      We call them a Deadman’s cable up here, and sadly they’re still quite frequently used in the northern rural areas because it costs almost $2,000 to have a dedicated bypass switch installed(generator hookup) so nobody does it, they just throw the Main and hope they don’t put too much stress on the internal lines.

      Is it legal? Hell no but they do it anyway

        I did this.
        Is it stupid? Yes. Did it work? Also yes. For the amount of time that we’d have power out, it was just way to easy to throw a breaker and connect it like this just to keep a small heater and a light running. If I had the money at the time I would have loved battery backup/ bypass but this cost $2 and an old cord.

          Especially considering that having a functional stove nowadays skyrockets your insurance. A lot of people used to use wood stoves as the backup heat source if the power went out, we still have one ourselves however it’s “non-functional” , it probably is to be honest it hasn’t been ran for a few years now but it was going to Skyrocket the insurance if we had it listed as a functional Appliance

          There are way cheaper ways to have a safe interconnect then those second box systems. There are kits that install a plate next to the main breaker and prevent both the main breaker and the next closest breaker from both being on at the same time. You then setup the second breaker to be your generator inlet. Here’s a DIY version, but there are kits for all major brands.

    I heard there was a secret cord.
    you plug it in to meet the lord.
    But you don’t really care for safety, do ya?
    It goes like this, you plug it in,
    And in a flash, the lights go dim,
    The power’s gone,
    and now it’s running through ya.

        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 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. They’d need to skip both ground out and test to be electrocuted by an asshole with a generator.

        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?

            Well, if you put them right in the normal outlet you bypass breaker and built in fuses, if breaker is open. If it is closed, then it maybe should pop if whole net outside house consumes more current than your house is allowed to (so maybe immediately), but still provides no protection inside. Or maybe if you have individual low-current rated breakers for every outlet, then yes, in this specific scenario it should technically work. Still, you know, generally bad idea.

        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

        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.

      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.

      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!”

    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.

            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

      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.

          Yeah for sure, they do make generator sockets, which are a fully shrouded male plug meant to be used with a generator transfer switch.

          But still, people do hook up generators this way sometimes. Regardless def not many good uses for a suicide cable
