Superior Electric YGA018 Locking Plug L5-20P 20 A 125 V AC Screw Terminals

Superior Electric YGA018 Locking Plug

The Superior Electric YGA018 is a NEMA L5-20P twist-lock plug rated for 20 amps at 125 volts AC. It is designed for electricians, maintenance crews and equipment operators who need a secure power connection on tools, machines or extension cords. The locking mechanism prevents accidental disconnection caused by vibration or sudden movement in industrial and commercial environments.

Replaces worn or damaged plugs on existing cords

This plug restores a safe, reliable connection when the original plug housing or blades are cracked, corroded or loose. The upgrade is worth it whenever a non-locking plug has failed because of incidental impact or cable strain. Galvanised steel internal posts with screw terminals make the repair straightforward and can be completed in a couple of minutes with basic hand tools.

Limited to 125 V AC single-phase circuits

The L5-20P configuration only suits 125 volt AC supplies up to 20 amps; it cannot be used on higher-voltage or three-phase services. The screw-terminal design accepts stranded or solid conductors sized for the circuit, but the plug itself provides no over-current protection. Installations must follow applicable electrical codes and the device rating must match the supply and load requirements.
