I know someone who used to be a genius and apparently it was uncommon but not unheard of for someone to puncture a battery resulting in a violent fire that had to be put out by dumping a fuckload of sand onto it.
So this isn’t that far off from working at a Genius Bar normally.
Shouldn’t everything be grounded through the panel as well? I know I have a ground wire running out to a copper plate in the ground next to my house and my understanding was that if the neutral goes that would serve as the path to ground. Is this house missing that feature or am I wrong?
