Raco 8189 2-gang Ceiling Outlet Box 16-knockout Steel

Product Description

The RACO 8189 is a 2-gang steel outlet box designed for ceiling-mount electrical installations. Constructed from pre-galvanized steel at 1/16 inch wall thickness, it provides a durable enclosure for wiring, switches, receptacles, and lighting fixtures. The box ships with 8-32 cover mounting screws pre-assembled, saving time on installation. At 21 cubic inches of interior capacity and 16 available knockouts for conduit entry, the 8189 gives electricians flexible routing options without requiring field modifications to the box body.

The RACO 8189 is suited for residential and light commercial ceiling applications where a square, flush-mount outlet box is required. Its conduit-entry configuration makes it a natural fit for EMT and rigid conduit systems in finished ceilings, junction points, and fixture rough-ins. The square 4-inch footprint aligns with standard mud rings and covers used in commercial electrical work, making it a common choice for electricians working under NEC guidelines for box fill and device mounting.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage before working inside or near the box. Conduit entries should be properly fitted with approved connectors to maintain the integrity of the wiring method. Confirm box fill calculations per NEC Article 314 before filling the box with conductors and devices.
