Hubbell IG2310 Isolated-Ground Receptacle

The Hubbell IG2310 is a 20 A, 125 V AC single-phase locking receptacle with an isolated ground that separates the grounding contact from the mounting strap to reduce electrical noise. It uses a NEMA L5-20R twist-lock configuration and accepts 16 to 8 AWG solid or stranded copper wire via screw terminals. Industrial electricians and facility managers specify it for equipment that requires a secure, noise-resistant connection.

Upgrade from Standard Non-Isolated Receptacles

This receptacle replaces standard locking outlets where ground-loop noise or vibration-related loosening causes intermittent faults. The isolated-ground construction and impact-resistant nylon housing justify the change when sensitive electronics share a circuit with heavy loads or when the mounting surface conducts stray currents. It is not for installations that lack a dedicated insulated ground conductor or that use a different NEMA pin configuration.

Flush-Mount Install with Back or Side Wiring

The device mounts flush with included screws and supports both back and side wiring methods for conductor routing flexibility. A dedicated insulated ground wire must be run to the isolated terminal; omitting it defeats the noise-reduction purpose. Common errors include terminating the ground on the strap instead of the isolated contact and failing to fully seat the twist-lock plug, which can leave the circuit open under load.

Questions about this item

What size wall box fits the IG2310 flush-mount receptacle?

The IG2310 is designed for flush-mount installation with included screw hardware; use a standard single-gang box that accepts a 20 A, 125V AC device.

Which wiring method and gauge range does the L5-20R receptacle accept?

The IG2310 accepts #16 AWG to #8 AWG solid or stranded copper wire via screw terminals and supports both back and side wiring methods.

What maintenance does the isolated-ground locking receptacle require over time?

Periodically inspect the orange nylon housing for cracks, verify brass contacts remain tight and corrosion-free, and confirm the dedicated insulated ground wire stays securely terminated.
