Do you mean a static phase converter, a rotary phase converter or a VFD?

If you don't have a VFD and your machines have their own power switches, you
can keep both machines hooked up to the converter, you don't need a switch.
If you have a VFD its best to use a switch.

been in the past, just pulling the 3 wires from the motor off of the
converter, and plugging in the motor wires from the other machine.

to just switch between the two without having to pull wires. ANybody
know what I should be looking for? Thanks for the help. if trying to
email me direct, email
