Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
This guy is interesting. Turns out he’s self taught - he’s not an electrician or an engineer. He’s a plumber.
I am 90 seconds into this and I hope it's a 12 episode per season thing.
It's cool and all but what THE FUCK is up with his lugs? I'm not sure I can keep watching as he casually gestures around what looks like melted insulation. Maybe it's some kind of grease or no-ox I don't know about
TL/DR: ground wire is an emergency current path back to the panel aka "backup neutral". Under normal circumstances it does not carry any current, but is there to help trip your breakers (and in some cases GFCIs) should hot wire ever fail to the ground wire or to a metal body of your appliance. Unlike other wires it does not need to be insulated. It connects to the neutral and to the grounding rod at your panel.
I think the video is not bad, but boy I quit at 7 minutes our of 20
