We are installing a 1600 amp service with (5) 4" PVC conduits with steel galvanized elbows from the pad transformer to the pad mount CT cabinet. From the CT cabinet we ran (5) 4" PVC conduits to the pad mount MDP... all PVC (no steel elbows). Do the steel elbows entering the bottom of the CT cabinet need to be bonded with grounding bushings to the neutral in the CT cabinet?
FYI... The utility company is supplying the conductors from the transformer to the CT cabinet and we are supplying the conductors from the CT cabinet to the MDP - 5 sets of 400 MCM
 
NEC would require these elbows to be bonded, I can see where its a bit confusing, you are installing raceway, POCO is doing the conductors. What do the POCO standards require?

It would depend on where the service point is. If they fall under the NEC, there is an exception for bonding isolated steel elbows but I believe they have to be a certain distance underground. I cant recall what code section that is.
