Hooking up a 3 phase forklift charger. Does it matter if the building power is Wye or Delta?
Hi, I'm Mike and I'll be glad to assist you. No either will do.

I should have stated it is a used forklift/charger already wired for 4 wire 20A 480V. Would Wye or Delta affect the charger as far as the settings go?
Check the nameplate. The difference in a 4 wire deelta and a 4 wire wye is that the neutral will be 277 to each phase on the wye and will be only 208V between the neutral and 2 of the 3 phases on a center tap delta. You need to know what the charger needs for sure to answer the question correctly. Is the fourth wire a ground or a neutral.
