Except for me, with a SWER line. Just one wire to the pole and
Earth doubles as Neutral. Very common in rural Australia. I do
wonder what would/will happen if everyone on SWER buys an electric
car and tries charging it on the same night, it's a lot of juice to
pump through the ground, and if the voltage drops would it all
start oscillating as the charging circuits in the cars cut in/out?
