Marine Angle Back Box

The Hubbell BB100N is a cast-metal angle back box built for 100/125A IEC pin-and-sleeve devices in marine environments. It provides generous wiring space and a secure grounding path to metallic conduit. The 1-1/2" NPT hub accepts standard conduit fittings. Rated for industrial-grade service in wet locations.

Upgrade From Straight Boxes

Installers replace straight back boxes when conduit must enter at an angle to clear deck structures or bulkheads. The angled hub reduces cable bending radius and eases wire pulling in tight compartments. The change is worth it when a straight entry would force sharp bends or exceed conduit-fill limits.

Conduit And Current Limits

The single 1-1/2" NPT hub restricts the maximum conduit size to that trade diameter. The box is rated for 100/125A circuits, so it cannot serve higher-amperage shore-power inlets. Only one conduit entry is provided, preventing daisy-chained runs through the same enclosure.
