I know this has probably been discussed to death, resurrected, then discussed back to death, but for the life of me, I can't find it.
I'm moving some equipment into my garage at home, which currently has a fairly undersized electrical service. I plan on upgrading the house to 200 amps, and will be putting in a separate subpanel of a yet to be determined size (for a combined electric service probably in the 400 amp range.)
Going into the garage is:
1. 7.5 HaasPower CNC, three phase
2. 3/4 hp Saw, three phase
3. 1 hp Surface Grinder, three phase
4. 1 hp Compressor, single phase
5. 1 hp Belt Sander, three phase
6. 1/2 hp Pedestal Grinder, single phase
At most, I'd be running one of piece of equipment while the CNC runs.
I don't have, and cannot get, three phase power at the house, so I'm going to need a phase converter of some variety...right? Looks like I'll need an RPC rated for at least 15hp, correct? I don't know how the phase perfect units are sized, but I'll guess I would need at least 15hp there as well.
I have a basic understanding of how these types of things work (magical pixies make spindles move) but I was curious about power consumption. A rotary phase converter will have a decent sized motor running all the time, correct? I see that they list the 'cost to run per hour' on some of the models I'm looking at - does 23 cents an hour sound realistic? Is it crazy to think just the electrical cost of running the equipment will be a couple of bucks an hour?
I see American Rotary is selling 15hp units on FleaBay for $1049, and I can find a Phase Perfect PT-330 online for $3390. Am I missing something in how I might make up the $2341 difference? Power savings? Hassle?
Is there a better option than American Rotary for an RPC, or Phase Perfect?
