I have a 3 phase 10 hp Kellog-American compressor but KUB won`t give me 3 phase 2 poles from my house. Even To get 2 phase to my barn they want to set 3 poles since the power lines are on the other side of the street and won`t even talk to me about underground. I have a 60 amp 220 ran underground from the house but I think I would need more for a 220 compressor, lights and hopefully a welder. My elec bud says putting a 10hp 2 phase motor on it would not be economically feasible and would probably pull 60 amps on start up and a pony motor would not be either. So how come I can`t stack 2 5hp electric motors on one belt? Kinda last resort would be using a gas motor probably run on natural gas. What size gas motor would be equal to a 10 hp electric? KUB has about made me mad enough to get (or make) a natural gas powered generator to run the barn. What size generator would comfortably run the barn?? I have an old 4 cyl inline water cooled Kohler gen unknown size that I probably could get running on natural gas that would probably run lights and welder and with the Kellog-American running on nat gas I could tell KUB to shove it except for paying them for the nat gas. Sure wish Tessler would have perfected wireless electricity.
Any answers or ideas would be appreciated.

Sir: it is my understanding that batteries must be used with solar cells. I do have 6552 sq ft of roof area. I figure 19 12V batteries in series would be ~ 220V but how many banks of 19 12V in series would I have to parallel to get the 200 amps I would need to operate for 12 hrs and how many solar panels to keep charged? What size of inverter do I need to change the dc to min 200 amp ac?

Cover the roof of your barn with solar panels, arranged to form the letters "SCREW U KUB", and run your stuff off the array.
Or arrange the panels any way you need to get the amount of power you need.
Then do the same on your house.

Sell the 10hp and use the proceeds to buy a unit that will run on your existing electrical. Atleast you will have air.

Ditch the three phase compressor on Craigslist and find a decent 220 v two stage with built in motor starter. You can run a five horse two stage compressor off of a 30 amp two pole breaker. Run your lights off of a 10 amp single and your 120v outlets off of the remaining 20 amp circuit. You just have to kick your compressor breaker off when welding. At my vacation place I have to choose between the tig welder and the air conditioning. Although if I need the AC I usually don't feel like welding ;)

Military surplus is not designed to be economical. Taxpayers can afford it. Much military cannot be directly used without conversion. Different strokes for different folks.

Chuck, My whole shop runs on a 100A service on an underground line I ran from my house. The 100A breaker is the same physical size as any 220V breaker.
I run a rotary phase converter I built from plans on the internet and run all my three phase stuff from the 5hp converter. Three phase is 'good chit' as my Swedish buddy says. But you may not need it for anything else.
Some options.
1- Run a larger underground from your house...I assume you have a 200A service. Once you get that you can decide if you want to do a 3 phase converter or not.
2- Put a 5hp single phase motor on the compressor. You'll want to run a smaller motor pulley that will cut the compressor speed by half. This will let the smaller motor turn over the compressor. This will also cut your compressor output and NOISE by half but 10 HP of air is probably more than you need. A 5hp motor is going to pull a little less than 30 amps by itself.
3- Decide if you want to only use ONE large tool at a time. That is, if you're welding, you've got the compressor turned off, etc.
4- Add up the amps your lights and other constant on devices used all the time. Subtract that from your 60A service (or 100A) and see what's left. If you have enough left, you could run the compressor OR the welder.
5- Investigate a rotary or even static phase converter for your 10HP compressor. 10HP is a lot of air. I have a commercial grade 5HP two stage unit with 200 gal of air storage. I use a lot of air when doing body work and using sanders and grinders and such. I could use a bit more when I'm have a bunch of people in the shop working. When it's just me 5HP is fine.
My shop has grown by 300% since I built it...up to 4000 sq ft now...and while I get by fine working alone, every year I have a metal shaping gathering and have up to 40 folks working on EVERYTHING at once. I worry that something may trip but have never tripped a breaker even when the compressor, lights, a couple welders, machine tools, etc, are all going at once. Just lucky I guess.
6- Or, you could put the Kellogg up for sale and get a smaller compressor. Kellogg American is a really good industrial brand. If it's not worn out, it will run forever and ever.

Two 5 hp motors would pull as many or more amps than the 10hp motor.

You might look around and see if you can find a used Phasemaster. rotary phase converter. They aren't cheap, but if you can find a broadcaster who relocated his plant closer to three phase availability, or who finally had lines run, you might find one just sitting and get it for cheap.

Chuck,
This may sound nuts but how about an 6000 watt Onan to run the barn and a 10 HP petrol engine to drive the compressor. Harbor
freight sells an 11 hp gas engine for $299.99 on sale.
Regards,
Rob

Did I mention it was free? I have thought of using the 4cyl Kohler gen on natural gas and run a belt off it to run the air compressor at the same time. Have even thought of a military surplus gen but have never seen anything military that was economical.
