Can electrical equipment explicitly configured for 3 phase 4 lead be used contained by a 3 phase 3 rope application?
Answers:
yes
I assume you mean a 3 phase 3 flex feed and the equipment needs 3 phase 4 lead with all the phases at equal voltages. That would require a delta - wye transformer.
There are also 4 lead deltas out there where one of the delta windings is split and grounded at the mid point.
He means 3 phase with no dull.
Generally no. The neutral is there to get difference currents, ie, if the 3 phases are not loaded exactly the same, there is a difference current and the indeterminate carries that.
you should explain more nearly your 3 phase , 3 wire system !
YES
yes, electrical equipment that is configured for 3 phase 4 flex could be used in a 3 phase 3 wire application but the nouns must be three phase balanced one.
