Hi I am about to build a deck ground level. I need to replace the original wiring that the previous owner totally hashed up. He used direct burial. As I a m putting a deck over whether the run needs to be. From the garage to the upper deck about 12" above the deck I am constructing. What is the best way to achieve this. I am Leary of direct burial in conduit.
Why? Cables are listed for running in a raceway, they are just hard to pull and usually require a bigger pipe than you would use for conductors. There is absolutely no extra (heat) derating in a raceway for a cable, no matter what the urban legends say.
If he doesn't like that, then use THWN wire in conduit, what's the problem?
