Which statement is true regarding a plan examiner's need for knowledge of electricity when reviewing electrical drawings?

• A. A plan examiner must have a basic understanding of electricity.
• B. A basic understanding of electricity is not necessary.
• C. They should rely entirely on electricians for electrical drawings.
• D. They should avoid reviewing electrical drawings.

Answer: (A)

A plan examiner must have a basic understanding of electricity to effectively read and interpret electrical drawings, assess how the electrical design impacts fire and life-safety requirements, and verify code compliance. With a foundational grasp of electrical concepts, the examiner can recognize proper layout, clearances around panels and electrical rooms, the relationship of circuits to emergency lighting and fire alarm systems, and how equipment ratings and separation from combustibles influence safety. This enables independent review and proper coordination with electricians, rather than relying solely on them or avoiding the review altogether. The other approaches undermine the examiner’s responsibility to ensure that electrical systems meet safety and code standards.
