Phase converter going in

The converter is a Phoenix Phase Converter and runs off of a bank of capacitors, which will then feed a breaker panel with 3 phase power. It's on a 50 amp circuit and I'll be using AWG 2 wire from the idler motor to the control panel, 2 gauge from the single phase supply to the control panel, also AWG 2 to feed the breaker panel. I understand that 2 gauge is probably overkill for a 50 amp circuit, but that's what it came with so that's what I'm using.

I'll determine the gauge that supplies the branches once I confirm the amperage draw of each machine, and then use an online calculator to figure conduit fill, so I can buy the right size conduit.
