Watertight L14-20P locking plug

This straight-orientation plug carries a 20 A rating at 125/250 V AC and uses a NEMA L14-20P configuration with four blades and three poles. The housing is moulded from black and white polybutylene terephthalate that resists chemicals and impact. Screw terminals accept standard wiring for single-phase polarised connections.

Builders who need a weather-sealed 20 A connection

The watertight seal suits outdoor or wash-down environments where moisture and debris would defeat a standard inlet. Installations that require a different NEMA layout, a higher amperage rating, or a non-locking straight blade will need a different device.

Sustained 20 A load in wet conditions

The chemical-resistant and impact-resistant housing maintains its seal while the screw terminals hold conductors securely during continuous single-phase operation. The 1.15 in maximum cable diameter and 2.77 in face diameter allow a firm gland fit that does not loosen under vibration or thermal cycling.

Questions about this item

What NEMA receptacle must I already have for this L14-20P plug to connect?

You need a matching L14-20R receptacle rated for 20 A at 125/250 V AC to accept this straight-orientation locking plug.

Will this watertight plug fit the same 1.15 in maximum cable diameter as my older L14-20 devices?

Yes, the housing accepts cables up to 1.15 in diameter, so existing cords within that size will terminate correctly.

How can I verify the screw-terminal wiring is correct after assembly?

Confirm each of the four blades seats firmly in the L14-20R receptacle and that the 20 A, 125/250 V AC circuit powers the connected load without tripping.
