      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.

    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…
