Is it possible to take zero from the ground? there is a suspicion that they are stealing electricity, have you met this? maybe someone and practicing electricians met this

Answer 1

You can, but it's dangerous. And yet - the meter will still count electricity.
About 10 years ago I was interested in this issue. I read the forums - there 50% say that they will count, 50 - that they will not. Then on Youtube I looked at a couple of detailed answers from an example. There were examples, they heated water with a boiler. But this is very dangerous.

Answer 2

This usually ends up in differential protection, especially in modern electrical installations.

Answer 3

Theoretically, theft "with your own land" is possible, BUT for this it is necessary that:

1. the counter was classic / 1 but elemental ( 1 current sensor)
   
2. connected incorrectly (phase changes with zero, i.e. electrician + controller "interested" or inattentive)
   

Answer 4

in principle, the potential of "zero" should be equal to "ground".
the consumed electricity is calculated by the passed current in the phase wire.
in a three-phase system, the powers passed through each phase wire are summed up.
stealing electricity while playing by switching the earth will not work.
