Red on terminal bar?

I've found range circuits using two paralleled 10-3 cables with no EGC.

Different code issues, I have found range outlets on 12-2 before.:blink:

Umm.....two sets of 10-3 is six wires not four. Also a range circuit would need the neutral.

sorry, forgot...

Maybe original was separate cooker/oven?

But two sets of 10-3 2s is four wires, so you put a green sheath on a white wire for ground..does not cover the wires in the walls but grounds the outlet and appliance..

Remember, the 3-wire major appliance rule was a case of the neutral being allowed to do the grounding, not the other way around.

Per 2017 250.119 Equipment grounding conductors shall be permitted to be bare, covered, or insulated.
Individually covered or insulated equipment grounding conductors shall have a continuous outer finish that is either green or green with one or more yellow stripes.

250.119(B) Where the conditions of maintenance and supervision ensure that only qualified persons service the installation, one or more insulated conductors in a multiconductor cable, at the time of installation, shall be permitted to be permanently identified as equipment grounding conductors at each end and at every point where the conductors are accessible by one of the following means:

1) Stripping the insulation from the entire exposed length.
2) Coloring the exposed insulation green.
3) Marking the exposed insulation with green tape or green adhesive labels. Identification shall encircle the conductor.

Per 2017 200.6(A) Insulated grounded conductor of 6 AWG or smaller shall be identified by one of the following means:
1) By a continuous white outer finish.
2) By a continuous gray outer finish.
3) By three continuous white stripes along its entire length on other than green insulation.
4) Wires that have their outer covering finished to show a white or gray color but have colored tracer threads on the braid identifying the source of manufacturer shall be considered as meeting the provisions of this section. The use of white tape, paint, or other methods of identification isn't permitted for grounded conductors 6 AWG or smaller.

Also note that BX cable is no longer recognized by the 2017 NEC Article 250.118 as a EGC. There is no internal bonding strip to ensure a path for fault current.

so, based upon last post, of the conductor is a grounding conductor then you can sleeve it or tape it with green or green and yellow tape and you are legal but if it is a neutral cable then you must pull and replace it... or did I read that wrong?

The term "BX" is not used, read 250.118(8).

Also there is nothing new in that section.
