Q: According to NEC 250.30(A), if a separately derived system (SDS) is supplied by a generator, where must the grounding electrode conductor (GEC) for the SDS be connected?

To the grounding electrode system at the generator's location. — The GEC for a generator SDS must be connected to the grounding electrode system at the generator location, ensuring proper fault current paths.

Q: In a building with multiple service disconnects, what is the NEC requirement for bonding the metal parts of the electrical raceways and equipment?

All raceways and equipment must be bonded to the grounded service conductor at each service disconnect location. — All metal parts of raceways and equipment must be bonded to the grounded service conductor at each service disconnect location to ensure a low-impedance path for fault current.
