I have three 20kW 480V 3 phase 4 wire inverters that need to interconnect with a 208V service through a step down transformer. I have been advised not to use a wye to wye transformer, so the minimum 60kVA transformer will have to be 480V/277V wye on the primary and 208V delta on the secondary. My question is this: do I ground the neutral on the primary side?
My guess is no.
I'll hang up and listen...
