The same generation of wire also produced 10/3 nm without ground. I have also seen and used 8/3 without ground that had a plastic jacket not cloth. I may even still have some in the basement. :smile:

You must be old. lol I use to sell it in my days in the supply business.

That generation must still be around. Every new house I do has some 12/2 w/o ground in it.

Yep for central vac systems.... 14/2 also. You don't see electrical suppliers stocking that stuff. 10/3 and 8/3 w/o ground is not stocked anymore.

And I am not old just seasoned. Hitting 58 in Feb. I expect lots of presents at my door....:smile:

Absotively posilutely! And of course, they can never stuff it in a general-purpose circuit with both a hot and neutral. They gotta stick it into a dedicated circuit (SABC, laundry, etc) or a dead-end 3-way.

When I read the OP question I thought he was refering to the ground. I didn't think it was o.k. not to have it in 2002 but I can't remember. How many places are 6 years behind on code updates?

The op never clarified if he meant 6/3 with ground or without. I think that is what he meant but am not certain. He may have been referring to the use of nm instead of se cable.

Isn't odd, how we most often say X/2 or X/3 and assume the ground, like with NM or MC, but we know to add a conductor with cables like SO or SJ?

That's probably more true for the younger guys who didn't spend years working on ungrounded wiring. Someday when a residential electrician talks about a breaker it will mean a GFI/AFCI type because that all he's ever seen.

Me too, about a month ago.

I called a hardware on a remote job (out in the sticks) and asked if they had any 6/3 Romex....they said yes.....I said cut me 40 feet and I'll be by in a few minutes to pick it up.

Without paying attention, I bought the wire and snaked it under a house.
When i got ready to make up the receptacle, I stripped off the outer covering and guess what....No grounding conductor.

Needless to say, I was PO'd, at myself and the guy who sold it to me.
I took it out and took it back. Sadly, it was the only 6/3 that they had.
They did refund my money after I got pretty upset and ranted about there being no legal use for 6/3NMB without a grounding conductor.
There may be, but nothing came to mind at the time.:-?
I had to drive 25 miles to get the correct wire.

A little lack of attention cost me about 4 hours.

Hmmm, 2002 NEC wiring with romex, not sure why were asking about an EGC in the cable. IMO the question is based on the ampacity of NM. If the original poster comes back we might find out what his real question is. :wink:

The real question: How does an Electrical Engineer that designs aircraft electrical power systems install a 50A circuit for a new electric range? :grin:
 
I know its an old post but I'm cleaning up my email. Correct me if I'm wrong, and I'm sure someone will, but it is perfectly legal to make up range cords (not branch circuits) with 6-3 to match existing 3 wire range circuits.

Correct. In an existing installation, the branch-circuit wiring determines everything else: the receptacle and the cordset. And, one must be diligent about connecting or removing the appliance's bonding jumper as necessary (after finding it.)

I was asked to reconnect an older 3-wire dryer for the new 4-wire circuit. I found the bond between the white and green wires in a wiring harness deep inside the dryer. I showed the customer why I had to charge extra; no arguments.

Ranges run on 400 Hz, don't they? :cool:

(Of course, the clock isn't accurate.)
