Re: Oven wiring - help please A picture would be most helpful in confirming what type of cable was used to run the existing circuit. From the description (B-W-bare) it's two-conductor with ground NM (Romex). It was never code-compliant to use the bare equipment grounding conductor in NM (Romex) to feed dryers/ranges where the frame is bonded to the neutral. The only cable with an uninsulated neutral permitted for 3-wire range and dryer circuits was type SE. Since the original circuit was never code-compliant and "grandfathering" doesn't apply, it must be replaced with a properly sized 4-wire circuit.
Yes, the oven can be connected to the existing circuit but doing so is a code violation and potential hazard so I'll leave the how-to for someone else to explain.

Unless the previous range operated at 240v only and did not require a neutral. If it had a timer, clock, or an outlet that's probably not the case though.
Without at least pictures in this case, saying what is or isn't code or grandfathered is just guessing. |
