Plugstrips in IT racks often have internal protection to protect the receptacles, especially when the rating of the overall strip is >30A.
These plugstrips that I'm concerned with, are not listed as multitap like a traditional small unit, but they are listed as IT equipment, UL 60950.
There are large plugstrips in the 60 - 100A, 3 phase range that have many sub-breakers, approaching 21 or more sub-breakers. These are generally considered suplementary protection.
Whether they have breakers or not, since they are in a rack and their primary purpose is that they have recepticals to plug in computers, they are not required to have working clearances. With so any breakers, at some point I think they should be considered like Panelboards and not just breakers in IT equipment.
I wondered if anyone has run into this condition?
