For applications where termination into a threadless opening is required, an acceptable sealing ring shall be used. In all cases,
15、the conduit termination shall provide a water-tight fitting at the interface. 3.1.3 Conduit system. Conduits, conduit fittings, and constituent parts shall provide for installation, removal, inspection, and reinstallation of assemblies between fixed threaded fittings. The conduit system shall have a
16、t least one swivel fitting attached or other means of securing the conduit to the fitting without causing or requiring the conduit to rotate during the fabrication. The conduit system shall provide protection for the conductors and cables contained therein. Provided by IHSNot for ResaleNo reproducti
