Tables 3.1 to 3.3, 6.1 and F.1 to F.4

Battery system hazard classes, decisive voltage class, arc flash energy, PPE level and consequence level

The battery arc flash tool reads the hazards and fire level of each chemistry, the decisive voltage classes, the PPE levels and consequence levels by energy, the home limits, and the Appendix F rows its equation reproduces.

Verified: read against the printed standard, pages 25–29, 97, 140–144 (PDF = printed page + 8). Checked 1 Oct 2026.

Units: Voltage V V, Bolted ka kA, Arcing time S s, Incident cal cm 2 cal/cm2, Boundary cm cm

These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
