A feeder supplies a panel where both grounded and ungrounded conductors could be confused with another voltage system. What should be provided?
- AOnly a handwritten jobsite note
- Permanent identification of the conductor system
- CA larger equipment grounding conductor for the feeder and operating condition described
- DTemporary tape on the panel cover
Why B is correct
Where multiple nominal voltage systems are present, ungrounded conductors require identification by phase and system, with the method posted or documented as required. Identification supports safe operation and maintenance.
