Knob and tube removal ??

[ritelec]

I'm pretty sure in the code that abandoned wires need to be tagged..
In the case of knob and tube, I have not had issues in the past of abandoning the existing wire in walls where to remove the wire would have been impracticable .

Is this still ok to do or has it become an issue and full removal of the knob and tube is required...........??

Could I label and tag the conductors, then bury them :- ) ??

thank you

I tape the end and shove it in the wall. Done.

So do I, but it was kinda brought up at ceu class and had me wondering if this technique has become a problem.

Removing K&T is not required even when it's accessible. Only chapter 8 wiring needs to be removed if abandoned.

Removing K&T is not required even when it's accessible. Only chapter 8 wiring needs to be removed if abandoned.

There is also a few Chapter 6 and 7 wiring methods that must be removed when abandoned.

 

[al hildenbrand]

And K&T is a Chapter 3 wiring method. The NEC is still silent about removal or tagging or otherwise identifying abandoned Chapter 3 wiring methods.

No reason to tag it or bury it. I often leave it for others to see and appreciate.

:huh:

In the past I have twisted all of the conductors together before burying so no one can mistakenly energize it.

You don't like to walk around an old building and check out the abandoned knob and tube?

Or if they do it'll trip the breaker/blow the fuse instead of hanging live inside a wall. good idea.

Old K&T is interesting, but I see overhead powerlines every day which arent a heck of a lot different.

And yeah, I guess some fiber optic or maybe cl2/3 wiring would need be removed if abandoned as well as perhaps 645 installs. afaik, all abandoned chapter 8 wiring is supposed to be removed.

That is my thought and it may keep Harry Homeowner from energizing some old nasty stuff that can burn the house down. If you tape it up it could be re-energized for decades (or less if it starts a fire) without someone knowing.

Not really, I see it constantly.

Why are wasting tape? I thought you Yanks were supposed to be thrifty.

 

[GoldDigger]

If you don't protect it from accidentally becoming energized you would have to ground it. :happyyes:

I use the cheap tape for that purpose. :lol:

Oh right, in that case I run a ground wire back to the panel.

Wires that are accessible in the course of maintaining live circuits must be tagged. Wires in trough, traveling through conduits, service gear, fire alarm, etc. This ruling does not apply to cables buried in walls or out of reach or necessarily visible or you would have to tag phone, cable, cat 6 and the like. Before you say "low voltage" there are pots and special phone circuits carrying 130v ac.

According to what code section?

Certain wiring must be tagged but typical premises wiring is not on that list.

X2-not required for chapter 3 methods typically seen in dwellings.

I would not worry about cut and capped K&T buried and pushed up in a wall with no slack left to easily connect it anything.

It can be offered or the customer can request that the old wire be banished entirely, but thats extra and their paying for it.
