approved by a nationally recognized testing laboratory, inspection agency or product evaluation organization.
2. Where corrugated-jacketed metal-clad cable exposed to intermittent or continuous moisture is terminated
into a threaded opening, the fitting shall be watertight type furnished with:
a. An elastomeric beveled bushing.
b. A funnel entry, splined gland nut.
c. A non-magnetic stainless steel grounding device with dual grounding action.
d. A taper threaded hub.
e. A hexagonal body and gland nut as manufactured by Thomas & Betts (aluminum series ST050-464).
3. Where cable is terminated into a threadless opening, a suitable moisture-resistant elastomeric gasket as manufactured
by Thomas & Betts, series 5262, shall be provided between the outside of enclosure and fitting shoulder.
4. With single conductor cable and/or in corrosive environments, aluminum fittings such as Thomas & Betts series ST050-464
shall be installed.
Class I Div 2; Class II Div. 2; Class III. Where explosion-proof or dust-ignition-proof boxes are required by Teck, fitting must
be used in conjunction with an approved sealing fitting.
