I agree...K&T is grandfathered into the NEC, just like all the other improvements.
Could this be a new homeowners policy? Or is it just a renewal?

Insurance companies are not bound by NEC allowances and do can do as they please. At one time they were talking of requiring electrical updates every 25 years or cancellation of insurance.

I'm looking for an avatar of someone beating a dead horse if anyone knows where I can find one.

I know its legal but load protecting a grounding recepticle with a gfi makes no sense to me when there is no EGC. I don't see the need for it unless its in a kitchen, bathroom etc. Why not just replace one nongrounding device for another, not to mention gfi s are almost $15.

406 (D)(3)(a) non grounding type recepticles shall be permitted to be replaced with non grounding type recepticles

My 2¢

I have used GFI recepticals in knob and tube wiring to protect the homeowner. being no grounding conductor present it will pick up any imbalanced load or fault current and trip. I would use it at the first duplex with a result of protecting the wiring and people at all of the other outlets on the circuit. A GFI outlet does not use the ground to measure the fault current. It measures the current on the hot wire in comparision to the nuetral. If there is difference of more than 3 ma it trips. It was also a requirement for all old knob and tube wiring with the limits of Baltimore city Maryland. for 15 dollars you get a lot of protection.:)

I don't disagree with you. But nusance tripping can be harmfull as well. I don't think gfi protecting "all" outlets is a good idea. or afci for that matter. I think these practices should be more selective.

I respect your opinion. When I did that job there were not AFCI breakers. That would have been a better solution

That is a common practice in central Pa with insurance companies. And one I agree with. Way to many 4 mains and range boxes still around in these parts....

Nothing like doing a side job as a favor and when you show up the first thing you notice is the 60 amp meter base. And the favor is wiring for a 16000 BTU a.c.:mad:
