I'm installing a multi building system ( large shop / home ) The primary
feed is going to the shop 600 amp @ 480 4 wire. I plan to run a sub feed to
the house with 175 amp 480 3 wire ( 4-0 AL @ 300') to a 150 Amp breaker /
disconnect box. Then to a 112.5 kva 3 phase transformer ( 480 delta to
208/120 Y) At the house I'm going to run a ufer ground and also the
required 2, 8' ground rods. I assume that I will need to bond the derived
grounded connector from the transformer to the equipment safety ground in
the 208 V panel?? or should it be in the service disconnect ( normal place
to bond, but seems like a strange place, as there is no neutral in that
box )
Thanks
