Watertight Locking Plug L6-20P

This industrial-grade plug provides a secure 20 A, 250 V AC connection for equipment requiring a NEMA L6-20P configuration. Its thermoplastic elastomer housing resists chemicals and impact while maintaining a watertight seal. The yellow housing ensures high visibility in demanding environments. It is built for straight-orientation wiring with screw terminals.

Three-pole two-phase straight connection

The plug accepts cable diameters from 0.375 in to 0.875 in, accommodating a range of industrial cord sizes. Screw terminals allow reliable field termination without specialised crimping tools. Polarised blades prevent misinsertion into incompatible receptacles. The watertight design protects the connection in wash-down or outdoor locations.

20 A 250 V AC capacity headroom

This device comfortably handles single-phase loads up to its 20 A rating at 250 V AC. It is not suited for circuits requiring higher amperage or three-phase power distribution. Builders needing a different NEMA configuration or a higher current rating must select an alternative plug. The screw-terminal wiring style supports standard industrial installation practices.

Questions about this item

What is the maximum continuous current the L6-20P plug can handle before the 20 A rating becomes the limiting factor?

The plug is rated for 20 A at 250V AC, so the 20 A current rating is the primary limit under sustained use.

How does the thermoplastic elastomer housing perform regarding heat buildup during all-day operation at full load?

The industrial-grade housing is impact and chemical resistant, designed to withstand heat generated during continuous 20 A operation.

What cable diameter range must the installer already have on site to fit the screw terminals?

The plug accepts cables from .375 in to .875 in diameter, so the supply cable must fall within that range.
