Industrial Power Receptacle

The Hubbell HBL5100RS1W is a 100A 600V AC pin and sleeve receptacle built for industrial environments. It provides a grounded, four-pole, five-wire connection with a watertight, impact-resistant thermoplastic housing and a spring-loaded cap for ingress protection.

Three-Phase Equipment Installers

This device suits electricians wiring three-phase machinery or distribution panels that require a 100A flanged inlet with Style 1 grounding. It is not for installers needing a NEMA-rated enclosure, a different pole count, or a voltage rating outside the specified 600V AC and 250V DC range.

Flanged Panel Mounting

The receptacle mounts via its integral flange and accepts conductors from 8 AWG to 2 AWG. The shrouded pins and spring-loaded cap simplify alignment and sealing, though the 4.71 in face diameter demands adequate panel space and the maximum wire size may limit use with larger feeder cables.

Questions about this item

What cable gauge range must I have on hand to wire the 100 A receptacle terminals?

The terminals accept conductors from 8 AWG up to 2 AWG, so your supply cable must fall inside that range.

Will the 4-pole, 5-wire flange mate with my existing 3-phase, 600 V AC pin-and-sleeve plugs?

Yes — the receptacle is built for three-phase, 600 V AC service with four poles and five wires, matching standard industrial pin-and-sleeve plugs of that rating.

How can I confirm the spring-loaded cap is sealing properly after installation?

Close the cap and verify it snaps shut with spring tension; the watertight, impact-resistant housing should show no gaps around the flange when the cap is engaged.
