If branch circuits requiring equipment grounding conductors are supplied by a feeder, what is required of the feeder?

• A. It must include or provide the equipment grounding conductor.
• B. It must be insulated with corrosion-resistant coating.
• C. It must be colored green only.
• D. It must be isolated from all grounding.

Answer: (A)

The essential idea is that a feeder delivering branch circuits that require an equipment grounding conductor must itself carry that grounding path. This ensures a continuous, low-impedance route to the building’s grounding system so that any fault on downstream equipment can trip the protective device quickly and keep people safe. Therefore, the feeder must include or provide the equipment grounding conductor. The other options don’t address grounding: insulation coating isn’t about fault protection, color alone doesn’t guarantee a grounding path, and isolating from all grounding would remove the safety path entirely.
