Dan,?
I too am running a Phase Perfect PT010 (build year 2020) and it has been great. It runs on a 80A 240V 1Ph circuit breaker, I think the next size up requires a 160A breaker, which is greater than your sub panel so probably a "no-go!". I regularly run a 4hp 3Ph RL160 along with my 7.5hp 3Ph KF700SP, or my 7.5hp 3Ph 16" wide belt with no problems, I expect the same when I receive my 7.5hp 3Ph FB710 and 10hp 3Ph shaper.
As David Best writes, the staff at Phase Technologies are great to work with, and were very patient with me as I worked through which appliance to order and how to set it up.?
Best wishes,?
