I don't have a pole can... I live out in the woods and all the services are underground and I'm serviced with a pad mounted transformer that only feeds my house and shop. I have a 200 amp service that is split between my house and the shop and both have 200 amp panels with proper size wire. I can spin up my lathe 5.5Kw spindle from 0-6,000 while the mill is running and never have I seen the lights dim, well when I ran the garage from some direct bury 10ga I could make the lights dim but not since I built the shop and installed proper wiring.
Is the encoder disk problem one of cam or cad? John On 5/29/2012 2:45 PM, gene heskett wrote: > On Tuesday, May 29, 2012 03:10:01 PM John Thornton did opine: > >> Where should the 208v be?
