KJay, thanks for the reminder. This unit I may be wiring in going on a possible 250ft. run. The #4 I'm figuring is good for 85 amps(75 degree column). Hope that will be sufficient. Very good thing to remember though. Can't always go by just what's on the nameplate, and I'm finding out on industrial wiring and commercial, a person can go bankrupt real quick if you don't do the right math:(
