I will be installing a double oven that has an MC cable pigtail and needs to be direct connect. I am at the stage of drywall and cabinet install. Can I install a piece of PVC conduit behind the drywall that goes from the back of the double oven cabinet to the basement below? The goal is on the install to route the pigtail down the pvc conduit and do the direct connect in a junction box in the basement below. I think the length will be 2 - 3 feet.
