long time listener, first time caller.
I've got a 65 year old home that was wired in a way that makes no sense. 10 recepts on one circuit, 2 recepts on another, weird stuff.
There is no 14 gauge wire in the entire house, all 12/2, yet all 120 is on 15 amp breakers. For the first 64 years was fine, but I recently put a little home office in the basement, which meant an extra desktop pc, tv, and mini fridge. Now when they are running and the dehumidifier plugged in at other end of the basement kicks on, it throws. Also, I did add 2 recepts in my little office area, as the original ones were over 25ft apart (which doesn't sound legal even in the 60s).
I believe since all wire is 12 gauge I can replace the 15 with a 20 with no problems, is that correct? I just want to make sure I'm not overlooking something.
Also, before it's said - I know I should just add a new one, but the panel box is completely full. I already have everything tied up nicely and don't really don't want to get into replacing the box or adding one or even figuring out the wiring nightmare running into it just for this very small issue. If this doesn't solve the problem I'll suck it up and invest some time and money, but this house is temporary so I'm trying to half ass what I can.
