I am concerned with the requirement - or not - of having a disconnected device other than wiring terminal block on equipment residing in telco CO's. This would be for redundant -48 Vdc supplies. I have been following the discussion lately and the intent seems to be to provide that - possible through and IEC 309 (?) style connector. However, the design engineer really doesn't want to put in anything except terminal blocks. If I read all the references UL 1950 2.6, 2.6.11, and 3.4 I'm not sure I can justify the requirement for a disconnect closer than the breaker panel. Am I just being a sore loser here? How have any of you resolved the issue. The product is a 300 pound stationary device, can be rackmounted, and it has a redundant power supply which shares current until a failure of the other supply and then takes over the entire load. ??????? Snort ??????? Thanks Gary McInturff
