Where in the NEC does it require nonmetallic pipe to be glued? If so, is a primer required?

110-3(b) because it is in the UL listing. The white book says: "PVC conduit is designed to be connected to couplings, fittings, and boxes by the use of a suitable solvent type cement. Instructions supplied by the solvent type cement manufacturer describe the method of assembly and are to be followed." I have never seen instructions of electrical grade solvent type cement requiring the use of a primer. Also 347-6 requires the use of an "approved" method.

Don has nailed this answer 100%.

I have used the primer on ocaision. The reason I've used it is because some fittings are fairly loose when installed on conduit of a different manufacturer. Priming the conduit & fitting makes a better bond between the two.


Few things are harder to put up with than the annoyance of a good example.
