Consider the following situation: A homeowner is remodeling his kitchen, and needs recessed lighting installed. The house was built in 1953, so none of the wiring is grounded. There is only one light fixture in the kitchen, and he would like that changed to a recessed can light, plus run 4 more cans off that, for a total of 5. What does the NEC require for grounding, since no EGC would be available at the original lighting outlet?
 
If the ceiling height is more than 8 feet, you might be able to use 250.110(1) as the basis of not installing an EGC. Otherwise, I think you need to add one. 250.130(C) gives you some options on how to connect an EGC when one does not yet exist.

I'd say250-120(c) then 250-130 (c).

Ok, thanks! According to that, I could just run a green wire from one of the new cans down to the panel, or to some other box in the house that's grounded.
 
Yea, and something about a single EGC run through the attic by itself never quite sat real well with me.
