I guess I did mean egc. I meant to put this in Contracting. Oh well...
Thanks for replies. If a #14 egc was run in a wall, would it pass as a means to ground a 15 amp K & T circuit?
Depending on the code cycle it was installed in - it could, what year was it installed? It also depends on where this 'EGC' goes???
Prior to 1999 I believe - and pretty darned sure - since I used to do it, it only had to go the nearest ground - which could have been a cold water pipe nearby... Or the panel the circuit came from...
In the '05 you would want to see 250.130 & 250.134, if on the 08 code it is the same with some very slight wording changes.
FYI for some time during the 60's ~ 70's gorunded outlets were required - but K&T was still being installed by some, and it was common to run a single EGC through the building to hit all of the circuits and tap from it within the walls to various locations.... These were usually bare copper and just stapled to framing, and soldered connections for the taps. If you have one of those - don't mess with it unless you plan to rewire the whole house....
But you usually only find it after some framer has cut it already....
