Grounding Bushings are intended for use with threaded rigid or intermediate metal conduit and an aluminum or copper lug for connecting a bonding or grounding wire. Never exceed or reduce the wire capacity specified on the lug or carton label. Bushings have insulated throat for abrasion protection when pulling wire, black or brown colored insulator rated for 150 degrees C, other colors rated 105 degrees C. The set screw in the Bushing assures bonding to the conduit.

When installing a Grounding Bushing to rigid or intermediate metal conduit, a locknut must be used on the inside and outside of box or enclosure. Assemble the Bushing hand tight and with wrench, or similar tool, tighten additional 1/4 turn; tighten set screw and assemble bonding or grounding wire. Note: the Bushing lug may be rotated to prevent interference with box or enclosure. Tighten screw securely after repositioning lug.

Grounding Bushings provide electrical continuity required by the NEC for service entrance and circuits rated over 250 volts.

Always use UL listed Grounding Bushings, Bridgeport die cast zinc cat. nos. 381-DC through 389-DC40 or malleable iron cat. nos.381 through 392
