What is the minimum arc rating of category 2 PPE?

• A. 8 cal/cm2
• B. 4 cal/cm2
• C. 2 cal/cm2
• D. 16 cal/cm2

Answer: (A)

Arc flash PPE categories specify minimum energy protection. Each category is tied to a tested arc rating, measured in cal/cm2, that the gear must withstand. For category 2, the baseline protection is 8 cal/cm2. That means any PPE in this category must be rated at least 8 cal/cm2 to meet the category’s requirement. Ratings lower than 8 cal/cm2 don’t qualify for category 2, while higher ratings are possible (and would place you in a higher category). The other options don’t fit category 2: 4 cal/cm2 corresponds to category 1, 2 cal/cm2 is below category 1, and 16 cal/cm2 isn’t the standard designation for category 2 (it would indicate a higher protection level).
