Bell Outdoor 5320-0 Weatherproof Electrical Box 1 Gang 1/2 in Hub Size Gray Aluminum 18.3 cu in

Outdoor Electrical Box, 1-Gang Aluminum

The Bell Outdoor 5320-0 is a weatherproof electrical box designed for exterior wiring connections. Its single-gang configuration and gray aluminum construction suit residential and light-commercial installations where moisture resistance is required. The box meets CSA and UL Listed standards for safety compliance. It provides a durable enclosure for switches, receptacles or junction splices in damp or wet locations.

Upgrade from Non-Weatherproof Boxes

This unit replaces standard indoor boxes when a circuit moves outdoors or into damp areas such as patios, garages or garden lighting runs. The jump is worth it whenever local code demands a listed weatherproof enclosure or when exposure to rain, sprinklers or condensation would corrode an unsealed box. The 18.3 cu in capacity accommodates typical device-and-wire combinations for single-gang applications. Builders needing multiple devices in one enclosure should select a multi-gang model instead.

1/2 in Hub and Capacity Limits

The box uses a 1/2 in hub size for conduit or cable entry, so all raceways and fittings must match that trade size. Its 18.3 cu in internal volume sets the maximum conductor fill permitted by code; exceeding that fill requires a larger box. The aluminum material resists corrosion but cannot be used where direct burial without conduit is specified. Installers must verify that the hub orientation and mounting ears suit the surface and wiring plan before purchase.
