I have to extend a residential 12 volt camera power cable from the point where it pops out of the back stucco wall over to the center of the patio cover ceiling. It's only about 4 feet. I will use a box at the initial exit point and a 90 deg elbow and conduit over to a second box to mount the camera in its new location. The cable is regular old 22/4 comm cable. Here are my questions:
1 - I'd like to use emt instead of ent tubing but I would like to use non metallic boxes if possible. Since it's low voltage and only on the exterior meaning non of this conduit work will penetrate into the house is this ok to mix the metallic conduit with the plastic boxes?
2- If NOT ok in quesiton 1 and I have to use metal boxes with the metal tubing, is there any bonding needed of the emt? Note that the 12 volt circuit inside the conduit is not grounded.
Any help and code reference appreciated.
