[RE-wrenches] SolarReady Service Panel vs adding Supply Side connection?

[Jeff Clearwater]

Hey Jay,

Yes so you were on to it - but with the addition of having that 
downstream of a separate 200 AMP meter box and 200 A Main that works :) 
Otherwise PG&E would call it a 400 Amp service which for commercial 
accounts means having to have CTs for the metering.

Thanks!,

Jeff
