Minimum insulation resistance for arc welders incorporated into generating sets
The construction site supply tool reads the minimum insulation resistance for an arc welder incorporated into a generating set. It reports these values only for that case.
Verified: read against the printed standard, pages 38. Checked 1 Oct 2026.
Units: Minimum megohm MOhm
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
