Double-gang box for outdoor wiring

This 31 cu in aluminum box provides two gangs for switches or receptacles in damp locations. The gray finish and UL listing confirm it meets standard safety requirements for exposed installations. It is suited to electricians and DIYers running surface-mounted circuits on exterior walls.

Not for single-gang or low-capacity needs

Builders who only need one device opening should choose a single-gang box instead. Projects that require more than 31 cubic inches of fill capacity will need a larger enclosure. The aluminum body is not intended for direct burial without additional protection.

31 cu in capacity decides fit

The 31 cubic-inch volume determines how many conductors and devices the box can legally contain under code. Verify the total conductor count against this limit before purchasing. The double-gang layout then dictates the cover and device options available.

Questions about this item

Will the aluminum housing or the gasket on the 5343-0 box need periodic replacement?

The aluminum body is corrosion-resistant and the factory-sealed gasket is designed for the life of the installation; no scheduled replacement is required.

What capacity limit will be reached first when adding conductors to this 31 cu in double-gang box?

The 31 cubic-inch volume is the governing fill limit; conductor count must stay within NEC box-fill calculations for that capacity.

How much heat does the Bell 5343-0 dissipate when circuits run continuously?

The aluminum enclosure acts as a heat sink for the wiring inside; it adds no active thermal load and remains at ambient temperature during normal operation.
