Hubbell HBL53CM61 5-20R Receptacle

The Hubbell HBL53CM61 is a 20 A straight-blade receptacle with a NEMA 5-20R configuration. It features a corrosion-resistant nylon face in yellow and provides an isolated ground connection. The single-gang device mounts flush and accepts three wires for single-phase polarised operation. It carries a NEMA 1 enclosure rating and has no GFCI protection built in.

For commercial wiring needing isolated ground

This receptacle suits electricians and facility managers installing dedicated circuits that require isolated grounding to reduce electrical noise. The yellow housing allows quick visual identification of specialised circuits in panels or work areas. It is not for buyers who need ground-fault protection, a weather-resistant cover, or a multi-gang configuration. Residential users seeking a standard duplex outlet should look at something else.

Key spec: NEMA 5-20R 20 A isolated ground

The defining specification is the NEMA 5-20R rating combined with an isolated ground terminal. This pairing determines whether the device matches the circuit design and plug type required by the connected equipment. Verify that the branch circuit is rated for 20 A and that the wiring plan calls for an isolated ground before selecting this part.

Questions about this item

What wiring must already be in place for this 5-20R receptacle to work?

A 20 A single-phase circuit with three wires (hot, neutral, ground) and a flush-mounted box is required for the straight-blade 5-20R configuration.

Will this yellow nylon receptacle fit in a standard wall box used by older devices?

Yes, it mounts in a standard single-gang flush box and the NEMA 5-20R face matches existing cover plates.

How can I confirm the isolated ground is functioning after installation?

Measure continuity between the ground terminal and the metal box; the isolated-ground design should show no continuity when correctly wired.
