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?
We intentionally made suicide cords all the time at my old job lol
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.
Practical IQ test with binary result (“pass”/“fail”).
My dumbass made one by accident. Plugged it in, walked to the other end, picked it up my saw, “Shit. How did I throw the wrong end out here?” Whatever, we’ve all strung the extension cord backwards before. Here come the IQ test.
Walked to the other end of the cord, yanked it and threw that end back out into yard, plugged it in. Went back to my saw, “Oh for fuck’s sake!”
bruh moment
But you dont really care about voltage, do ya?
It goes like this, on the the 25th, a minor shock? No, a mortal shift…
The baffled men are meeting now their maker.
Hallelujah, Hallelujah,
Hallelujah, Hallelujah!
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
Just use 2 paper clips and some duct tape, problem solved!

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.
I don’t know much about circuits but could you switch the polarity to make this work?
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.
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.
I know even less probably but I’m going to say yes and let you find out for me.
I don’t really get it. Sure, the exposed prongs would be energized once you plugged one side in, but if you plugged the other side into a second outlet (assuming you didn’t cross live/neutral), nothing would happen. (those two outlets were likely tied together anyway)
Two things: 1: there’s a high chance you do cross live and neutral, or even live and live on different phases. 2: using it to plug in a generator to power your house can kill electrical workers who are trying to restore a power outage. (If you fail to open your circuit breaker.)
50-50 chance whether those two outlets are on the same phase or opposite faces; if it’s the latter, congrats, that’s a 240V short.
Besides, if there’s an outlet at the far end of your strong of lights, you don’t need this, you just plug it in there
You don’t work around dangerous things assuming you’ll never make a mistake, you work around dangerous things assuming you’ll never make three mistakes at the same time.
You are not immune to making one (or more) mistakes, no matter how careful you think you are.
Correction: you don’t work around dangerous things assuming you’ll make a mistake long
In addition to the exposed prongs, it also means you are passing current into a circuit of unknown capacity without using a safety breaker. You may also be back feeding into your neighborhood power grid and can kill people in the street/other houses that were not expecting the lines to be energized.
Double live is very bad and the cord becomes a literal short. If you’re lucky a breaker will flip or fuse burn out. If you’re not so lucky you have a cable thats either going to start a fire burning its insulation off and melting itself, or potentially exploding depending on quality and type of cable.
The problem really is the super exposed hot prong you now have once you plug one end in
Well, maybe it’s because you may die if you accidentally touched touched the prongs? The purpose of female plugs is among other reasons to prevent accidentally touching them.
I guess the fact that it can kill you easily is not enough to call it a suicide cable lmao
Yeah, let’s call it a self defence cable instead. Like a corded taser.
I’m not American, Christmas lights aren’t a thing here like they’re in the US, can someone explain?
Strand of exterior lights, one end male plug one female. Idiots start to mount the lights with the female end near their outlet. Get done, become confused, go to store for male to male cord to plug into female end.
The female end is for chaining multiple strands, not for supplying power (directly) from the power socket.
The power can go through the female end just fine, that’s not the problem. The problem is people plug this “suicide cable” into the wall first, thus creating a 120v taser of sorts. Like someone else in this thread said, the only problem from cables like that is people tend to try to backfeed energy into the system with a generator or solar panels. Boom.
So is the problem solved by not plugging it into a powered wall plug? Just like… flick the switch off, like you would a light switch before changing a bulb?
Yes, but if someone trips over the cord there is a 50% chance the wrong side comes unplugged and potentially kills them, hence why they don’t make these cords
Most American outlets aren’t switched. They can be but most aren’t. If you’re really paranoid you can throw the breaker at the panel.
Wait really? I don’t think I have a single unswitched plug in my house, and I’ve never seen another house with even a single unswitched plug. Do US people need to unplug cords to get rid of standby lights?
Behold the typical North American duplex power outlet. They typically do not have a built in switch. They might be controlled by a light switch, so you can throw a switch near the door and have the floor lamps turn on but most are always hot.
That’s Australia’s.
Because of the no switch, does US plugs spark a lot when getting plugged in?
The solution is pulling down your Christmas lights and hanging them back up the right way.
Also, at the end of the chain there is a male terminal exposed with live current. Could cause a fire I guess.
Isnt having an open end really dangerous?
Every Christmas light string I have seen has had a small fuse inside of the plug, so even if you managed to get a female plug full of water or something and somehow manage to get shocked before a breaker trips in the outlet, you’re probably just going to blow the fuse.
Every Christmas light I’ve ever seen were all low voltage. The last Christmas light that was directly into main power instead of having a power convertor plug was decades ago. I guess that’s EU regulations at work.
You cam cover them with electric tape or put a cover on them. It’s nobmore dangerous than your home’s exterior outlets though.
Homes exterior outlets??? It might be europe but we dont have neither of those seemingly pretty dangerous things.
I’m going to assume you are English, since they seem to have extreme fear of electric shocks. But there is never any issue with exterior outlets. 99% of them have covers like this and are no nore dangerous that light switches on a patio or in your bathroom.
The places where i lived for longer times are hungary, sweden and ireland. Ireland has the same plug as the uk, and in hungary and sweden its the general eu plug. While the plug you linked does seem mostly safe, i think its a good thing that the uk takes electrical safety seriously. My main problem with the female plug is its a christmas tree that can catch on fire and i dont think an exposed wire near it is a good idea. If the cover is required in some way to complete the circuit then i have no problem with it. Thats good design but the sad thing is most of times they skip the good design part.
Thr cover doesn’t complete the circuit, it just prevents debris getting into the socket. An extension cord doesn’t have a cover on the female end and it is completely safe, just like an outlet in a bathroom or a surge protector.
Gfci outlets are pretty cool technology. They make getting electrocuted impossible as long they are installed correctly.
…in europe. From what i heard america doesnt really have them.
Considering they are required by code to have them anywhere there is water. America does have them.
Aaah, gotcha! Thank you!
A strand of christmas lights resembles an extension cord, but they tend to be made of smaller gauge wire and obviously have little sockets for tiny light bulbs spaced along them. They typically have 2-prong male plug on one end, often with a 2-prong female pass through on the back so you could plug more than one strand into the same receptacle, and they usually end in a female plug so they can be daisy chained.
Sometimes, when installing them on a house or something, the person installing them may not pay attention to which direction is which, and end up installing them so that the female-only end is near where they intended to plug them in. So instead of pulling them down, or running a long extension cord, they go to the hardware store looking for a male-to-male plug adapter.
Power plugs and sockets are gendered for a very good reason; the female receptacle keeps the energized contacts protected inside, and the male plug’s contacts should only be energized when plugged in and their outer shells protect them. A male-to-male cable when one end is plugged in and the other is free now has exposed mains current just waving around in the open air ready to kill someone. And, on a smaller note with christmas lights, they usually have a fuse built into the plug, and plugging them in backwards bypasses this for at least the first strand, so it’s technically 102.7% unsafe to do this.
The other thing a male-to-male adapter or cable is sometimes used for is to attach a portable generator to your home’s electrical system by just plugging it into an outlet, especially during a power failure. They do make what are essentially special male receptacles I think mainly for the RV industry for attaching generators like that, most houses won’t have these. Plugging it into a normal wall socket will actually work, but 1. you have bypassed the breaker panel, so the breakers no longer provide over-current protection. You could overheat the wires in the walls and burn down the house. 2. there’s a possibility that you’re feeding electricity to the entire house through the breaker box and even out to the transformer, which means the lines could be energized for linemen working on them. Throwing the main breaker might prevent that? They make switching gear designed for buildings with their own backup generators that can either manually or automatically sever their connection to the grid when on internal power, but again a doofus trying to make one of these cables probably doesn’t have one of those.
Outstanding, thank you for this
Wow. I had no idea. Thank you for educating me.
Their lights usually have a plug on one end and a socket on the other. Ppl put them around the exterior of their hoses, then realise they did it the wrong way, and the socket end is near the outlet they wanted to plug them in.
Or they mounted two strands of lights, and where they meet up it’s either 2 plugs or two sockets accidentally.
So if these are people wiring their Christmas lights wrong, assuming these are led lights, doesn’t this “solution” not work bc of the polarity anyway? Or is that only a DC thing with diodes? I only did okay in my physics electricity stuff lol
It would still work. But it is VERY dangerous. 1. The far end of the light string will now have exposed metal prongs that are energized at 120v, which can be fatal. 2. If the other end gets plugged into a socket, there is a 50% chance it will be a different circuit on a different phase, which can create a 240v direct short, across a wire that has no properly sized circuit breaker. 3. Using it to plug a generator into your house during a power outage can kill electrical workers trying to fix the outage if you fail to open your circuit breakers.
I knew that much, I was more interested in how diodes work on AC lol
In AC, diodes work half the time, every 1/60 second. The “good” LEDs will have circuitry to fully rectify the AC into DC, drop the voltage properly, and smooth the peaks and valleys, so they will be continuously lit. So the cheap LED Christmas lights might have a slight flicker, and the good ones are steady. (Or get fancy with chasing colors, etc.)
All of that happens inside each of the “bulb” enclosures, or sometimes in a box at one end, so it technically doesn’t matter which end they are getting electricity from, since the socket at the far end is still just connected in parallel to the plug at the near end. (Otherwise you wouldn’t be able to link them together.)
It’s just a really bad dangerous idea to reverse them.
Let me introduce you to the FULL BRIDGE RECTIFIER!
No, alternating current doesn’t have a polarity like DC does.
For simple stuff such as those lights, polarity is usually not a problem when using AC.
In case of AC (Alternating Current), instead of having a + and - pole, you have a Line and a Neutral terminal.
The Line terminal goes + … - … + … - … + … - with time and the Neutral stays at 0.
When connecting to LEDs and such, you have an AC to DC converter, which tends to be fine no matter which pin you put in which hole.
In household wiring polarity does matter, especially if you are assembling plugs. Only one of the three wires is carrying live current (hot), the other two are the neutral return path, and ground which is for safety. If you accidentally switch polarity, you can cross hot to neutral and cause a short circuit.
My bad. I wasn’t clear enough.
I was talking about 2 pin plugs, as shown in the post and how it is usually for those cheap lighting thingies.
Switching the neutral and hot pins doesn’t matter except for appliances with exposed metal tied to the neutral pin, which is pretty much exclusive Edison screw lamps. This is why many plugs (especially those that immediately go to a rectifier) don’t bother with polarization.
Swtching hot and ground is a problem
Ah, so that’s why it’s half power compared to DC, makes sense.
Kinda, it’s half the power because the power goes like the temporal average of the current squared, the current oscillates like sine or cosine, and the temporal average of a sine or cosine squared is 1/2.
Unless the AC is a square wave, in which case stuff becomes different.
-
Not really.
-
Where on earth would Mains be a square wave?
Low quality UPS Inverter
That’s not what Mains means.
As far as the appliance cares, it is the only input power it gets at that time.
-
I’ve used a suicide cord before in some rare instances. When I was finished I immediately took it apart.
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
You didn’t do it right…
You gotta lick it after you plug it in so you know it’s working.
Teehee, it tingles!
You can also use them to test the voltage, similar to testing a 9v battery.
aaaaaahhhhhhhhhhh lic-
