What do you use to support conduit when is suspended in a ceiling?
To support conduit that is suspended in a ceiling, you typically use conduit hangers or straps. These devices secure the conduit to the structural elements of the ceiling, such as beams or joists, ensuring stability and compliance with electrical codes. Additionally, you may use threaded rods or wire for added support, especially over longer spans. Proper spacing between supports is also essential for maintaining the integrity of the installation.

PVC is cheaper but is used differently. PVC is usually baried in ground and emt usually runs exposed. You can use PVC exposed if it is schedule 80 gray PVC electrical conduit. Schedule 40 is for under ground
