Single-Gang Weatherproof Box

The Bell 5330-0 is a single-gang aluminum enclosure rated for outdoor use. It provides 16.5 cu in of internal capacity for wiring connections in damp or wet locations. The gray finish resists corrosion in exposed environments. It suits electricians and DIYers running conduit to exterior fixtures.

Four Inlets with 3/4 in Hubs

Four 3/4 in threaded hubs allow conduit entry from multiple directions without extra fittings. This layout reduces the need for separate junction boxes or conduit bodies in branching runs. The integrated hubs simplify installation and maintain the weatherproof seal at each entry point. Standard CSA and UL listings confirm compliance for outdoor branch circuits.

Dimensional Constraints for Device Fit

The 4.5 in length, 2.75 in width and 2 in depth limit the size of switches, receptacles or timers that can be mounted inside. Builders needing deeper enclosures for GFCI devices or smart modules should verify internal clearance before purchase. The fixed hub size prevents adaptation to 1 in or 1/2 in conduit without reducers. Capacity is fixed at 16.5 cu in, so conductor fill calculations must stay within that limit.

Questions about this item

Does the aluminum housing or the 3/4 in hub need periodic replacement?

The aluminum box and 3/4 in hub are built for permanent outdoor installation and do not have a scheduled replacement interval.

What limits continuous use of the 16.5 cu in capacity?

The 16.5 cu in volume sets the maximum conductor fill; exceeding it violates CSA and UL standards and creates the first limitation under sustained load.

Does the gray aluminum enclosure dissipate heat when cables run all day?

Aluminum construction naturally conducts heat away from conductors, and the weatherproof design maintains safe operating temperatures during continuous use.
