Ok...so my breaker box is completey full with no available space for a new circuit. Additionally, I only have 150 AMP service, which I think is unusual for a new home ("cookie cutter" home)...isnt 200+ normal? So, how do I go about adding a new circuit given this situation? Do I need to upgrade my service to 200 AMP? Or could the builder have just thrown a 150AMP master in the box to save a few bucks and simply replacing this with a 200 AMP one would work? Obviously I would need an electrician to do this, but is there a way to test without having to call an electrician? Will the power company know this? Any other things to check that I've missed? Thanks for all your help.
