cries in ground fault circuit interruptor
… but you don’t really care for logic do ya?
On the one hand, there are legitimate uses for double ended male cords. On the other, absolutely none of those legit uses invovle christmas lights
Okay but can we agree very very few uses besides generator hookup
generator hookup shouldn’t be one of those, as shouldn’t proper generator transfer switches have plugs designed so you don’t need a suicide cable?
i guess if someone’s putting up their lights backwards, then it makes sense that that person also thinks it’s less work to drive to the hardware store and buy a non-existent extension cord than it is to just redo the lights
They tried calling it a doom cord, but heavy metal band started having electrical problems.

Modern inverters do this somewhat safely by sensing the phase before outputting power.
Of course, you can’t tell just by looking, so I still would steer clear of the whole thing on principle.
How do you non-sketchily feed a generator’s power into your home?
You get a qualified tradesperson to wire it properly into your electrical distribution.
Lol this dude never turned hydro into diesel! Look at this guy!
The proper way of doing it is using what’s called a generator bypass switch, basically it’s a physical switch that runs before your fuse box, and it makes it impossible to have both the main and the generator being fed at the same time, so you can either have the main on or you could have the generator on. This prevents the electricity from your generator back feeding into the line and killing a line worker trying to restore power.
Sadly, like the other comments have said people tend to use these male to male cables in order to not have to pay the $2,000 to install the switch and instead choose to just turn the main breaker off and plug that cable in. But since it’s possible to have both the main and the generator on it’s not legal because if you forgot to throw the Main or if you did it incorrectly you could be putting workers at risk
Even disregarding the safety risk of using such a cable, not having a dedicated switch installed also means that you’re plugging your generator into usually an outside socket of the house, and those power lines aren’t usually meant to have a high load so you risk creating a fire from over straining the line as well
“risk a fire from staying the line with a high load”, wouldn’t the fuse in the line you plug it into simply open if you over load it?
The real way is a generator inlet, which is a male plug that’s interlocked with the main. So the cord ends up being a normal male/female cord
There are electrical panel accessories that automatically isolate the house
For the actual physical connection, you use a male receptacle
In order to do it legally, you also need the transfer switch, as has been mentioned.
Nice that the screws are included
If not, you can borrow them from your aunt
And also illegally expand your 1mx1m apartment with galvanized square steel and eco-friendly wood veneer while you’re at it
Technical details and the social contract mandate that your generator is never connected to the main power grid. The generator should be wired to an enclosed AC transfer switch. This switch will connect either the generator or the main grid to your home, but never both.
Some detail: If the generator is wired to the main grid it can prevent restoration of main grid power. While an AC transfer switch will perform the task, many jurisdictions mandate additional safety precautions (which can be quite expensive).
It can also kill a lineman working on the power lines outside your house, thinking they’re not energized.
It could. But, there’s more layers to this swiss cheese model of safety. For example, the lineman’s procedure is to ground out, then isolate, then test and to ground out. They’d need to skip both ground out and test to be electrocuted by an asshole with a generator.
What if the generator was connected after the lineman’s test?
Then ground out bypasses the body.
Of course, but we should never be advocating for the elimination of Swiss cheese slices. Don’t use the suicide plug, get it wired up correctly with isolation.
No problem.
I got these baddies
Memories. Me and my friends used to zap eachother with these before social media made everyone into cowards
It didn’t take the internet for people to be fearful and cautious around high voltage…
All I got to zap was myself.
Ok boomer
I’m guessing your turn was last and that’s why you’re still here.
Nah but we did stop when we took out the neighbourhood’s power with our fooling. Just as well since I’ve since heard it’s quite dangerous
Looks pretty weak sauce. I use jumper cables.
as someone who has strung a ton of lights the wrong way around on more than one occasion… I can understand the desire for some magic solution that doesnt require undoing and redoing your work…
but fuck, You don’t mess around with electricity.
People also make these stupid suicide cables to plug generators into houses during disasters, often backfeeding power into the lines that may be down and can cause serious injury to workers trying to restore power.
FYI, you can just turn off the main breaker of the residence to prevent backfeeding into the power lines.
If someone can’t make the own cord, what’s the chance they know how vital it is to flip the breaker?
… Except the breaker only interrupts the connection on the “hot” line…
You can, but if forgetting to flip a switch can result in death, then you need a stronger safety control
Someone incompetent enough to forget to shut off the main shouldn’t be operating a generator anyway.
That’s not the point. Normal, sensible people make mistakes because they are tired or stressed or got distracted or just plain unlucky, so things have to be designed so that people can make a mistake and it not instantly create a potentially lethal situation
I don’t think you completely understand what’s being discussed here.
Someone who’s not competent enough to install a proper transfer switch (or at least hire a professional to do it) shouldn’t be operating a generator.
Yeah, there is a reason why proper installations require actual transfer switches or at least a manual interlock to prevent both feeds being connected at the same time. I’m also not sure what would happen if your generator was out of phase with the grid when it reenergised, but I’m sure it wouldn’t be good
If your generator was connected to mains when they came back on it would probably just kill your generator. It is the least robust device in the chain. The next step is blowing up the transformer on the pole which is a spectacular light show. It is also very expensive, and will piss off your entire neighborhood who were just about to get power back and now have to wait for the power company to fix the transformer you blew up by being a dumb ass. Finally it is possible that you would trip out the switch yard which is going to make even more people angry. The biggest risk is you putting power back on the lines that people are working on. That transformer on the pole works both directions. It drops the usual 13.8kV on your local power lines to the 240/120V in your house. It will also turn the 120/240 from your generator into 13.8 on the lines that are being worked on. 13.8 will kill you before you even know you touched it. That is why line workers go through multiple tests before they get near lines they are working on. They will notice there is power on lines that are supposed to be dead. They will find where that power is coming from. They will fine you lots of money. There may be criminal charges.

Plugging the cord in the same outlet isn’t dangerous itself, but the prongs will be live on the end that’s not plugged in, I’d suggest not touching them. Where it IS dangerous is when people try to use them with a generator to back feed their panel. Don’t do that.
/But hardware stores don’t want to sell it tooooo youuu…/
/…tooo ya…/
I’ve used a suicide cord before in some rare instances. When I was finished I immediately took it apart.
You didn’t do it right…
I used to use one to get power into my popup camper…
Where was the power originally suppose to come in? They make power “Inlets” for that sort of thing. This one is designed with an Interconnect Switch for hooking into a system with Mains, but a camper with outlets should just have a inlet somewhere.
Fuck if I know… I bought the thing used from a buddy like 12 years ago and that was the cord he’d always used … Plugs into a regular outlet on the outside of the camper and then the outlets inside have power.
/me shrugs
If I ever buy one of these, I’d only ever use it to encase in resin and put on a shelf as a comedic ornament.
Fine, I’ll just use a couple of those with an ethernet coupler.
I don’t know much about circuits but could you switch the polarity to make this work?
I know even less probably but I’m going to say yes and let you find out for me.
Reversing polarity is a Starfleet-approved procedure in all situations.
It’s not that it won’t work - polarity doesn’t quite work like that in AC systems - it’s that as soon as you plug in one end, the other end has a pair of exposed metal contacts with mains voltage between them. One mistake, touching the contacts or having them come into something metal (like the ladder you are using to hang the Christmas lights) and someone dies
Also, once you plug it in to your strand of lights, the other end of your lights will have a live male plug dangling off it.
in AC, which is what home electricity uses, the polarity is constantly switching, from + , then - , then + , and so on, 50 or 60 times a second depending on where you live. This means that, unlike batteries, it’s symmetrical, and you can just splice the cables and attach two male plugs together and they will work regardless, even if you somehow attach the neutral to live and live to neutral, in fact in many countries you can actually buy just the plug without the cable and then you can assemble it yourself in whatever way you please.
of course tho, this should be done only if you have a decent understanding of electricity, and it should not be attempted by someone who lacks those competences, hence why hardware stores “gatekeep” male to male plugs. If you really need one and are sure you understand how they work, you can probably make one yourself.
Ah I see. You can tell I don’t know much about this lol. I figured it was like DC.
(If you) are sure you understand how they work
And
If you really need one
I understand how power systems work. But, I can’t come up with a situation where I’d use a male-male AC cord rather than a safer and more reliable alternative. Most relevant is simply cutting off the female termination and reterminating through a breaker to the outlet ($15 and 15 min).
Picture this: It’s 8pm in early December. You’ve been hanging lights on your house since about 10 this morning, and it’s long after dark. As you’re laying the last section, you realize that you’ve got two female connectors next to each other. Do you tear it up and do it again, or do you hack a solution together so you can go inside and thaw?
The suburban solution is to create a false dichotomy to rationalize outsourcing a simple electrical issue to Lowes.
The hack solution is to cut two ends and reterminate them.
I’d hack it. To do it well it’s 8 crimps, wire loom, and harness tape. So, 10 minutes and $5.
and you’d be right. If you are sure about it, and you know how it works, just make it yourself, so that you don’t need to put anyone else in danger of getting sued.
The reason hardware stores don’t sell them is that people WILL use them in a dangerous way, and they don’t want to be held responsible.
Makes sense. I’d not sell a hack job. But, for a temporary thing that’s mine, sure.
Tell me you’ve never used a generator without saying you’ve never used a generator.
Tell me you’ve never heard of an Interconnect and put the lives of every power line worker in your area at risk every time there’s a blackout without telling me…
Tell me you’ve never heard of turning off the main breaker before switching to generator power without saying it.
Interconnects remove an element of human error and putting Lineman at risk
Are you actually insane? Never EVER backfeed a socket like that. Way more dangerous than the Christmas light loonies.
Even with a generator, suicide cord is the WRONG way to do it.
Not like that’ll stop anyone anyways.
