I am installing a 2 inch SCH 80 PVC conduit for a 15 feet run on a brick veneer wall. The conduit exits main service panel at a knockout 45 inches from the ground, travels 11 feet horizontally, takes a 90 degree turn, runs for another 2 feet before terminating into a L-conduit-body. The other end of the conduit body enters the crawl space through a hole in the brick wall.
What is the best way to support this conduit on the wall? Can I use metal strap hangers like these? My inspector has cleared me for using these, but wanted to check what you guys use for conduit that big.
Second, does NEC allow one conduit to go over another? The conduit in question will intersect a 1/2 inch EMT conduit run at a single point. The metal straps I linked above raise the conduit enough from the wall to create the needed clearance.
