Does 8 3 Wire Thru The Attic Need A Conduit. I have always been led to believe that single strand wire needs to be run in conduit and may not be run inside the walls of a home or building. Of wire they support. Use a splice box when installing.
A 1 2 inch conduit can hold as many as nine 12 gauge wires or twelve 14 gauge wires. This will protect your wiring from damage by exposure or rodents.
I m building a new home outside the city limits in liberty county in texas my electrician ran the main power feed wire from the meter through the exterior wall up into the attic and down into the breaker panel without any conduit.
I am adding a sub panel in my attached garage and was going to run 6 3 romex from the outside main panel in the crawlspace underneath the house up through the floors into the garage. The national electrical code has specific regulations for how many conductor wires can fit into within a conduit of each diameter size. The clips allow easy access if you need to run more wires and cost 40 for every 8 ft. Conduit is durable and strong and can last a long time.
