I am presently involved in the design on a copier showroom. The existing electrical in that area is a 100A @480Y/277V & 30A @208Y/120V via a 9KVA transformer. The area is roughly 1200 sq.ft, giving approx 9w/sq.ft. The problem is they are going to have approx 8/9 large copiers, the total load at 208V is approx 16KVA, taking the first 10 at 100% and the remaining at 50% put me at 13KVA which requires a new transformer which hasn't been figured into the budget. They are never going to use all the copiers at once but I don't know of any other demand factors I could use by Code to get to the 30A level. Any ideas or anything I am missing would be greatly appreciated.
Thanks
