Will,
Very handy information to pass on…thats what this thread was all about…to me it was getting involvement and bringing things out and learning from it…nothing more.
I don’t care to know it all…but what I do know I want you to know…at little bits at a time…thats why I am here…
Todd…actually " Service Conductor" never comes into play here on this example…but I think you really wanted to say " Ungrounded" conductor…
Yes Todd…but should only be done by a licensed electrician…because while 250.130© permits this application…it is important to know a few other things as well about that article…
One thing is and you guys will see it ALOT…someone has a normal 2 wire NM Cable running into the attic…with no EGC…and they tap onto it with a new lets say 14-2 W/G and then run it to another location and put it in a box…and then since at that point it has 2 conductors and 1 bare EGC…they think they can at this point use a 3 hole plug…well…NOT…
So as you can see…under the watchful eye of an electrician the homeowner has a few addititional options to play with…
Hope this helps explain the clients options so they dont go into cardiac arrest when they find out they dont have grounded plugs…
Ironically…many will argue a 2 wire system is technically grounded because of the neutral…but it is not providing a EGC…so really we are adding for the EGC to the system.
