Re: Load Calculations
I had temporarily moved this question to an area open only to Moderators. The reason for the move has been resolved, and I am moving the question back to the active area .
On behalf of the Forum Owner and its Moderators, I wish to offer a sincere apology to ?extreme,? both for the inconvenience and for the delay.
I would ask that the forum members give this question your due consideration, and that you provide whatever assistance you can.

Re: Load Calculations
You have not listed any of the loads. I assume that there is no electrical heat. Range, W.H., Dryer? You are at a 200 amps service by your caculations. Add the sq. footage of the addition and estimate loads and re-run the cacls. You may be up to 225 amps. If you don't have electric heat I doubt that you will have to go to a 400 amps service.
