Hi all,
I just purchased a phase-craft 5hp RPC panel, and am getting ready to hook it up to my 3hp 1140rpm idler. In the instructions, it recommends to install:
1) a fuse or breaker box between the panel and the equipment for overload protection
2) overload protection going to the idler motor
My questions are:
a) is (1) satisfied by a magnetic starter on the load machine? A breaker box will be in the plan once I branch out to more than one machine, but is it reasonable to wire an outlet to the output of the RPC, and connect a plug directly to/from the mill's mag starter in the meantime?
b) The RPC idler is an 1140rpm 3hp 3ph motor, with an FLA of 10.6a @ 220v. I have a 30a rated fusible safety switch that I plan to hook up between the RPC panel and the idler. I don't plan to use it as a switch; I'll leave it "on" and just use it for the fuses it houses. What size of fuse should I install? 10amp fuse, based on the FLA? Or does it need to be oversized because of the load from connected motors?
Thanks in advance,
Lee
