National Grid disconnected our 200 amp entrance and hooked us up to the new 400 amp entrance today. The upgrade was needed for a new RO (yet to arrive) listed for 106 amps that would take our overall load to 198 and so we needed to do something. We also converted from over head lines with a mast to an underground run of 270' from their pole, that warm week we had at Christmas took a lot of frost or it might have been a lot tougher to do. Nice to have that behind us and be ready for the new machine.
