|We are installing more roof fans in my building and we are using SMC-3 soft starts to run them. Where there are several fans close by in a group we were thingking of pwering them from a local MCC that has lots of free buckets.|
One of the guys here has a large bucket that has a nema reversing starter in it and he wants to remove the reversing starter and put 4 soft starts in it with start stop pushbuttons on the front of the bucket and have a 480 x 120 trans former in it for control voltage.
This will all fit and work but is it correct and legal? I don't think so but he says it is and has been it much longer than I have. Just want to know what is correct?
I thought it was only supposed to be one motor control per bucket. In this case he is planning to use the bucket as a small control panel?
