Sounds like an expansion is needed, something along the lines of "not more than 6 feet from the OCPD". That would cover it for sure. FWIW I think a multi-pole snap switch next to the panel is fine, but to clarify the intent some boundary should be set.The CMP feels differently.
This is from the 2008 ROP and makes clear that the CMP does not feel the source is the OCPD. I will admit It does show other people have some confusion on it though.
No, that would not be at the source that would be a 100' away.
Think of it the same way as 'nearest the point of entrance'
I am not going to change my mind, the CMP sees it like I do (or I see it like they did) OTH what you are suggesting is not supported by the words in the section.
