The first section of Article 130 states that all requirements apply whether a(n) ? analysis is completed or if Table 130.7(C)(15)(a), 130.7(C)(15)(b), and 130.7(C)(15)(c) are used in lieu of an incident energy analysis. What analysis is being substituted?

• A. Fault current analysis
• B. Short circuit analysis
• C. Incident energy analysis
• D. Thermal analysis

Answer: (C)

In arc flash hazard assessment, you must address the energy that could be released if an arc occurs. You can either perform a formal incident energy analysis to calculate that energy (in cal/cm^2) at a given working distance, or you can use the pre‑computed PPE tables in 130.7(C)(15)(a)–(c). The statement is saying that all safety requirements apply no matter which method you use. The analysis being substituted is the incident energy analysis—the detailed calculation of incident energy. The table method provides equivalent protection without doing the calculation by giving PPE categories and arc‑rating requirements based on the same hazard factors. The other options aren’t the substitute here because they’re not the method NFPA 70E uses to replace an incident energy analysis; they’re different kinds of analyses (fault current, short circuit) or not related to arc‑flash PPE selection.
