your mains circuit breaker isn't off.

[–] jjagaimo@lemmy.ca 5 points 1 year ago (1 children)

Technicaly it is connected through the breaker so you could only supply as much to the rest of the house as that breaker can pass. Not ideal or the proper way of doing it though. Also the reason to disconnect from the grid is that you could start feeding downed power lines, and if line workers go out to work on the lines they can be electrocuted. Also, theres no telling when power will return. There should be a separete input for the generator and a transfer switch to switch between the generator and grid.

[–] Natanael@slrpnk.net 3 points 1 year ago

There's a reason why home battery storage systems needs to be connected to the breaker panel. You route power through it. When the batteries aren't needed then it's just a dumb relay for grid power. When you're drawing power from batteries it disconnects the grid.

Only a few industries ever draw power both from grid and local power sources at once (during peak load) and they route all the power sources through a power distribution system which prevents backfeeding.

[–] DogWater@lemmy.world 4 points 1 year ago

Yes. It's called backfeeding I believe.

[–] glizzyguzzler@lemmy.blahaj.zone 3 points 1 year ago* (last edited 1 year ago) (11 children)

You can run something like a house off a generator with one if the main breaker is off; in an emergency and the operation reasonably well planned out (don’t overload wall lines you plugged into, etc.) it might be a net benefit. On the reg is asking for death cause there’s safe ways to do it that sane people would plan for on the reg

No frotting the electricity

Sound it instead.

Why do people want them so bad tho

[–] CobblerScholar@lemmy.world 3 points 1 year ago

Christmas lights they accidentally wrapped backwards with the male end of the string all the way at the top of the tree

[–] chiliedogg@lemmy.world 1 points 1 year ago

I've used them in a pinch to run a circuit on a generator, but it can be really dangerous in several ways.

You flip the breaker off and plug the generator into one of the outlets on the circuit using one of these and it'll power the rest of the circuit.

But pretty often the generator will put out a lot more amps than the wire in the wall is designed for, and you've bypassed the breaker. If you hook up too many devices you can draw too much current for the wires and start a fire.

[–] agegamon@beehaw.org 1 points 1 year ago* (last edited 1 year ago) (3 children)

They want them because they're being lazy/cheap. No, seriously. They're called widowmaker cords for a reason, but inevitably some muppet with two plugs and some wire will come up with the brilliant idea that one of these will work for.

One really sneaky and dangerous place these get made are generator backfeed cheater cables for houses. You see them in RVs, Xmas lights etc too, but generator backfeeds are super dangerous because they're also juggling two potential power sources. A backfeed is where a house/building is disconnected from the grid just by flipping off the main panel breaker, then it's "backfed" by a generator going into another breaker in the panel. Usually, without any type of safety interlock to keep the mains voltage off when the generator is on, or vice versa.

Afaik, this is illegal per housing code almost everywhere that I've seen, but still every now and then some yahoo thinks "wait, if I make a two-ended cable and put a receptacle on the house, I can remove the generator easily without any of the expensive safety crap!" And then grabs a live male plug when they fuck up and didn't shut off the generator or mains voltage...

Just because a cable like that blows y'alls fuses?!

It's pure fire!
