I assume it is length limit from the GFCI breaker and not the receptacle GFCI, correct?

What is the length limit?

ETA, you know, I vaguely remember I read something on this year's ago. I will check in the UL book and see if it was there.

It is the length from the gfci, it is around 100 feet so rarely seen with a receptacle device.

I should have asked what kind of "protection" you're seeking.

An EGC assures that a L-G fault makes the OCPD behave like it would for a L-N fault.

This questioned was asked and not answered. My first thought was this. It really is the crux of the post.
 
I prefer getting a ground cable and rod in , I know there will be work and cost - "the ground makes it sound" My experiences with this have not been the best . there is comfort in being well grounded.

You mean installing a grounding rod and connecting the receptacle to it via an EGC?
 
I have learned from past experiences not to touch older home wiring that have cloth wiring. Any movement of the wiring will usually cause damage to the wiring insulation. Then it becomes a "Pottery Shop" issue.
 
These are pictures from an inspiration I did on an older home with cloth covered wiring. The contractor abandoned the wiring upgrade project.

Here we can't use that 406.4 (D)(2) b or c for appliances, motors and equipment covered under 250.114.
Such as Motors (ceiling and bath fans), refrigerators, freezers, air conditioners, dishwashers, disposals, computers, sump pumps, dryers, ranges, aquarium equipment etc.
In those cases we install a new circuit or an EGC as per 250.130(C).

It's not that bad. It's kinda in boxes, they used wire nuts, and I don't see any lamp cord

In my experience, the damage is done long before anybody touches it. The 80-plus year old natural-rubber insulation has hardened and turned to dust, but remains moderately effective so long as the cloth jacket retaining it isn't disturbed.

If you tape it up before doing anything else and it hasn't been exposed to high heat you can keep its integrity fairly well. The first jobs I did as an apprentice were durring the recession and they had no warranty issues because of degraded insulation.
 
I forget I have a camera. I got a call wants me to finish a service that had been rejected. 200 panel below the meter socket. They had stripped a piece of 6/3 to use the wire, black one to one leg, while to the other and red for the N and somehow managed to fit a piece of innertube in the hub. I was busy, the county has their own inspection, this would have been a revisit under the homebrew permit,,, I just said wow.
