Thanks for the responses. I’ll go the extra two miles on this… really trying to do the long-term good.

I’ve installed an additional single phase sub-panel in the work shop… creating more power for a shared shop / living space (above the shop): I’ve added electric infrared heat to the shop, and will need HVAC, stove, and water heater for the living space within two years. I’ll centralize all single phase power onto a single panel at that time. From this new panel (100A), I’ll feed a Phase Perfect PT-355 (100A single-phase in, 65A 3-phase out). The output will go to a 3-phase panel… providing multiple circuits for the machines – at max. load, one machine draws 30A, the other 20A. Since these are a J/P and TS, respectively, they will not run concurrently. I’ll convert my dust collector to 3-phase, and this draws 20A. From a concurrent load perspective, I’ll have between 40A – 50A on the phase converter.

I’m not sure if this subject is of interest to the Forum Members; however, I found precious little information to help me work through this; and I hope this will help other members who are considering three-phase. This is an expensive solution, no doubt.

Thanks, again, for your comments and consideration.
