I have a ongoing thing with my boss about bonding, we are doing a 450ft run of 4/0 and #2 ground. Going though 4 j-box's. There are no concentic k.o's all are punched, I say we should use bonding bushings not just locknuts for the bond. He says just plastic bushings. Who would be right. Thanks Sam

2005 NEC 250.92 is for services . As this is a feeder . (250.97) deals with Bonding over 250 volts to ground. If this was a 120/240 or 120/208 volt. Bonding bushings on a feeder would not be required Even if concentric or ecentric was involved. IF they were in good condition.
