Dear, When I try to charge my Tesla at home on a schuko ; I get on 4 red blinks (grounding issue). Except for one socket, the difference is that it's using the exact same ground, with one difference : there is a breaker right before this (extra breaker) as it's on my workbench. Funny that when I use the source of my workbench it says bad ground, when I connect my workbench to the same source (with breaker added) it works. Any idea what this is? Does it really expect N+earth to be connected? as this is not required by our distribution.
