The THOMAS BETTS E9812D is a 2-gang square electrical switch box constructed from polyvinylchloride (PVC) for weather-resistant performance in demanding installation environments. Measuring 4.62 inches in overall height, 4.62 inches in overall width, and 1.98 inches in overall depth, this box provides a compact yet functional enclosure for multiple devices. It includes two 1/2-inch knockouts for conduit entry, allowing flexible routing of wiring. The box is rated weather-resistant, making it suitable for installations where moisture exposure is a factor. Licensed electricians and experienced electrical trades professionals are the primary installers of this component.
This switch box is intended for use in residential and light commercial electrical installations where a square, 2-gang configuration is required. Its PVC construction resists corrosion and is well suited for damp or outdoor-adjacent locations. The 2-gang layout accommodates two devices side by side, such as switches or receptacles, within a single box footprint. The square profile simplifies rough-in work in new construction and retrofit applications.
Designed as an OEM-style replacement or standard new-installation switch box compatible with 2-gang square cover plates and devices conforming to standard electrical box mounting configurations.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Shut off circuit power at the breaker panel and verify the circuit is de-energized before mounting or wiring the box. Use appropriate conduit fittings sized for the 1/2-inch knockouts and ensure the box is securely fastened to the mounting surface before pulling wire. Do not exceed the box fill capacity as calculated per NEC Article 314.
