The question that was asked of me was,"Could I see any savings in my power usage,through better system efficiency, by changing from the Grounded B phase system to the 3Phase 4Wire system?
What, if any, is the percentage of efficiency, plus or minus,of a 480 volt Grounded 'B' 3 phase 3 wire system as compared to a 277/480 volt 3 phase 4 wire system?
