The requirements of ? shall apply when the arc flash PPE category method is used for the selection of arc flash PPE.

• A. 130.7(A)
• B. 130.7(B)
• C. 130.7(C)
• D. 130.7(C)(15)

Answer: (D)

The important idea here is that when you choose arc flash PPE using the PPE category method, there is a specific set of requirements that governs how that method is applied. The category method uses predefined PPE categories to determine protection levels rather than calculating incident energy, so its use is tied to its own rules.

That’s why the correct reference is the subsection that explicitly states the requirements that apply when the PPE category method is used. It serves as the umbrella for all the category-method specifics—how to apply the categories, what PPE ratings are appropriate, training and labeling expectations, and how to document and implement the protection plan. If you’re using the category method, you must follow those particular requirements rather than mixing in standards that apply to other approaches.
