Yes, that represents a junction box. There was originally an outlet there. Yes, these are all the wires leaving this box. The panel says Sylvania. Im not sure on the breakers. I took some pictures if it helps. The breakers in question are the first 2 full size breakers. It looks like I have several of these multi wire circuits. Would I find the make of the breakers if I removed them?
On that note, should I remove the #9 breaker and see if there is still current there?
