A metal raceway section in a feeder is not reliable for grounding continuity. What should the installer provide?
- AA neutral bond in every downstream panel
- BPaint across the loose fitting
- An approved continuous grounding path
- DA smaller phase conductor
Why C is correct
Feeder faults require a low-impedance path back to the source so the protective device opens. An incidental metal contact or downstream neutral bond is not an acceptable substitute for an effective equipment-grounding path.
