I'm trying to get a 2nd opinion...
I've got a 200A main panel now in a residence, with a 150A breaker. The addition will double the size of the house (1500 to 3000 sqft) and add a 2nd 3-ton heat-pump with emergency-heat backup, which alone sucks up the spare 50A on the panel. I can just *barely* justify the minimum service load calculations to fit on this 200A panel, but it's close- to the point where if I add the refrigerators into the calcuation on a dedicated circuit vice assuming them included in a 1500VA kitchen circuit, the calculations fail. Do you think we'll be OK with the 200A service, or is a call to VEPCO in order to get the service upgraded? I'd really rather avoid having to upgrade the existing main panel, but it seems to be quite a risk.
