Capacitor Hazards Evaluation

 

Capacitor Hazards Evaluation per NFPA 70E 2021 to 2024 and CSA Z462 2024

Comply with the latest safety requirements related to stored capacitor energy hazards such as shock, thermal and arc-flash blast! The capacitor stored energy hazard evaluation is fully integrated in ETAP 20.5 (and above) and can be used to generate warning labels for capacitor hazards. Evaluations are based on Article 360 and Appendix R of NFPA 70E 2024. Tool also supports calculations based on Annex W of CSA Z462 2024.

Features include:

  • Evaluation of Capacitor Stored Energy Shock, Thermal and Arc Blast Hazards:
    • Evaluation capacitor discharge time against different discharge standards such as:
      • NEC 2020 to 2023
      • CSA C22.1-2018 to 2021
      • IEC 60831-1, 60871-1-2014
      • IEEE-18-2012
      • NFPA 70E 2021 to 2024
      • CSA Z462 2024
    • Stored Energy Arc-Flash Hazard Calculation
    • Hearing Protection Boundary
    • Lung Protection/Collapse Boundary
  • Consider the effect of capacitor stored energy (connected or disconnected from power supply)
