Hi all,
I'm in the process of finalizing two combination motor starters to run my rotary phase converter and radial arm saw. I'm using an Allen Bradley NEMA 1 starter for the RAS, and an Allen Bradley NEMA 2 starter for the RPC. The NEMA 1 box has a 509 Allen Bradley contactor and the NEMA 2 box has an Allen Bradley 709. Both will be using Allen Bradley 800 series start/stop switches.
Here's my question - in my parts bin I have an NOS Allen Bradley X-343858 Control Transformer. What are the guidelines for when to use these? I know they are supposed to stabilize the control circuit current - but on what type of start circuit is this actually necessary? Since I"ve got it - I was thinking that my RPC might be the one to put the transformer on, but these things are cheap - so I can get another for the RAS if it actually offers any advantage whatsoever. If there is no advantage for either piece of equipment, however, I'd happily leave it out and save it for a device that may need it down the line.
Thanks!
