Of course you can wire nut K&T and Romex, in any approved J-box.

wrong and so funny you are!

Brad says he is in Cleveland Ohio. Guess some of you don't know that Cleveland didn't allow Romex and required K&T even new construction to the early 70s. Mom still has the family home she and Dad purchased new in 1972 -- all K&T romex wasn't allowed in Cleveland.

Cleveland has SPECIAL RULES (ordinances are law) they are very strict about what is and is not allowed and what is and is not maintenance when it comes to K&T. Brad needs a permit. Brad isn't allowed to replace K&T from the switch box to two fixtures with Romex and leave the rest of the circuit K&T, that's Cleveland rules.

Home insurance underwriters know all about which homes have K&T and which don't especially around Cleveland. Get caught on an inspection or a claims adjuster sees unpermitted work on the original K&T and kiss that insurance claim check goodbye or expect it to be greatly reduced, and your homeowner's insurance dropped.

You can call Mr. Cooper at the Building department at 664-2386, or one of the inspectors and they'll explain 3137 to you. Ask about the difference between 3137.05(e) and (f) and that neither allow you to replace permanent wiring. Since you're not using K&T methods to replace the original ask him to explain about 3137.2(c)(15) so when you pull your legally required permit and get it inspected you won't get tagged out and have to redo all your work.

Re: Knob & Tube meets NM

One thing to be careful with K&T is that a lot of it is old and the rubber insulation under the cotton braid is brittle. Any time you disturb it -- and this can be as inoccuous as bumping the wire when you're rustling in the attic -- it's a really good idea to inspect it to make sure you didn't knock the insulation off or split it. If that's the case, you'll need to very carefully tape it up or replace it.

I agree. K&T is very delicate stuff. Very sound advice.:D

That is hard to believe Knob and tube was allowed and to be installed up to the 70's. With all the hazzards with knob and tube. maybe conduit I would believe that.

I agree but I just leave those things pass.:D
I just might "google" Romex to find an introduction date.
