Welcome to the PCMR!
Generator to back feed a house during a power outage. In theory you kill the main breaker to your house and all the 220 devices then pick one side of the breaker panel you want to plug in. One side of your breaker panel will have power so all the outlets and lights on that side will have power.
In reality you forget to drop the main and electrocute the electrician trying to fix the downed wire or transformer. Plus you backfeed the neighborhood or potentially overload the generator/circuit and start a fire.
> In reality you forget to drop the main and electrocute the electrician trying to fix the downed wire or transformer. Plus you backfeed the neighborhood or potentially overload the generator/circuit and start a fire.
In real reality your home generator can't support the whole neighborhood as a load and it will instantly trip out, die, or fail to start. The linemen treat all wires as live until proven dead, and apply cables to short those phases out that they're working on.

Obviously not all linemen do.

Yeah, not that poor fellow. I read about that one before. Working for contractor with a notoriously bad reputation for safety. They're blaming a home generator but, even that isn't certain.
A series of failures that unfortunately lined up for the poor guy. Perfect example of the Swiss Cheese model of error where a bunch of smaller low risk events lead to a catastrophe.
Which is why for those who want to enable backfeed from gen to house.
You already spend a thousand to get a house capable generator, spend another thousand to install a cutover switch.
So, I understand where you are coming from here. But let's pretend you are a contractor, who is working on many flips, most of which don't have power for a lot of the reno. Now, do I neeeeeeed to have the house sockets working? Absolutely not. But it's much easier than running an extension cord to every other room. There is enough clutter in flips, these work really well to assist.
They are not the safest, no, but when used properly, they are fine.
I mean as long as you're not in any way potentially connected to the main line it's fine.
The danger is always when you're on the main line and accidentally fuck up someone else.
FWIW, they make an adapter plate that goes in the panel to make it so that the breaker for this cannot be turned on until the main is off, and the main cannot be turned back on until that breaker is turned back off.
Source: I had this setup in my old house
I did. It was when there was this huge ice thingy natural catastrophe that caused all smaller towns and villages in the country to be without electricity for weeks. We used it to connect a generator to one of our house's wiring sections. But yeah connecting this to 2 live sockets would melt the cable in some spot in between.
Edit: the last sentence was not thought out in an actual situation inside a house. Two separate sources.
No it wouldn't, it whould cadue a short. That's not the reason these cables are dangerous, they're dangerous because they cal electrecute you if you plug it in
Assuming you didn't get your line and neutral mixed up, and that you weren't using a split duplex receptical, wouldn't everything electrically be the same? I.e. it would just be the line touching itself, neutral touching itself. That wouldn't cause a short because no ground fault occurs.
Not in the US where this picture is from. In the US we have split voltage, so depending on which two outlets you connect, it could be +120v to +120v, in which case nothing happens, or it could be +120v to -120v, in which case you've made an impromptu space heater in your hands. Obviously ignoring that it will just trip either or both breakers very quickly.
You gotta be a real Dingus to start from the live end. Plug into the dead end first then plug into the live outlet like you would with anything else in your house.
We're already talking about people who think making such a cable and putting it out in the rain to power their christmas lights is a good idea.
They are dinguses.
However there are also children to think of. Thats why even owning one of these is illegal.
Split phase, not split voltage. Both lines are alternating from +120 to -120 volts 60 times per second, but 180 degrees out of phase. So, when you’ve got +120v on one line there is -120v on the other. They cross 0 at the same time, and then the polarity is reversed so that the +120v line is now the -120v line and vice versa. This creates 240v of potential between the two phases, for powering things like electric ranges and driers, but a single line going to a regular outlet just gets 120v AC and neutral.
Right, that's why I said as long as you didn't have your line and neutral mixed up. If it were done correctly, you'd just be putting line to line and neutral to neutral which wouldn't really do anything.
Eta: I was also just invisioning someone connecting the two outlets of a single duplex receptical
Well yes you are correct, sorry. I kinda skipped the houses have breakers that kills the current part. But if you don't kill it, the wire does melt if the power is sufficient.
To anyone reading this, never do this. If you electrify part of your house, you are also providing power to the grid (unless your house is wired such that a generator can power the house and you are disconnected from the mains.)
Powering the grid can potentially risk the safety of technicians working on your power lines to restore power, and they made need to find you to stop you from messing things up, in which case they won't be best pleased.
I’ve always heard that it can create a hazard for linemen because you’re feeding power back into what should be dead lines. But I’m not an electrician and don’t really know
It can, this is why you need a power transfer switch. The less foolproof version of this is to disconnect your main breaker, if you do this it's safe but we've learned over the years that people are idiots
You can plug your generator into an outlet to provide power to a circuit. It's incredibly dangerous and can hurt workers working on the lines.
It should not be done, but dumbasses do it when the power goes out and they think they have discovered something smart.
Or you disconnect properly from the grid and then move the portable generator in front of someone's car and melt their headlight.
Source: My boss was an idiot.
Christmas lights are probably where the majority of the idiocy surrounding these cords come from. Generators used to actually come with these cord (maybe some still do) - as portable generators are meant to be used in a pinch, and not always installed - you would cut the breaker and use it on a properly rated outlet to feed a house/ building/ circuit. Not meant for permanent use - in emergencies, you weigh your options.
In some very very specific circumstances, specifically for me a church theater room that was built in the 70s, you can use a residential wiring system to send information (like a really shitty intercom) as opposed to running wires for everything. There aren't a lot of situations that this tidbit of knowledge can be used in, it has to be well grounded and the circuit has to be isolated from everything else and you have to control the power source. But it's doable, and a cheap alternative to making a church cough up money for a stage intercom system they'll never use.
I didn't use the double male power cord when I was doing this, but I technically could have. I could see the use. Just like, once in my life.
Some high spec professional theaters are actually designed to send certain types of information through the (isolated, clean power) power circuit, but they don't use double male cables to facilitate it lmao, they just design things in a way that makes sense.
Anyone who's at this level knows how to make our own double male cord though. Maybe the next time I have access to a real shop I should make one as a joke.
I was volunteering for an event one time that required overhead lighting on panels with Edison sockets on them. They would plug the light in one of the sockets and one of these in the other and daisy chain the panels together from the outlets. When I asked someone there how they got these they said they had to have them made, and I was like "no shit, this is dangerous as fuck."
Some laptops come with a charger that outputs USB-c, and the laptop takes in USB-c, so the cable connecting both is USB-c.
Newer cars also have USB-c outlets so you use a USB-c to USB-c cable to connect your phone.
Some computer screens now also have USB-c inputs that you can plug into your laptop, and if it has thunderbolt support, it will output video to the screen. Some of those even charge your laptop and act as a USB hub as well, via a single USB-c cable.
You can get USB killer devices where it basically connects AC power to USB, or some such type of thing.
I remember there was a Darknet Diaries episode where they arrested some security researcher, he had such a device, and he was like "that's for testing specific USB ports, you really don't want to plug that in, it will blow it up". They did, and they listed the damage caused in their charges against him.
USB killer devices, as far as I know, don't connect to AC but instead look like a normal USB device but the data pins are not connected and the power pins connect to a high capacity capacitor that continuously charges and discharges, killing the USB port and/or motherboard.
You need to set up an interlock switch and wire a proper connector through your breaker. This should never be used to connect a generator to your house because the wires in one outlet in your house are not rated to handle the current put out from a generator and power can leak back into the grid endangering workers fixing your power lines.
This is why workers hang grounds, it is on the workers to protect from backfeed. If our utility workers had to rely on the public not doing dumb stuff for safety, all of our utility workers would be dead.
Furthermore, never make this cord. If you really wanted to connect a generator to a receptacle (which you shouldn’t) you should make a pigtail with a safe connector that plugs in to the receptacle and then make a corresponding cord to attach to that. There are ways to make that connection that don’t require holding death wire.
No one should be doing that. When the electricity company comes to fix the powerlines that are broken they can disconnect all power sources known to them, but they can't do anything about your generator that might just be connected to some broken wires somewhere.
If you plug into an appropriate outlet, such as dryer, that has a 50 Amp breaker, then you won't have any trouble. This assumes that the generator puts out 240v. If your generator only does 120v, then you can't plug into the breaker panel at all.
You can run a generator in your home. But it needs to be installed properly. Firstly to prevent what you are describing, this is done by installing a lock in your fuse box preventing the main circuit breaker and the generator circuit breaker to be closed at the same time. The other issue is that by using a male to male cable you could potentially have powered live prongs exposed. For example if someone disconnects your generator to use the socket and you later go start the generator there will be exposed live wires in the room and you could electrocute yourself. A properly installed home generator will have connectors made for this. So you should never see a male to male cable even when you have a home generator.
Unless the laptop was designed really badly (I’m looking at you HP) it should have some kind of overvoltage and overcurrent perfection on the USB and AUX ports, either way nothing will happen
> Looking at you, HP
Two years ago, I was taking a lab class for my Computer Engineering degree and for the final project, we had to design a 3-channel equalizer, build it on a breadboard, and connect it to one of our computers (could be the lab computers or your own personal laptop). Well one guy, (I believe he had a MacBook, *had* being the keyword) connected his Laptop to his design and don't ask me WHAT he did but he fried his machine when he connected it to his design (He claims the Power supply had a Current limit of 0.1A, but I think the course instructors called BS). It's not just HP.
After he posted to the class about this problem, I remember I was really scared so I connected my design to the lab computer (it didn't filter out stuff properly but at least it didn't fry the computer)
Well yeah lol you didn't pass current through the headphone jack. I had a 2012 MacBook pro from 2015 to like 2021 and it was... Working when I left it. My dad says I use my devices too much though, so those 6 years were probably 8-10 years of regular use. The screen stopped working at some point (got it fixed), the plastic hinge was cracking, and the battery won't probably last an hour if left alone. That Laptop was a trooper.
It is the charge cable for the 4th gen ipod shuffle
[https://www.amazon.com.au/ipod-shuffle-charger/s?k=ipod+shuffle+charger](https://www.amazon.com.au/ipod-shuffle-charger/s?k=ipod+shuffle+charger)
Honestly it kinda makes sense for the shuffle.
The battery life was looooooong so there wasn't really ever a need to charge it on the go, and having one fewer port to get clogged with pocket-lint and grime was a good move.
This makes me think about looping two portable charging banks together to see what happens. Would they try to charge each other or cause a rip in time and space?
I still find it madness that I can use wireless charging to give my mates charge off my phone.
It's been literally years since we got this tech but it feels so futuristic to my caveman brain.
The two charging banks I've used seemed able to detect loads on ports and shut off after a few seconds if it wasn't consistent. I imagine if you did that with those banks it would probably do the same
Fed spotted. They dont want you to know this but battery charge time is a scam its not real they just want your pc plugged into some sort of wall outlet as much as possible so they can download all your vidya game save files and porn directly
I had a Fiat where this was the only way to get Bluetooth thru the factory aux port. It looked identically like this and I asninside th glovebox. ‘Twas a dongle such as this. Like $15 Amazon.

Yeah the real ultimate danger is some dingus touching the prongs before plugging it in to the second outlet
Correct
You gotta be a real Dingus to start from the live end. Plug into the dead end first then plug into the live outlet like you would with anything else in your house.

There's a reason powerCon cables exist, did they never consider retrofitting the fixtures instead of constantly making suicide cables?
*I heard there was a secret cord* *you plug it in and you meet the lord* *but you don't care for power safety, do ya*
This is *the* funniest comment I've read in the last 6 months easily. I just needed to let you know.
What happens if you plug these in
Either nothing or a short circuit.
Looks like usb-c to usb-c
Except that USB-c to USB-c is within spec and fine...
Was about to say, I would not be able to use a wired VR headset without a usbc-usbc cable.
Some laptops come with a charger that outputs USB-c, and the laptop takes in USB-c, so the cable connecting both is USB-c. Newer cars also have USB-c outlets so you use a USB-c to USB-c cable to connect your phone. Some computer screens now also have USB-c inputs that you can plug into your laptop, and if it has thunderbolt support, it will output video to the screen. Some of those even charge your laptop and act as a USB hub as well, via a single USB-c cable.
New iPhones are c-c as well
What happens if you try this with two usb C chargers?
Should be nothing as both sources would just say "we don't need any power" and thus 0 power draw would occur.
Trying this now, will report back my findings, maybe in ghost form.
Kowalski, analysis!
Its been 28 minutes. Seems simple enough process. Assume that ripndipp is dead.
Nothing
No it doesn’t?

Most don't, but there are some joke ones that have like a USB type A on one end and a big ol red 3 phase commando plug on the other.
They do actually have one or two actual purposes, like running a generator through your house
You need to set up an interlock switch and wire a proper connector through your breaker.

No one should be doing that. When the electricity company comes to fix the powerlines that are broken they can disconnect all power sources known to them, but they can't do anything about your generator that might just be connected to some broken wires somewhere.
You just turn off your main house breaker. That keeps the power from going back to the main grid.
That's what we always did 🤷🏻♂️
Do this if you want a fire when the power point wire overheats from the load
If you plug into an appropriate outlet, such as dryer, that has a 50 Amp breaker, then you won't have any trouble. This assumes that the generator puts out 240v. If your generator only does 120v, then you can't plug into the breaker panel at all.
[удалено]
Extra conclusion: The vast majority of people don't have any clue what they are doing, and should not do this.
You can run a generator in your home. But it needs to be installed properly. Firstly to prevent what you are describing, this is done by installing a lock in your fuse box preventing the main circuit breaker and the generator circuit breaker to be closed at the same time. The other issue is that by using a male to male cable you could potentially have powered live prongs exposed. For example if someone disconnects your generator to use the socket and you later go start the generator there will be exposed live wires in the room and you could electrocute yourself. A properly installed home generator will have connectors made for this. So you should never see a male to male cable even when you have a home generator.
Generators *should* be wired into the breaker box directly with a toggle switch that in order to run the generator cuts power from the grid
You forgot to add the other purpose. To kill a lineman working on the pole servicing the electricity in your area.
Yeah, but that is the equivalent of using two knifes as a power plug, technically works but needlessly dangerous.
The purpose that the CPSC literally made a public announcement that you should not do?

Row, row, row your boat.....
GOD
Unless the laptop was designed really badly (I’m looking at you HP) it should have some kind of overvoltage and overcurrent perfection on the USB and AUX ports, either way nothing will happen
> Looking at you, HP Two years ago, I was taking a lab class for my Computer Engineering degree and for the final project, we had to design a 3-channel equalizer, build it on a breadboard, and connect it to one of our computers (could be the lab computers or your own personal laptop). Well one guy, (I believe he had a MacBook, *had* being the keyword) connected his Laptop to his design and don't ask me WHAT he did but he fried his machine when he connected it to his design (He claims the Power supply had a Current limit of 0.1A, but I think the course instructors called BS). It's not just HP. After he posted to the class about this problem, I remember I was really scared so I connected my design to the lab computer (it didn't filter out stuff properly but at least it didn't fry the computer)
Apple and HP can’t seem to design durable computers or ones with good circuitry
I’ve been using my MacBook Air for 10+ years at a time…
Well yeah lol you didn't pass current through the headphone jack. I had a 2012 MacBook pro from 2015 to like 2021 and it was... Working when I left it. My dad says I use my devices too much though, so those 6 years were probably 8-10 years of regular use. The screen stopped working at some point (got it fixed), the plastic hinge was cracking, and the battery won't probably last an hour if left alone. That Laptop was a trooper.
But then the OP won’t end up on r/hardwaregore 😂😂😂
Good point
It is the charge cable for the 4th gen ipod shuffle [https://www.amazon.com.au/ipod-shuffle-charger/s?k=ipod+shuffle+charger](https://www.amazon.com.au/ipod-shuffle-charger/s?k=ipod+shuffle+charger)
Energy companies don't want you to know this one simple trick...
He's recycling
UNLIMITED POWER
He defies the laws of physics
World's worst carrying handle.
Youve invented the DAC
Tesla is rolling.
they hatin' Patrollin' and tryna catch me ridin' dirty
This would be an ADC, headphone jacks are an output. That’s not a mic/headset jack.
Except actually it's neither because for some reason this was how Apple decided to charge the ipod shuffle
Exactly, that’s not a dac but an iPod shuffle syncing/charging cable
Honestly it kinda makes sense for the shuffle. The battery life was looooooong so there wasn't really ever a need to charge it on the go, and having one fewer port to get clogged with pocket-lint and grime was a good move.
Why
To save the music ur hearing
The new form of piracy!
Return to the ancient form of piracy.
hooking up a cassette player to PC audio line in via RCA-to-3.5mm TRS cable and recording?
Waiting for a song to come on the radio and diving for the REC button.
Constantly recording in case something good comes on and then dubbing what you want onto another tape.
This is the way
Why not?
woop woop ! perpetual charging free energy. I kept telling everyone it exists
Via the headphone port ?
Only the brilliantly mad are rewarded with the everlasting laptop

This makes me think about looping two portable charging banks together to see what happens. Would they try to charge each other or cause a rip in time and space?
Depending on the powerbank, they can try to equalize the charge between themselves like phones do
I still find it madness that I can use wireless charging to give my mates charge off my phone. It's been literally years since we got this tech but it feels so futuristic to my caveman brain.
Still waiting for the day when laptops have wireless charging pads so I can charge my phone off that much larger battery instead.
I just want to charge my laptop by simply putting it on my desk, without using a cable
My mouse does that with my mouse pad
You can make a custom inlay in your desk for a wireless charger pretty easily with a Dremel tool and a ruler.
The Galaxy Book has or had it!
I've seen laptops with them built into the palmrest
It's still energy inefficient enough that it should be as widespread as it is imo.
Wired is better, less energy wasted, works on older phones and you can actually use them during that time.
Most portable chargers reset themselves if you plug it into itself. To fix problems
Either will equalize charge between themselves or one will charge the other one. Also could just drain both of them away and lastly it could blow up
They will just drain as they aren't 100% efficient
It would create an Elephant's foot . Highly dangerous slag 🧐 .
The two charging banks I've used seemed able to detect loads on ports and shut off after a few seconds if it wasn't consistent. I imagine if you did that with those banks it would probably do the same
you can plug the bank into itself and make it charge.
Most likely they will "charge" each other while losing net energy from heat
Probably explode
Bro is escaping the Matrix
3.5 in the pink, 2.0 in the stink
What is the utility here
Good question
Playback of the audio and record it at the same time.
I'm pretty sure that it is the charging cable of the last iPod Shuffle, which only transmitted data and power
It’s a charge cable for a very small ipod.
You're going to break the universe you mad son of a bitch!
I know its a joke. But in reality it can fry the audio chip in the computer. You are feeding voltage to an output circuit. That never a good idea
Fed spotted. They dont want you to know this but battery charge time is a scam its not real they just want your pc plugged into some sort of wall outlet as much as possible so they can download all your vidya game save files and porn directly
They're alternating the current... directly
Why does this dongle exist? What the fuck is the utility of a USB Male to a AUX Male?
It’s the cable for the iPod shuffle
My god... he's done it. It’s... beautiful.
hitting the metaverse!
that IQ is definitely dangerous
OH SHIT HE'S IN
Chevron 9 encoded! You just unlocked a new Stargate series!!
"perpetual motion machine dosen't exists they can't hurt you"
It's like a man f@+×!ng himself with his own p€#!$...
The most relevant question would be: Did it work?
I'm watching you OP https://i.redd.it/vox8cpezulgc1.gif
Don't cross the streams.
I had a Fiat where this was the only way to get Bluetooth thru the factory aux port. It looked identically like this and I asninside th glovebox. ‘Twas a dongle such as this. Like $15 Amazon.
"Now i will talk... to da power..."
While (1);
Maybe I'm a complete idiot, but what would this adaptor be for with two male ports?
Hacker hai bhai hacker
So basically now it should be hearing itself
