Question I notice my panel has 5 30 amp breakers. I am wondering what those could be used for. We have only one 220v outlet, and maybe 220 for the AC. I believe the furnace is 120v. Almost all the wiring in the house is 12ga, except maybe a few places with 14ga. I will check tomorrow, but I'm worried that it is going to outlets.
It probably won't help, but I included a link to a picture of the panel. It has never really been labeled, and I see someone has written "new AC" with arrows point to two 20A breakers (not double-pole). Clicking on the picture will show a larger version, then clicking "view raw image" will show the largest view of the image.
If you feel comfortable opening the panel, you can check the wire size coming from the breakers. If the wire size is #12, the maximum breaker size is 20amp. If a circuit has #14 wire in it, the maximum breaker size is 15amp. You should also purchase a breaker closure plate for the spaces that are covered with tape.
The breaker feeding the a/c unit, if ithe unit is 240v, should have handle ties tieing the two breakers together, or replace it with a 2-pole breaker. Check the a/c unit's nameplate for the maximum breaker size required to feed the unit.
