Review on 🔌 Industrial Grade Leviton 2620 Locking Receptacle, Flush Mount, Grounding, 30 Amp, 250 Volt, V-0-MAX, Black by Dee Rawls

Good twist lock 30 amp socket. You push, insert and twist this socket, which locks it in place. This ensures that whatever device you have plugged in stays securely connected to the outlet. The wire enters from behind and the rotation of the screw pushes the moving plate against the wire. You don't wrap the wire around the screw, you simply cut the wire to the right length to go behind the plate and tighten the screw that holds it in place. This plug is used in the garage to power a high load device. Make sure which plug you need before purchasing as there are many options. You will most likely want to use a deep box or extended rosette with this connector to allow room for the stiffness of the thick wire you will be using to make room in the box.
