   So what do you get down the cable, (assumed AC volts)

-55, 0, +55, 230

-110, 0, +100

0, 110, 230

0, 230 and provide your own transformer for 110volts

or something else and do your own conversion? Don't forget to include the
cost of providing and upgrading transformers in the cost calculation.

   Our 230volts is of course one phase from a three phase supply, together
with the centre tap from the three phase transformer, and individual single
phase premises are connected to different phases in an attempt to balance
the load.
