I have some 2" PVC conduit coming out of the ground and into a PVC box where it enters with a terminal adapter and held in place with a locknut. I intended to use a sealing locknut to keep the box watertight, but came across this discussion which has me worried the locknuts won't be allowed. Any advice? My AHJ uses the 2014 NEC.
Does that linked discussion apply to my situation? What is the correct/typical way to connect PVC conduit to a box outside (or are glued fittings generally always used)?
