RVSS = Soft Start??
We just put a soft start on a 250 hp motor that had possibility of wye delta start. SS instructions indicated that we could parrallel the windings and reduce the wire size to the motor by 53%. We did not do it because the customer had 3/0 wire already, but if I understand it correctly we could have run 1/0 to each set of windings. There was a parameter that needed to be changed. We had it wrong and the SS shut us down before you could blink.
