Ok, finally getting down to start to tackling our basement playroom build for my 3 loud kids, lol. My issue is that when the house was built, they only installed a 100 amp panel, and it looks like its only 23 circuits. (Odd number I know) I don't have any free breakers (panel is full) so the electrician gave me a few options: Option A: Full panel install for 200 amp service and 40 circuits, along with an interlock kit for the generator set up. Option B: Install a 200 Amp panel, but keep the 100 amp feed.....also adding the interlock kit. (This would cost less, but not sure how much less) I was originally thinking of a subpanel for the additional circuits needed for the basement, but then run into the issue of not having any free breakers on the existing main for the interlock kit. Basically, I'm trying to determine the drawback of going with option B. For the basement renovation, we will be putting in lights, outlets, and (2) 8' electric baseboards...so I don't need a ton of circuits, just a lot more than I have now. Don't have the quotes back, but I am thinking the upgrade to 200 amp is going to be around $2,000??/seem about right?
