Hospital-Grade 5-20R Receptacle

This Hubbell HBL8310GY is a single, flush-mount outlet rated 20 A at 125 V AC. It carries hospital-grade certification and a four-point grounding system with a nickel-plated brass integral ground strap. The impact-resistant nylon and reinforced thermoplastic housing suits demanding healthcare environments.

Suited for clinical and heavy-duty use

Installers needing a rugged, code-compliant receptacle for patient-care areas will find the back-and-side screw terminals and #12-#10 AWG copper-wire capacity appropriate. It is not intended for buyers who require a different NEMA configuration, a higher amperage rating, or a device without hospital-grade listing.

NEMA 5-20R configuration decides fit

The receptacle accepts only NEMA 5-20P plugs, so the branch circuit and connected equipment must match this 20 A 125 V standard. Verify the plug type and local code requirements before specifying this part.

Questions about this item

How much heat does the receptacle generate during continuous 20 A operation?

The device is rated for an operating temperature range of -40°C to +75°C without impact, and its nylon reinforced thermoplastic polyester housing is designed to handle the thermal load of a 20 A 125 V circuit.

What wiring and mounting items are needed before installing this receptacle?

You must supply #12–#10 AWG copper wire for the back or side screw terminals, a compatible flush-mount box, and basic hand tools; the receptacle includes its own mounting hardware.

Will the nickel-plated bypass contacts maintain reliable contact with older #12 AWG copper wiring already in the wall?

Yes, the nickel-plated brass integral ground strap and bypass contact design are built to maintain consistent contact pressure on #12–#10 AWG copper conductors over time.
