So what's the best way to safely wire the house, and make sure the RCDs are still working?
Do we connect the ground of the car to the earth of the house or not?
I understand we can't bond the neutral of the car with the ground of the car, otherwise the RCD of the car trips.
Can we bond the neutral of the car with the ground of the house, and ignore the ground of the car?
What happens if instead we don't connect the ground of the car with the ground of the house, and we don't bond the neutral with the ground? Basically the equipment in the house would still be grounded to earth, but there would be no return path to the neutral of the car: I guess the RCDs inside the house wouldn't work, but maybe the one inside the car would still defect a fault?
