A number of countries have "lost neutral" detection incorporated as part of the suppliers equipment.
Back in the day, when Mandela was still locked up, the ANC used to see theft of electricity(fiddling the meter) and theft of the infrastructure assets (ie nicking copper) as "legitimate political protest"
As the neutral is usually the lowest conductor on an aerial flight and isn't usually "hot" that would be the prime target for weighing in.
If you stick something like a 1KOhm resistor in with a rod, and put a DP RCD as part of the cut out, before the PME link, if the neutral goes AWOL, then the whole installation trips Try a Goole for ESKOM lost Neutral Detector
All totally unnecessary of course - just make the bloody cars and charger double insulated.
