I'm replacing a range hood with an above range microwave. I discovered that the range hood was on a dedicated circuit so will use that to power the microwave. I have a grey plastic surface mounted box with the 1/2" round knock outs for a NM clamp. I plan on mounting the box inside the cabinet and attach it to the back of the cabinet (screw into the wall stud behind). The plan is to make a hole in the back of the cabinet to fish the nomax wire through and into the back of the box using a metal NM clamp to secure the wire to the box. Is this acceptable? No need to ground the metal clamp as one would need to do to a metal box?
Thank you.
Thank you.
