      What does it matter if he grabs a single pair of pliers with both hands? Why did he make that bend in the middle tho?

        Electricity likes the path of least resistance to ground. If you are only touching with one hand, most likely the current well run down that side of your body to ground more or less. If both hands are touching it makes it more likely for the current to cross your heart which greatly increases the risk of death

          This is why in electrical trade you’re taught to use your right hand, with your right foot below your shoulder, and left leg out (when doing anything sketchy).

          If you do get shocked then the current will travel down the right-side of your body, and out through your right leg.

          That’s not to say throw caution to the wind, but some people need to do risky things (that’s why sparkies get paid a lot).

          For example, a guy I used to work with had to repair a switchboard at the hospital, which supplied power to the theatre rooms. Time sensitive matter as I’m sure you can imagine.

          This guy was a pro, and was wise to take the safety precaution. When it came time to power back on the switchboard, not only did he right-hand/right-foot, he shielded his body and face with the switchboards door panel.

          Something inside blew up, and he got his hand burned quite badly. Fortunate for him to be at a hospital. In this case he didn’t need the right-hand/right-foot technique, but if things happened differently, it could have saved his life.

            I can’t think of any reason the ability to watch movies would ever be that important, hospital or otherwise.

              You are probably being sarcastic, but for those who haven’t come across it - operating rooms are often called theaters.

            It obviously isn’t. You can see it sparking in the video as it energized the wire. If it was to ground those minor sparks would have been massive arcing and that wire would melt.

          But if it didn’t shock him while he was using one hand it’s not gonna shock him when he switched to using both hands either.

            You’re not wrong lmfao. But it’s exactly like “I don’t need a helmet, I simply won’t get hit”.

            Im not convinced with this much juice it would have made a difference, and if you’re committed to doing it this way you ARE probably better off doing whatever helps you avoid the worst, not mitigating it, BUT there are a LOT of stories of people who have been saved by best practices.

        The bend at the end, I suppose is to put the strip in tension and make it less likely it will slip

        Grabbing with both hands you make it extremely easy for electricity to go through your heart. Electricians are usually thought not to use both hands for anything if possible, since if cable is powered chances of serious injury are slimmer. Also twist at the end was to increase tension on the wire.

        i imagine that puts the wire under tension for better contact at both ends. pretty smart actually.

      I think it’s more of a case “fuck around, find out” but without any rules set in place they can incrementally fuck around and find out. That is to say, people tried this, some of them didn’t die, they got better at it, fewer people died, etc. Eventually you get good at managing risks. Not that they are smart risks. To a degree this makes people think and be extra careful, instead of just relying on rules to ensure their safety. Not that am implying electricians in other countries don’t think just that when rules are set in place there’s not so much of a tension and remembering whether you pissed on your slippers before working with electricity.

    I was in rural India for a friend’s wedding. They set up a giant tent pavilion to use as a dining hall, with fans hanging from the top. This was a ways away from the main house, but there were some power lines nearby so they just got power straight from the grid.

    Also, day of the wedding, there was a large sound system for the musicians and priest. All the components were plugged into a power strip, which was powered by a couple loose wires stuffed into an outlet

    fun fact: there’s 400 Volts between the terminals laterally. that’s gonna be one hell of a cardiac arrest.

        Actually it’s both. You can have as high of a current as you want, if there’s no high enough voltage potential, current simply won’t flow. Any battery can push more than few amps of current easily, but voltage potential is not high enough to push it through your body. In general you are right, minimal amounts of current are enough to cramp a muscle, however it takes a lot of pushing to get to that muscle.

        you need at least 100V DC or 50V AC to break the skin’s resistance, then there has to be at least 30 mA. which isn’t hard to do with a body resistance of a couple kΩ.

    OK so yeah, that guy doing it if crazy. That has been covered. But that also looks to be at ground level where anyone can walk by and touch it?!?! That seems like a bad idea too

    I’ve legit seen an electrician do similar in a 480V switchgear in the US… used to help with installs of industrial submetering equipment, but rather than waiting for a facility shutdown, we would often install our CTs on live equipment. IIRC he wasn’t even wearing arc flash gear…
