This industrial-grade Twist-Lock® flush receptacle provides a locking connection for 30 A, 125/250 V power installations in indoor dry environments. Recessed wire restraints help reduce terminal loosening during back or side wiring, while the all-brass mounting and grounding system offers corrosion resistance and a low-resistance ground path. Voltage colour coding helps crews identify and mate the correct devices during installation and maintenance.
