A metal cabinet contains service conductors, their splices, and current transformers (CT), and is located upstream of an 800-amp service disconnecting means. The CT cabinet has only PVC raceways entering and exiting the enclosure, and the engineered drawings do not show any supply-side bonding jumpers in the PVC raceways. Is it correct to assume that this metal CT enclosure must be connected to a supply-side bonding jumper? If so, what is the correct size bonding jumper? Should supply-side bonding jumpers have been included in the drawings?
Although NEC Table 250.102 (C)(1) provides sizes of supply-side bonding jumpers, there seems to be no specific text section that references this table for metal enclosures. I have looked at 250.80, 250.92, and 250.102 (C). Can you help me connect the NEC dots to size supply-side bonding jumpers to metal CT enclosures?
