"Sufficient access and working space shall be provided and maintained about all electric equipment to permit ready and safe operation and maintenance of such equipment."
Is what it says first, and later lists the parameters....
"Working space for equipment operating at 600 volts, nominal, or less to ground and likely to require examination, adjustment, servicing, or maintenance while energized..." - You can shut off a box, and it very unlikely that you would need to do all of those things hot, like you might for a panel, especially a main panel. As far as "F" goes, I (Can't) think of anything else...

I never quite understood why an HVAC disconnect needed to be serviced while energized but I have always been told it needed full working space. If we changed the rule on that the world would spin out of orbit, into the universe and life as we know it would cease ... or so we have been led to believe.
