Industrial 20 A L6-20R Twist-Lock Connector

The Hubbell HBL2323 is a 20 A, 250 V AC locking connector built for industrial and commercial power distribution. Its L6-20R NEMA configuration provides a secure, grounded connection that resists accidental disconnection. The Insulgrip nylon housing and brass contacts deliver durability in demanding environments. It accepts 16 AWG to 8 AWG conductors via screw terminals.

Replaces worn or non-locking 20 A plugs in dry

This connector upgrades installations that currently use straight-blade or damaged twist-lock bodies where vibration or movement causes intermittent contact. The jump is worth it when equipment must stay powered in areas with mechanical stress, such as machinery, temporary power panels or stage lighting rigs. IP20 rating limits use to dry, indoor settings only.

Sustains 20 A continuous load within -40 °C to +75

The nylon housing meets UL 94 HB flammability standards and maintains mechanical integrity across the full rated temperature span. Brass contacts resist heat rise during prolonged operation, while the cord grip prevents strain on screw terminals. CSA C22.2 No.42, UL 498 and Federal Spec W-C-596 compliance confirm performance under continuous duty cycles.

Questions about this item

What wire gauges can the HBL2323 screw terminals accept?

The connector accepts wire sizes from 16 AWG to 8 AWG using its screw terminals, suitable for 20 A circuits.

How do you correctly assemble the Insulgrip twist-lock body onto a cord?

Strip conductors to the gauge strip length, insert fully into the brass screw terminals, tighten screws to spec, then seat the cord grip over the jacket before snapping the nylon housing shut.

When should the L6-20R connector body be replaced in service?

Replace it if the nylon housing shows heat discoloration, the brass contacts are pitted, the twist-lock cam no longer engages securely, or the cord grip fails to hold the cable jacket.
