I ripped down the basement sheetrock ceiling in my 1926 house to take a good look at the wiring and also so I can continue with my generator connection project.
I'm seeing something that I am not completely comfortable with and I wanted to get some feedback on if this is OK or not.
My house still has some knob tube hanging around. I've undertaken the project of removing all this old stuff. I can see that my house is a museum of electrical cabling over the century. I have some K/T, I have some, old AC, some newer AC, some older romex, and some newer romex, Heck, I even discovered some gas lighting
So first off, i found buried junction boxes. I know this is a no go. But my main concern here is that a single 14/3 is run into this box. This 14/3 goes to the circuit breaker panel. They took the red hot wire and put that into one 20 amp breaker, then they took the black hot and put that into a different 20 amp breaker. back in the junction box, they shared the neutral between 2 totally different circuits that splice into K/T in the junction box.
This just doesn't seem right to me. Am i wrong in thinking that this is just plain wrong and they are actually sending 40 amps back over the neutral at full load? Also, i dont think K/T is 12 gauge wire, probably more like 14. Wouldn't i want to give each their own 14/2 on separate 15 amp breakers?
Thanks for the input.
