I want to get my HLV H lathe running in my garage. Here is what I have.
1. Hardinge HLV H running a 1.5 hp 440 motor. (no, it is not dual voltage and I don't want to get it rewound)
2 Phase a Matic 5 hp RPC 220 volt.
3. House current is 110. I have installed a 220 outlet in the garage.
4. Hammond 3 phase auto transformer. 240 to 480.
5. one 3 phase 30 amp disconnect switch.
Question is, How do I install? I hear you have to start the RPC and have it up to speed before you switch on the transformer as the transformer adds load to the current. Do I need two 3 phase disconnects, or can I simply use an on/off switch for the RPC, then the 3 phase switch to the transformer? Can anyone send me a diagram?
I already have all the above available to me. I am not interested in going VFD or any of the other available options.
