Coefficients for the intermediate average arcing current
The arc flash tool reads the arcing current coefficients for each electrode configuration at 600 V, 2700 V and 14 300 V.
Verified: read against the printed standard, pages 23 (PDF 24). Checked 1 Oct 2026.
Units: Voc V
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
