Thanks for the replies.
lu380, only the 7hp motors are dual wound and the 7hp and the 15 hp motors are kind of a specialized motor, only used in this machine and they are 8000 rpm. The 20 Hp motor does have a bunch of leads, I don't know how many there are but I do know it cannot be wired for 240 as none have been made for this machine that could. IT is a two speed motor I believe 1800 and 3600 rpm. I looked into having the motors rewound for 208 but the cost was high, almost as high as the $7000 price quote. I still don't know why it was so high. A year ago I had seven 3 ph machines hooked with a new 600 amp service brought in one end of my building( its split up between one 400 amp panel and one of the 200 amp panels) and was still under seven grand.
I've called five electricians, one flat said he didn't know that much about hooking up transformers. WTF? is it really that specialized?
One guy came out and looked at the machine and said: " Whoa! Dude, thats alot of wires! Nice pretty colors too!" When I asked him for an estimate he just said "I don't know man, THats alot of wires! I lost all confidence in him, however cheap he is.
The third guy came out and never called me back, I guess he wasn't interested.
The fourth guy, a friend of mine, wanted to do it but his wife just had a baby and he's only working about 20 hours a week right now. He has a maintenence contract with a local business that has him tied up right now.
THe fifth guy gave me the $7000 estimate. He didn't have a new panel or service listed on the estimate.
If a 50kva transformer will work, I'll look around for one. I called an electrical supply house that I have an account with and they suggested 47kva and quoted a price of $970 plus freight. So I'm guessing around $1200 for the transformer. What I would like to do is get all the stuff here and get my uncle to come in and hook it all up. He wants to come here and tinker in the shop anyway.
