TWIST-LOCK® plugs and locking receptacles:

15A, 20A, 30A
2-Pole, 3-Wire
3-Pole, 4-Wire
4-Pole, 5-Wire

On the high impact nylon face of each Hubbell TWIST-LOCK® receptacle is a ring of color. Keyed to an internationally recognized color coded scheme, this ring enables devices with identical voltage rating to be matched quickly. The terminals in each Hubbell TWIST-LOCK® receptacle are mechanically and electrically the finest available. These terminals incorporate unique design features to contain and hold conductors, including an external back wiring wraparound clamp, a wire restraint recess and more. The all brass mounting system provides a safer, low resistance ground path than those made of steel. The thick wall base is constructed of an engineered thermoplastic to offer the benefits of a thermoset, yet with much greater impact resistance. Long after most conventional TWIST-LOCK® receptacles have weakened and allowed the cord to slip. The Hubbell INSULGRIP® retains its strength INSULGRIP® features an offset cord gripping design that actually clamps the conductors, not just the cord jacket. The nylon body and housing are resistant to industrial chemicals, solvents and hydrocarbons. The front of each plug is molded to its specific blade configuration. Leaving no holes to invite debris or contamination.
