3 phase question

[machinistnoob]

I would remove the existing wires get the correct 4 color code wiring and rewire it correctly. Get something wrong and it could be serious, it is not only for your own safety but for others. Assuming it is 3 phase power from the RPC and you are driving a 3 Hp motor, you can run 12 or 14 AWG depending on the size of the RPC and if it has a breaker/fusing. There should be no neutral unless you are breaking out 120VAC and then that would need separate breaker/fusing. The power drives and DRO are most likely 120VAC single phase. If there is a transformer, in the control system only the ungenerated legs should be connected to it.

If you use SOOW type wire with a white wire that is carrying current, then you should put some electrical tape (I usually use blue or black) at either end to denote that is not a neutral.
