| Application • To connect threaded metal conduit (ferrous rigid/non-ferrous rigid/ PVC coated/or intermediate metal) to a threadless opening in a box or enclosure in outdoors or indoor location exposed to continuous or intermittent moisture • To positively bond conduit to box or enclosure Features • Rugged steel/malleable iron/copper-free aluminum construction • Tapered internal threads for water-tight/dust-tight union (A) • Threads relieved to prevent bottoming of conduit, ensuring sound assembly (B) • Recessed sealing ring at box end; sealing ring captivated (C) • Hardened steel/malleable iron/copper-free aluminum locknuts designed to provide high-quality ground continuity; extended reach of locknut permits clamping on thin boxes and enclosures (D) • Insulated throat, insulates conductors, prevents abrasion and thinning of conductor insulation, reduces wire pull effort (E) • Suitable for hazardous location use per following: (i) Class I Division 2, Class II Division 1 & 2, Class III Division 1 & 2 per NEC 501-4 (b); 502-4 (a) and 503-3 (a) (ii) Class II Groups E, F, G, & Class III locations per CEC 18-202; 18-252; 18-302; 18-352 PVC coated 485 Series (i) Protects connector from extremely corrosive surroundings without affecting integrity of electrical grounding path (F) (ii) Provided with overlapping sleeve for additional seal (G) National Electrical Code® states that, "Where practical, dissimilar metals in contact anywhere in the system shall be avoided to eliminate the possibility of galvanic action."The only exceptions, aluminum fittings and enclosures, are permitted to be used with steel conduit. Joint Industrial Council (JIC) Electrical Standards also forbid dissimilar metals in contact for the same reason and require that the fittings for metal conduit be of malleable iron or ductile iron and have impact strength comparable to that of the conduit. |
