I have the 20HP Phase Perfect which is supplied by a 100A, 220V PH1 Breaker. My compressor and Dust collector are 5HP and 4HP. Both are single phase. I would keep the DC and Compressor single phase because they're machines that serve other machines. I also have a Wide belt, in order to run it I have to have the compressor and DC operating. My shop has 7 Machines that are 3 phase, for your own info, I can leave the planer running at 10hp and turn the table saw at 7.5hp on and off. The issue I do have however is that I used a power distribution panel that is fed by the Phase Perfect, and then feeds power to the 7 machines. My planer has an extremely aggressive motor brake which dumps regen power when I turn it off and affects all the other machines in the shop.
The Wide Belt will blow a small 1 amp Fuse that protects the electronics and the Mortiser has a built in VFD which will trip.. Both are caused by a power spike, both are caused by the planer. I've had electricians ensure the wild leg is on the correct leg of each tool, the issue seems to stem from the PP have a large resistor that doesn't let regen power back in, so it seems to get pushed back out to the machines.
Other than that, its a great set up. My PP is I believe a 2008. Been a great machine. 14 years old.
I didn't think of it at the time, but my setup is very similar to yours in that I kept the dust collector and compressor on single phase. So they don't draw any power from the Phase Perfect while a large 3-phase machine like the wide belt sander is running.
My bandsaw has a DC motor brake, but it doesn't seem to affect the other machines.
