if you look at the switch you will see its only rated for 15A and yet Ace wants you to install the puller with a 30A fuse or breaker,
seems to me that switch is going to be an ongoing problem, I have one on its second switch now and when that goes I will be wiring in a foot operated switch that I purchased from another puller Mfg'er
mine has burnt out 2 switches and 1 motor, 1 of those switches was on the second motor too so no change in switches.
I had brought this to their attention and they said they would look into it but I never did hear anything back from them
