Where documented safe switching procedures are established and maintained and the installation is monitored by _____ individuals, the disconnecting means for a building supplied by a feeder can be located elsewhere on the premises.

• A. licensed
• B. qualified
• C. trained
• D. certified

Answer: (B)

The essential idea is that remote switching is allowed only when there is a documented procedure and supervision by a person who has the appropriate level of electrical expertise. When switching procedures are documented and the installation is monitored by someone who is qualified, the disconnecting means for a feeder-supplied building can be placed elsewhere on the premises because the supervisor can accurately assess hazards, enforce safe switching, and ensure proper lockout/tagout and coordination.

A qualified person, per the NEC, is someone with the skills and knowledge related to electrical equipment and who has safety training to identify and avoid hazards. This level of competence is what the code relies on to authorize more flexible or remote arrangements, because it ensures that switching can be performed safely and that the risks associated with energizing or de-energizing feeders are properly managed.

Licensed, trained, and certified describe credentials or training, but the NEC specifically uses the term qualified person for this context. A licensed individual may or may not have the exact equipment-specific knowledge, training, or awareness of hazards required to supervise switching, and “trained” is too generic to satisfy the code’s defined role. “Certified” implies a formal certification, which the code does not rely on here.
