ABSTRACT:
A connector for connecting electrical conduit to nonmetallic electrical enclosures includes a connector body, a locking ring, and a conduit nut rotatably mounted on the connector body. The connector body has a first threaded end threadedly connected to the enclosure and a second end rotatably coupled to the conduit nut. The second end has an outwardly extending radial flange which mates with an inwardly extending radial flange on the conduit nut to rotatably couple the conduit nut to the body, without limiting rotational movement of the conduit nut on the body. The conduit nut has internal threads to mate with the male threads of an electrical conduit. The assembly allows an electrical conduit to be connected securely to the enclosure by tightening the conduit nut onto the conduit without transferring torsional stress to the non-metallic enclosure. The locking ring is threadedly coupled to the connector body and can be rotated to lock the conduit nut in place.
