Why not go for a TT system then?

TT system


Or maybe you can report the 70 volt difference as a fault to the
electricity supplier.

Not spec'ed. Where we are if it's on that's an achievement. We are so
close to 253volts it's untrue so that the farm at the end has enough voltage
to at least turn his lights on.
