I have 2 6/2 with ground cables installed in my attic. I got a oven that requires a 4 wire (2 hots, 1 neutral, 1 ground). Is it code to utilize the 2 insulated conductors off of 1 nm cable and 1 - off of the other as my neutral?
I would install on neutral bar in panel, make the final splice in a jbox then just extend the correct 4 wire to the oven connection. I do not think it is code but cannot find the scenario in which it rejects that. I do not have access to get to the panel from the oven and want to utilize the existing wiring i have i place if possible. I know it would work, but is it code, and what are the dangers?
