We are to replace one main service switchboard (fed out of utility xfmr) in one building by a new switchboard. The new switchboard shall be located in new central plant across from old building. We will back-feed all exiting panels in old building from new switchboard? What is the best way to accommodate this with min. power interruption time?
Should we add a new utility xfmr on site and feed new switchboard from this xfmr first before disconnect and re-feed existing building?
The new utility xfmr maybe same size as old one that currently feed this ld switchboard... so it may not a cost saving but can eliminate power shutdown time to the building. Thanks!
