Question

Quizplus · Accepted Answer

A "header" is a type of raceway specifically designed to provide access to predetermined cells of a cellular metal floor for electric conductors. Option D is the only choice that accurately reflects this definition. Option A talks about an unbroken conductor connecting individual outlets, which is not directly related to a header. Option B mentions a cellular metal floor, but does not specifically address headers. Option C refers to rigid tubing enclosed in a tubular space, which is again not directly related to a header.
