7.5HP RPC

Probably money well spent on either a component or packaged enclosure with all the components wired in. That way you are not guessing as to the component ratings/specifications.

If I dont have the right capacitors I will order the kit, probaly the same price as ordering the right capacitor.

I just got two 7.5 hp 3 phase motors from my uncle, I’m using the better one for a RPC. I have a 60 amp 220 volt circuit running only the RPC. Will this wiring diagram work. The switch I am using is rated for 7.5 hp 3 phase and I’m using 8 gauge wires for all of it. The highest HP machine being powered is a 3 HP lathe, I hope to be able to run the lathe and 2 HP mill at the same time without having issues.View attachment 464447

I built a 7.5 hp RPC to power my 3 hp lathe.
I bought the kit from the company at the link below.
It came with all the capacitors, contactor, wire, solderless connectors, etc. and instructions. It starts with a simple toggle switch and for 2 years has worked flawlessly.
The wiring instructions were simple.
I did have to buy a 12x15x6" enclosure box to put all the parts into for about $40.
Recently I built a 5 hp rpc for my friend.
It was as simple as the first one.
That is the route I recommend.
