Single-Gang 18.3 cu in Capacity

The Bell 5331-0 is a single-gang weatherproof electrical box offering 18.3 cu in of internal capacity. Constructed from aluminium with a gray finish, it is designed for outdoor installations where moisture resistance is required. The box is CSA certified and UL Listed for safety compliance. It suits electricians and DIYers running a single device circuit in exposed locations.

Aluminium Construction and Sustained Exposure

The aluminium body resists corrosion during prolonged outdoor exposure better than non-metallic alternatives. Its rigid structure maintains sealing integrity against driving rain and temperature cycling without warping. The 18.3 cu in volume accommodates wiring for a single gang device without overcrowding. CSA and UL listings confirm the enclosure meets sustained wet-location requirements.

Single-Gang Device Limitation

The single-gang format restricts the box to one switch, receptacle or similar device per unit. Installers needing multiple devices must use separate boxes or a multi-gang enclosure not covered by this model. The 18.3 cu in capacity sets a hard limit on conductor fill under electrical code rules. No additional gangs or expansion options are provided with this specific unit.
