Cl 8.3.5.2 and 8.3.6.3
Insulation resistance and earth continuity verification limits
The test results and test schedule tools read the lowest insulation resistance and the highest earth continuity resistance a circuit may have.
Verified: read against the printed standard, pages 421–423. Checked 26 Sept 2026.
Units: Min mohm MΩ, Max ohm Ω, Test voltage V V
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
