Being the stickler that I am (forgive me guys), I have to say it's pretty unlikely that even ancient insulation would fall off inside a wall cavity unless it was tampered with, and even if it did fall off, knob and tube wiring is separated from structural materials by insulating knobs and tubes, and from other wires by a couple of inches typically. Even if bare wire did rub up against wooden framing or plaster, those are also insulators, so I can't even imagine an arc occuring, not at a mere 120V anyway, unless a hot wire fell right up against neutral or a pipe somehow, maybe if a mouse sat on it or something, in which case a fuse of any rating would blow anyway.

Typical wall or ceiling thermal insulation of any type, fiberglass batts, foam, loose cellulose, etc, could be placed around any type of wiring safely because those materials are electrical insulators too. Best wishes, ~Eric

The old K&T wiring had insulation the would dry out and become very brittle, it would fall off due to vibration or touch. Blowing in insulation can cause it to fall off of large sections. If any moisture were to get into the wall cavity the wet insulation becomes conductive. As Kentvw points out, you are not permitted to insulate wall cavities with K&T wiring as per the NEC, period.

It was not meant as a derogatory remark (see the happy face) apparently you did not get the honor of being called less than bright, dumb, stupid, ignorant, etc and a few other choice names applied to Canuk, A.Spruce,Goldhiller, and myself by and infamous former member to remain unnamed. Relax JacktheShack, I like Canuk too even if he is from up there.:D

Congrats Canuk on 1000.

Around here, once you get around that millennial mark you can call each other all kinds of things because they've shared so many thoughts and ideas they're "friends", provided the poster isn't banned nor unregistered.

That's why I like these guys so much.

Just to clarify:
2008 National Electrical Code

Article 394 – Concealed Knob-and-Tube Wiring

394.12 Uses Not Permitted.

(5) Hollow spaces of walls, ceilings, and attics where such spaces are insulated by loose, rolled or foamed-in-place insulating material that envelops the conductors.

Thank you. I rest my case.:D

Yeah, that canuk fella don't know beans about the NEC. :D ;)

The electrical site I moderate you get more stars under your name as your post count goes up and five stars when you hit 1000.

Since I'm a moderator my stars are red......... So nanner, nanner, nanner! :D

No, but I have the power to cut ‘em down with a sickle or beat ‘em with a hammer!

Truth be known about the only “moderating” I do is make spell’n corrections……… Electricians are notoriously bad spellers as a group.

JacktheShack .... you humble me with your kind words ...... I tip my hat to you sir.:cool:

JLM's comment was in fun ... besides you just have to consider the source .... just like the other riff raff around here. :D :p :D

..... and Kent what do you mean I don't no nothin about the NEC .... here's a pic of the celebrations going on for the 1000th post party. You'll notice the approved flotation devices for the power bar.;) :D
