The project being worked is a class 1, division 2 area. The wiring method is with type TC-ER cable. 501.30(A) states that "bonding jumpers with proper fittings or other approved means of bonding shall be used. Such means of bonding shall apply to all intervening raceways, fittings, boxes, enclosures and so forth". The section also refers you to 250.100 which refers you to 250.92. My question; When using type TC-ER cable methods do the cable gland fittings (CGBs) need to be installed with a bonding bushing and jumper to the ground?
