Thanks very helpful Great link. Cannot determine the complete loads types on this per it age. I know Im pulling 230 amps. per phase. With spikes to 260. The addtional loads Im trying to add is general Lighting and recepts. Printers. Etc. These are inductive loads. Which is another issue.. I am presuming 110 amps.

THanks for response. Happy New Year.
