I'm asking about my parents brick single family home that we are the original owners from around the late 50s. We were planning to sell the house and had the village come in to see what might need to be "updated" or corrected before selling. On the list was to label all breakers in the panel, as some were not labeled. It is the old Pushmatic panel which is said to cause fires and needs to be changed but he said it looked good, so no need now, so on to the question.
I found one 15A breaker was supplying power (lights & outlets) to the Master bedroom, 2nd bedroom, hall light, all 3 bathrooms, basement main lights and a front outside outlet. I had the panel cover off and there was only one 12ga wire going to that breaker which means it is split off to all the other rooms somewhere upstairs in the house. I have no plans on doing anything about it now or before we sell as we never had an issue with the breaker popping in the 50 years we have been there.
The question is, now that everything is labeled, there are 8 stickers next to that one breaker, not sure how much the Buyer's home inspector is going to want a discount on the selling price to have to run home runs for the extra rooms and most likely have to swap out to a new breaker box with more slots, since there are only 8 breakers to use besides the A/C and Dryer double pole ones.
