Sorry for the poor form in getting back to you. Life, family and work got in the way. I believe that you are right. While we are only using about 40% of capacity currently, we will need to begin using ac units to keep the sheltered workshops cool during the summer. The 4 units will take us over 50% of available power.
I looked into adding extra power and it's way out of our budget. So I think we are going to sell the unit and try and get another paper cutter hooked up instead.
Thanks for your help and giving me the information I needed to make a decision. Let me know what I need to do so that you can get paid.
