100 A Dockside Receptacle

This Hubbell receptacle delivers 100 A at 125/250 V AC for shore-power connections on commercial and recreational vessels. Its IEC grounding style and IP67 rating protect live contacts from water ingress in wet marina environments. The grey thermoplastic housing resists UV and corrosion while meeting NEMA 4X requirements. It is built for installers who need a single-gang, straight-orientation inlet that accepts 3 AWG to 1/0 AWG conductors.

IP67 Spring-Loaded Cap Upgrade

The spring-loaded cap replaces older screw-on or flip-lid covers that can be left open or cross-threaded in rough conditions. When the plug is removed the cap snaps shut automatically, restoring the IP67 seal without operator effort. This jump is worth it on high-traffic docks where crews connect and disconnect daily and cannot risk a missed latch. The flanged mounting pattern matches legacy Hubbell cut-outs so no new drilling is required.

3-Pole 4-Wire Single-Phase Limits

The device provides three poles and four wires for single-phase 125/250 V service only; it cannot supply three-phase loads or higher voltages. Maximum conductor size is 1/0 AWG, so feeder runs beyond that ampacity need a larger receptacle series. The 4.71 in face diameter fits standard single-gang boxes but leaves no room for adjacent devices on the same plate. No power-indicating light is fitted, so visual confirmation requires a separate meter or panel indicator.

Questions about this item

Will the 4.71 in face diameter fit my existing dockside cut-out?

The receptacle face measures 4.71 in across, so compare that diameter to your panel opening before ordering.

How do I wire the 100 A receptacle correctly, and what step is often missed?

Strip 3 AWG to 1/0 AWG conductors, insert fully into the IEC-grounded sleeves, torque the terminal screws to spec, then snap the spring-loaded cap shut to seal the IP67 rating.

What part will need replacement after seasons of salt-spray exposure?

The gray thermoplastic housing and spring-loaded cap resist corrosion, but the cap gasket should be inspected yearly and replaced if it loses elasticity.
