Suggested Specifications for Non-Metallic
Sheathed Cable Fittings
• Where non-metallic sheathed cable or flexible cord terminates
into a threaded or threadless opening, terminating fittings used
shall be approved for the purpose by nationally recognized
laboratory, inspection agency or product evaluation organization.
• Terminating fittings shall be of malleable iron, steel or thermoplastic
construction designed to provide adequate strain relief and positively
prevent damage to jacket or conductor insulation such as series 3300
or 3302M manufactured by Thomas & Betts.
Ferrous metal fittings shall be electro zinc plated inside/outside
including threads and bushed with a nylon insulated throat.
Thermoplastic material used for connector construction shall be of
high impact strength suitable for 105° C/221° F service with a UL
flammability rating of 94V-1.
• Where non-metallic sheathed cable passes through either factory
or field punched, cut or drilled holes in metallic members, the cable
shall be protected by thermoplastic bushing such as series 3210
manufactured by Thomas & Betts. Bushing shall be firmly secured
in opening. Nylon bushed metallic fittings such as Thomas & Betts
series 1942 may be substituted as required.
