Welcome to our forum.
My intent was to help Mike understand he may well have more (cheaper) options than a total service upgrade. So Mike, call in an electrician so you know exactly where you stand.
Hi! I agree Brewman that the service entrance size is a key component. Also agree this is not stuff for novice homeowners to tackle and Mike needs to call in an electrician to advise him (read the "Caution" at end of my prev. post.)But I don't think we should diagnose whether Mike needs a complete upgrade or not via internet forum. He needs a qualified pro to take a look. You're right to think about Mike's SE size, mechanicals (elect vs. gas,) etc. However, the actual calculation for allowable total load on a given SE size is fairly complex (I'm talking about the NEC calculation) and takes into account more than just the size of the main breaker/SE cable.My intent was to help Mike understand he may well have more (cheaper) options than a total service upgrade. So Mike, call in an electrician so you know exactly where you stand.
