Old Oven Circuit

[Will Wire]

I have a customer who's oven circuit shorted in the junction box under the oven's cabinet compartment. It is a three wire circuit with a insulated grounded conductor. I know that the code allows for grounding the frame and associated j-box with this conductor in existing installations only. Because of the short, a hot conductor in the j-box is hardly long enough for a good connection. Also the flex off the oven barely reaches the j-box. Will I be violating any code reguirements if I move the j-box closer to the panel to lengthen the damaged conductor and then splice at this j-box and run conductors in flex to another j-box behind the oven that the oven flex will reach?

So long as the new/added j-box is accessable, you should be fine.

Can you not replace the entire run? Some inspectors may have issue with this install, however, IMO it is existing and should be allowed. I would replace the cable if possible.

I've never seen a 3 wire circuit with an insulated grounded conductor unless it also has a bare ground along with it...but then it wouldn't be a 3 wire circuit it would be 4. So I'm curious...what kind of cable assembly is this. Give me all the details. Manufacturer, wire size, romex or se, yada, yada, yada...

Garth-- they use to make 8/3 NM without a ground

so it had just a black,red, and white with no ground?

Ungrounded cable has been on the scene longer than nm cable with a ground. And yes in the three wire cables are red, white and black.
