440v x 455 amps = 200kw.
DEFINITELY not safe in the rain lol
In fact, pros use insulated poles to handle that load. If you short it you’re likely vaporized.
NOT PRACTICAL.
How much energy is in a tank of gas? Why are there signs around the pumps warning people not to smoke?
But working around equipment capable of 400x400 plus??? Sheesh. I'm always very cautious when I have to open the breaker panel to replace or add a breaker or circuit... If I spill fuel at the station - well, I've never and I used to work at a gas station as a kid, but I've seen serious fuel spills - if there's a spill, you have a chance to get away before there's an ignition. If that 200 kW gets away from you, there's probably no warning, no grace period, you're toast, literally.
While I haven't had a serious fuel or electrical accident, I have seen others. If they had been working with a supercharger station instead of unleaded...I'd have probably seen a half dozen deaths or so over the years...
