"transposing the Mains wires at the point of intake"
Reminds me when some dude used the grounded (neutral)conductor to supply a phase in a Bronx, NY candy store, because that phase was grounded to the system somewhere, everything in the store was reversed polarity at the receptacles, for examples.
Trumpy, have you ever worked on systems here in the USA?
Please descrive the Wye systems used in your area.
