Would you feel better if I walked you through a dwelling with an IR cam., and found no worry spots?

How come we can't do it today? 95%+ of the service drops in my town are all SE, most of the guys here will tell you that's BS, and I have NEVER EVER seen it cause a problem:roll:
What do you we mean we can't do it today read article 394. Go ahead a wire a new house with K+T and see how far you get lol.

Work wih me chevy, not against me. I am not in the defense. Show your theory and close the discussion.
I have read 394 and tell ME if you or anyone can wire a new house in this day and age with K+T. Read it carefully and get back to me.

do you want to wire your house with knob and tube when romex makes life so much easier?


K&T can be less difficult than NM in many circumstances trouble wise. This is what I want to hear. Throw out some theory there chev. If K&T is so deadly, let's hear why????

I DON'T care about 394 chev, or your book. I am asking YOU chev, and you are bucking me. What is your validation behind this. Don't stand behind your book, throw me some THEORY.

Again, I am NOT in the defense:mad:

LOL, are you kidding anyone here? This whole site is based on the "NEC".
You want me to dispute the NEC, I'm supporting it. Maybe you should get on the same boat as you are on an NEC based site.
 
I love it. You can't throw me one SINGLE debate to back up your point. Not one single point. To heck with your books, show me some theory of your own. I have plenty of cold ones in the fridge, and I am waiting for you to stand up for yourself. Can't you do better than that "book" of yours?
 
Wire a new house with K&T. Why?

For starters, head down to your local supply house and ask for the knobs and tubes. That'll give them another war story to tell over the next, oh, say, 20 years. "Hey Fred. Did we ever tell you about the guy who came in and wanted to wire an house with knob and tube?!?!"

Second, you need special permission from the AHJ to do so. 392.10(2)

Third, do you honestly think any HO or GC with an IQ over 50 would even accept a new home wired that way?

Finally, who want to spend all that time? Drill a hole for each conductor... insert tube.... nail on all those knobs in the attics and wall cavities..... By the time you get done roughing one house, you're up to collect Social Security.

K&T was fine in it's day. 6 lights, 6 switches and 12 receps in a house was really a lot of electrical back then. Biggest power-hungry monster was the range, then the ol' Victrola.

And someday, future electricians are going to wonder why on earth we wired houses with NM......;)

I guess thats why you can do only your job and I can do mine. Not to waste your time but how about googling this topic and read some facts before you question me or this site.
 
knob and tube is a perfectly safe wiring method in my opinion. if i had the choice of installing knob and tube or romex id pick romex. easier to work with and faster to install. knob and tube is obsolete and thats why its not installed anymore.

And not allowed as a wiring method in new homes as per article 394. Good point.
 
I think you missed it Ken, no one said we would like to do a K&T new install. My point is what is so bad about the properly installed K&T from 50 years ago????. If it's been untouched, there isn't a harmful thing about it, besides no EGC, and even that isn't so harmful. The beloved NEC allows us to maintain it if it's GFCI protected.

Where does it say that?

Why can't you run another K&T conductor as a grounding conductor?

i think the reason why its not allowed is the magnetic field it creates in homes. having those conductors so far apart they wont cancel out eachothers magnetic fields. plus if you enter a metal box you need to cut slits in it to reduce the eddy currents. plus it could be a problem for people adding on to them. ive seen romex spliced without boxes to extend the circuits

Really?????? No deterioration of insulation what so ever??? How much have you dealt with K+T? Doesn't sound like much.
 
electricalperson said:
your allowed to extend knob and tube wiring just cant install it newwithout special permission. how many people actually asked inspectors to install knob and tube other than a 100 year old electrician?
Exactly my point. If it was so "safe" it would still be allowed as a new install but it's not.

ive seen insulation on conductors that were still pretty good. on the other hand ive seen insulation fall off just by looking at it funny. all depends on weather the circuit was overloaded, had insulation against it and other factors.
