Knob & Tube Help

I've got an old house build in 1888 that has a mixture of knob and tube and modern electrical. I'm removing an old light fixture in a bedroom that is live knob and tube. I have no plans to have a fixture here and want to be able to button up the knob and tube in some way that won't burn down my house, repair the plaster and get this project put to bed.

What are my options here?

First and foremost, electrical code requires every bedroom to have at least one switched light or lamp receptacle -- so make sure this change isn't violating that.

When removing any electrical wiring, it has to be completely disconnected from the power source and removed from the electrical box(es) that supply it before you can abandon the wiring and cover it. For K&T, this might require treking around the attic or basement to find those junctions.

Unfortunately, there is an outlet directly below the live wires from the fixture that is operational and in use so I can't just remove the whole line. Is it not kosher to simply wrap up or cap off these wires, place them inside the lathe box in there and plaster over?

No, you can never do that. They must remain assessable unless they can be properly abandoned on both ends. You can install a blank cover plate so long as you don't cover it up.

Even better use this as an opportunity to upgrade the wiring to the receptacle by running a new cable to the receptacle so you can abandon the K&T.

You probably have balloon framing which makes running new cables easier.
