I recently purchased a RPC with a 3HP Lincoln motor. The unit has a Dayton 5X847M start relay, a GE 6X550 voltage sensing relay and (2) start capacitors wired in parallel with a single bleed resistor. The RPC starts right up and runs quiet. The unit will power my 2HP Bridgeport mill just fine but causes my 1.5HP band saw to trip the manual switch after about 10 minutes of operation (the heaters are hot to the touch). The unit will not start my 1.5 HP YAM lathe - just growls. The output voltages are 240, 205,205. A scope shows two phases at about 180 and the third at 60. I think some run capacitors to balance the voltage and phase shift might help the situation.
I would appreciate some general direction on run capacitor sizing. Any other insights are welcome because this is my first experience with the RPC.
Thanks in advance,
