We have a 60 amp electrical service to our home, plus a separate meter for an electric hot water heater no longer in use. There's not a lot of draw in the home--gas stove, gas HW heater, no toys. Then there's an overhead 4-3 alum line that runs about 75' to our well house with a small breaker panel that powers the 1 1/2 hp pump, along with a 6-3 copper line that carries 230 to the barn (shop), and another 10-3 copper line that carries 115 to the shop.
What I'd like to do if possible (without spending the $2000 right now needed to do an upgrade for all this), is to install my 20 hp RPC in the shop. It's static converter/idler motor
combo. It draws 20 amps at idle on three phase, and a guess I got was 30 amps at idle on single phase 230. I also have a 3 hp dust collector, 5 hp table saw, 4 hp jointer, 3 hp jointer, 4 hp air compressor, and I think 2 hp air filter cabinet. There are all three phase. What I was thinking is to start up the RPC with an idler motor where it will draw approx. 30 amps, then have a separate line to run the dust collector, and another to run either the table saw, jointer, or bandsaw--just one at a time. The air compressor can wait to run by itself, as can the air filter, but the dust collector would need to run with the table saw, or jointer, or bandsaw. Is this doable with what I currently have? and how would I set up the circuits? Normally no one is home during the day when I'm using the shop, so theoretically the full 60 amps would be available for use, and I believe the lines are big enough to carry these loads. If I blow the main fuses on the odd occasion I'm not worried about it. Just don't want to be stupid about it.
