Bob, there is one condition for an indoor tap exceeding 25' for a high bay building you forgot about that one. Of course this tap has the "qualified persons" caveat. Back to our 10' tap rule: If I'm wrong on this one, I would like to know. My understanding is based on information from Jim Pauley of Square D. I think that what he taught that day made sense. So if you are installing a tap that requires a 600 amp switch, and the load is only 410 amps, I guess I'd put in an 11 foot tap :-) Maybe some of our more learned monitors and book writers will express their opinions. Good to spar with you Bob.
