Re: workstation wiring 605.6 & 605.7
Neither. Use only single pole breakers. Why would you want an overload on one circuit to trip three or four CB's at the same time?

Article 605.6 & 605.7 states "Multiwire branch circuits supplying power to permanetly connected (freestanding) partitions shall be provided with a means to disconnect simultaneously all ungrounded conductors at the panelboard where the branch circuit orginates"

Wow! Guess that I missed that change in the 2005 NEC. Am I alone here in thinking that this is a bit ridiculous? I understand that it's for the additional safety factor. But we've installed hundreds of these partitions, many with 6 circuit feeds. Do they make a six pole handle tie?

If we take it your way we have real trouble a s group of interconnected partitions can have many feed locations.
:roll:
I think the way it is worded it only has to disconnect simultaneously the conductors of one MWBC at a time.

I am also in agreement that the code should not add requirements that are only designed to protect those performing unsafe work practices.
I was recently made aware of an experiment made at the local community college here in town. A student painted a sign and posted it on the wall next to the door entering the library. The sign read, "do not touch this sign".
A hidden video recorder was setup to catch people walking into the library. During the 2 hour recording 65 students touched the sign. 84 entered the door during that time.
What does that tell you.
