Thanks for all inputs. I am looking for actual inspection results. In our case it is a an existing prefab e-house where we need to install 600V MCC's front to front, so the spacing considering draw out equipment is critical. The situation is that draw out equipment (starter buckets) become de-energized when extracted only 2-4 inches, but would take a full 1' to take it out of the mcc. I got feedback from a CSA inspector at manufacturing facility and he approves to consider only 2-4 inches to have the bucket de-energized. I am asking if this interpretation is ok or there might be another inspector that has a different interpretation. The conservative interpretation of full extraction doesn't allow installation of another MCC in the e-house, that is why I need to check if we can compromise on a more optimized interpretation.
No actual inspection results for you, but reading that rule again, it specifically says the 'disconnected position'.
I'd run it by your inspector, but I think he may ask for the 1M, plus the 40cm X2 ... 1.8M total (because you could have both buckets across from each other disconnected)
