Correspondingly, can I use flexible conduit underground?
You can use a liquidtight flexible nonmetallic conduit for areas that are wet, damp, and where fire is most likely to develop. At the same time, a liquidtight flexible nonmetallic conduit can be buried underground, as corrosion is not an issue.
Similarly, what conduit can you bury? Bury in the Ground: Dig 24 inches. At 24 inches you can bury underground feeder cable, using PVC conduit to 18 in. below ground only where the wire comes up. If you‘re considering running a power line underground through your yard, you have four options.
Similarly, you may ask, how far can you run liquid tight conduit?

How deep do I need to bury electrical conduit?
