Am looking for a web link to supplier of 30MFD / 370AC motor capacitor for my Magnetek pool pump. I have in the past used York Capacitor but they have gone. Also............is this capacitor a start cap or run cap or both? Reason I ask is Grainger has a number of caps on their web site but are divided into start or run. I have motor running as I moved the cap from the spa pump, which is an identical part, over to the pool pump so no major urgency.
