C-h mcc

[djcrzysounds@yahoo.com]

Not sure if this should be in here or in the NEC section but I figured this would be a good start. Got a call for a bad starter today at a chemical facility. Has a newer MCC 10-12 Yrs old with C-H Advantage starters... I don't like the starters and I don't like the fact that the buckets house 2 disconnects and starters each (for the smaller buckets).... Was there a code change that stated that an MCC could not have more then 1 disconnect in each bucket? And either way... how does everyone work in them? with both disconnects locked out it was tight spacing inside there. 2 Control Transformers, 2 Starters and a terminal block across the front not fun.

Try working on an AB halfspace Size 1. There are many others. I think that with the new emphasis on NFPA 70E that when the starters need to be worked on - anything else than connecting power and control leads - it should happen on the bench. It may still be crowded, but somewhat easier. Feel your pain, man...:smile:

Westinghouse started the ADVANTAGE starters, it was a derivative of the space program, a great idea but further development and refinement seem to be dropped as Eaton started the IT line that did not incorporate all the great ideas.
