As I understand it, you could do that for a two wire 120V receptacle, but not for a high current 240V range receptacle.

I don't see any language in 250.130(C) that restricts it to 120V receptacles.

But 240 is much more likely to be more than two poles in the first place.
It does not say you can do this for any ungrounded receptacle can be treated this way, only a two wire.
JMO, not having looked at the exact wording today.

250.130 (2011) doesn't use the word "two", as in two-wire. Is there a different section that refers to that? The last sentence of 250.130 says "For replacement of non–grounding-type receptacles with grounding-type receptacles and for branch circuit extensions only in existing installations that do not have an equipment grounding conductor in the branch circuit, connections shall be permitted as indicated in 250.130(C).
Cheers, Wayne
I concur because 250.130(c) is referencing non-grounding type receptacles and circuits w/ no egc, and those 3wire range circuits and old NEMA 10-30 and 10-50 tombstones were just that.

Glad you agree. One thing I'm having trouble with. You list your location as Texas. I'm a Coloradan. Please tell me you moved there from somewhere else.

Nope-I'm a native-there, I said it.

I moved to Texas from Louisiana, but I moved to Austin, which isn't a whole lot like the rest of Texas.Glad you agree. One thing I'm having trouble with. You list your location as Texas. I'm a Coloradan. Please tell me you moved there from somewhere else.

You can't run it on the outside of conduit.

No. 250.102 is the only place where it is allowed. That section deals with bonding jumpers and restricts the length to six feet, except for grounding electrode connections.

One more time, that is only acceptable for existing installations.
From the sounds of it this homeowner ran the circuit without an EGC and then added one to the outside.
That is not existing, that is new work and is an NEC violation.
