New to the forum but really need some electrical advice. I’m in the process of taking down a knee wall in one of our bedrooms when I found an active knob and tube wire that runs right through it. It’s live, but I don't know if it’s the hot or neutral wire. I figured out which breaker it’s on, and it only powers a couple lights on the second floor that i can do without. So i know the breaker, but don’t know where the corresponding neutral wire is - There’s a couple of knob and tube neutral returns but i don't’ know which one’s associated with that breaker, and they’re backed in there pretty tightly. Most of the wiring has been redone but we still have a bit on the second floor. Question - with the main power off is it safe to permanently remove the hot wire from that breaker, and then proceed to cut the knob and tube wire that runs through the knee wall (which is either the hot or neutral associated with that breaker) and not bother trying to find and disconnect the neutral wire in the panel? I’ll likely have someone remove the remaining knob and tube wire from the house but the family is really strapped right now but hope to have it done within the year. Any advice would be much appreciated. Just looking for a safe Band-Aid solution to allow me to quickly deal either this one wire holding up my reno, and then I'll have a professional sort it once I've saved enough for them to remove it all from the second floor

Hello, My doorbell chime is always "on" I mean its plunger is up, and humming. The door bell button is disconnected, and I have replaced the transformer. I need to identify the wires and start over. The transformer had two red and two blk on the 2 terminals. the chime had two blacks 1 "front" 1 "back" and two reds to "trans" this made the chime always "on" any ideas??
