NCG, NCGB and NCGS Non-metallic Portable Cord Connectors

For use with portable cord, Crouse-Hinds series NCG and NCGB watertight cord grips terminate and protect conductors from mechanical damage due to vibration and movement.  A neoprene bushing seals out oils, coolants, water, dust and other abusive agents.  NCG and NCGB cord grips may be used with types S, SO, STO, SJ, SJT, SJTO and SVO portable cords.

NCGS non-metallic cord grips are used in both commercial and residential grid-tied PV solar applications and are designed to accommodate the entry of multiple PV wires coming into a combiner or pass through box.  NCGS cord grips also provide mechanical strain relief as well as a liquidtight seal around the solar panel wires.
