Although it sure would be nice to have a larger DC!

Currently with only a 40-amp 220 supply to my two car garage, I'm sort of limited as far as power goes.

5hp. Rotary Phase Converter FLA 14.8
2hp-3ph. Dust Collector FLA 5.2
2hp-3ph. Dewalt Radial Arm Saw FLA 5.0

I've never actually tried running all three of these together yet! But in theory it should work?

Figuring that the RPC idler motor should probably never draw it's rated FLA (except for start-up)
it should give me a little wiggle room.

Although math was never really my favorite subject! Using the FLA of 25amps listed above, And figuring that the 3 separate power lines are being generated by the two regular 220 volt input lines.
Working with the numbers, The square root of 3 (1.732) X 25Amps = 43.3 amps.
