Hubbell HBL8319CT 20 A Straight Blade Connector

The Hubbell HBL8319CT is a hospital-grade straight blade connector rated for 20 A at 125 V AC. It uses a NEMA 5-20R configuration with two poles and three wires. The Insulgrip housing is transparent and accepts cable diameters from 0.23 in to 0.72 in. Screw terminals provide the wire connection.

NEMA 5-20R Configuration and 20 A Rating

The single specification that decides fit is the NEMA 5-20R configuration combined with a 20 A current rating. This connector matches receptacles and plugs built to that exact standard. It is single-phase, grounded, and rated for 1 hp motor loads. Dust-ignition-proof, moisture-resistant, and weather-resistant properties suit demanding environments.

Suited for Hospital-Grade 20 A Circuits

This connector suits electricians and facility managers wiring or repairing hospital-grade 20 A 125 V AC circuits. It is not for buyers who need a different NEMA configuration, a higher amperage rating, or a connector with an integrated cap or cover. It also does not suit low-voltage or data applications.
