Hubbell HBL420I 4-PLEX Quad Outlet

The Hubbell HBL420I 4-PLEX receptacle provides four NEMA 5-20R straight-blade outlets in a single surface-mount unit. It is rated for 20 A at 125 V AC and suits commercial or industrial environments where multiple devices must connect at one location. The polycarbonate housing meets UL94 V-2 flammability requirements and operates from -40 °C to +75 °C.

Capacity and headroom for four 20 A loads

Each of the four outlets delivers the full 20 A rating, and the assembly is listed to UL 498 for fault levels up to 1000 A with 2000 V dielectric strength. Brass triple-wipe contacts and a #8-32 brass ground screw maintain reliable connectivity under continuous load. Back-wired screw terminals accept #12 AWG solid or stranded copper conductors, so wiring capacity matches the device rating.

Upgrade from single or duplex receptacles

Replacing a single or duplex outlet with this quad unit adds two or three extra connection points without new circuit runs. The included adapter plate and portable box simplify surface mounting on walls or equipment. The jump is worthwhile when a workstation, bench or machine needs four grounded plugs in one enclosure and the existing wiring already supports a 20 A branch circuit.

Questions about this item

Will the Hubbell HBL420I quad receptacle work with my existing 20A branch circuit and #12 AWG copper wiring?

Yes, the receptacle is rated 20A 125V AC and its back-wired screw terminals accept #12 AWG stranded or solid copper conductors, matching a standard 20A branch circuit.

How can I verify the HBL420I is functioning correctly after installation?

With power on, measure 125V AC across each hot and neutral slot of the four NEMA 5-20R outlets and confirm continuity from the ground slot to the green #8-32 brass ground screw.

Does the HBL420I include the surface-mount box and adapter plate, or must I buy them separately?

The product ships with the surface-mount adapter plate and portable box included, so no separate mounting accessories are required for a standard surface installation.
