Square 30.3 cu in box

This 4-inch square electrical box provides 30.3 cubic inches of internal volume for splicing or device mounting. It is constructed from 1/16-inch pre-galvanized steel with welded corners for rigidity. The unit suits residential or light-commercial rough-in work where a two-gang capacity is required. Model 231 ships new and ready for installation.

Sustained load behaviour

The galvanized coating resists corrosion during long-term exposure to damp or humid locations. Welded seams maintain structural integrity when the box is filled to its 30.3 cu in limit with conductors and devices. Cover mounting screws are assembled at the factory to stay secure under thermal cycling. The steel wall thickness does not deform under normal tightening torque.

Knockout layout limits

One 1/2-inch and eleven 3/4-inch knockouts define the maximum conduit entry points for this box. Installers must plan cable routing within those sixteen openings because no additional holes can be added without compromising the listing. The fixed pattern may restrict designs that need more or differently sized entries. External clamps or bushings are not included.

Questions about this item

Does the 30.3 cu in volume of the RACO 231 electrical box leave enough space for heat to dissipate when wires run continuously?

The 30.3 cu in capacity provides the code-required free air volume for the conductors you install, so heat buildup stays within safe limits for standard residential circuits.

What mounting hardware must I already have to secure this 2-gang box to a stud or joist?

The box ships with 8-32 cover mounting screws assembled; you supply the nails or screws driven through the welded side brackets into the framing member.

Will the mixed 1/2 in. and 3/4 in. knockouts on this galvanized box line up with the older conduit sizes already in my walls?

One 1/2 in. and eleven 3/4 in. knockouts are provided, matching the common conduit sizes used in legacy installations.
