Help with Phase converter size?

[chester7]

I have a phase converter I got many years ago but forgot how many hp it is and there is no id tags on it, anyone here have a guess to what size this might be its original color would have been gray eh? Im thinking its either a 2hp or 5hp but not sure i used it to run my mill that has a 2hp 3ph motor. I tried contacting where i bought it and they were no help at all eh.

Above is a link to building RPC's you may be able to deduct some information by checking out your capacitors sizing and determine what HP they may be best suited to.

More or less look at the nameplate of the idler motor. You can use it for machine motors less than or equal to that of the idler motor.

Edit: that does not look like a 5hp motor to me...more like a 1 or 2hp, probably be OK as the mill starts under essentially no load. It looks like its mounted right to the mill, are you intending to run something else with it?

I think it was a 2hp also but cant remember. No it will still be used for the mill but I just built a new shop and want to get the right electrical wiring to the phase converter thinking 20a 220v / 12-2 wire should work if a 2hp eh
I had it in my garage with 40a 220v and I think thats a bit overkill eh
Thanks
