I have never seen this stuff before. Kitchen has been gutted. Most of the place has been rewired but there is still some knob and tube running into the kitchen from other areas of the home. I want to terminate those loose ends in JB's, device boxes, pot light boxes, etc. and cap them off.

What do I use as a "tube" to accomplish this?

Alternatively, I was thinking of just leaving them loose until rough-in inspection and asking the inspector what to do. It's not in my scope of work to trace those wires out and disconnect them but, if the inspector says it needs to be done, then I get my change order.

Leave them....wire nut the ends. That's a new can of worms

 

[Magnettica]

Yup, wire nut 'em or tape 'em!

If you can't 'harvest' some loom, use the sheathing of modern 12-2 (w/o the paper) , sleeve it over, and into two separate KO's in a non-mettallic box 99

They're live. They need to be brought into a box.

They are just as live outside the box also :laughing:

No splices ? I'd tape the ends and leave them. If there is no current running thru it, it's not going to do anything.

Actually, I'd tell them whatever I felt was necessary scare them into replacing all of the KT.

394.19 (B) Limited Conductor Space. Where space is too limited to provide these minimum clearances, such as at meters, panelboards, outlets, and switch points, the individual conductors shall be enclosed in flexible nonmetallic tubing, which shall be continuous in length between the last support and the enclosure or terminal point.

So I would say put it in 1/2" smurf tube from the last knob and then into a jbox, cap the ends.

I would cut it no further than 300mm from the last supporting insulator and tape the end of it and call it a day.

Why does it have to go into a junction box? there's no junction, no splice. Then if the inspector says do something else, you get change order, collect lots of money and do what the inspector wants.

K&T was "legally" spliced in mid air. So IMO it would not need a JB. Just cap it off. If you do put it in a box, do as was said and put it in separate bushed holes.
I just worked in a house about a month ago and the inspector allowed me to use clear tubing for a bushing. You can get it in a hardware store in several sizes.

I have used a product similar to this

You can't bring them into a light box, there is no temperature rating on the insulation. Cut it at the knob, leave an inch and tape the end.

That is what my inspectors say to do with it

I always thought stray ends of conductors had to be terminated in a box. I had an inspector tell me that so that's what I have always done. Anyway, I'll wait for inspection and see what he says. Thanks for the advice, guys .

I would cut it a little longer and loop the end. It's a little easier to tape it that way.
I think 300mm is a little extreme!

Yes for cables.. but probably no for open wiring. It's dangerous to bring them together. They're safer far apart and taped up on the ends.

Although, just do whatever your inspector says.. then it's on him.

 

[TOOL_5150]

They still make loom, knobs and tubes. If you have a KT wire that you want to abandon, cut it at the nearest knob and just tape it up. Forget all this other dumb stuff. We work with KT all the time in houses around here.

This is good info, ive never worked with it either but just had a job to replace a front porch light that was fed with it and re run romex from a new service. I plan to completely remove the hot but cant for the life of me figure out where the neutral was fed from. Ill just cut it and cap it off by the light.

Why not strip it and put a Wago on it?

Maybe he meant 30mm?

IMO, cutting it short near the knob and insulating the ends makes the most sense if you can't rewire the circuit and kill the old K&T circuit.

Collect the knobs and tubes for E bay, in there place goes NM-B.
