If either of these breakers are on, both of these wires have power. I believe that makes this a multi-wire branch circuit and that, configured thusly, this is a multifeed and that that is dangerous. Is that right?
I bought this house three years ago and am trying to untangle some electrical problems that came with it. Learning as I go. I did not wire this panel -- I bought it this way.
Using my voltage detector pen, I can determine that if either of these breakers is on, both of these wires have power. Also, I traced the wires up to where they exit the box in a cable, and although it's hard to see so I can't be 100% sure, I'm 99% sure that they are part of the same 3-wire cable. Using the pen again, if either of these breakers is on, the cable registers voltage.
My research suggests that this is a multi-wire branch circuit and would be OK except that the two breakers should be on different buses, which these are not. I'm just hoping to confirm that understanding so I can see about fixing it.
Thank you for any insights!
