Electrical box with 15.5 cu in capacity

This galvanized steel octagon box provides 15.5 cubic inches of wiring space for residential or light commercial electrical installations. The two-gang design accommodates multiple devices or switches in a single enclosure. UL listing confirms compliance with safety standards for indoor use.

Upgrade from single-gang octagon boxes

Replacing a single-gang octagon box with this two-gang model doubles device capacity without enlarging the ceiling or wall opening. The jump is worth it when adding a second switch, receptacle or combination device in the same location. Existing 1/2 inch side knockouts simplify cable entry during retrofit work.

Capacity and headroom for typical lighting circuits

The 15.5 cu in volume comfortably handles conductors for standard lighting circuits and multiple device combinations within fill limits. It runs out when conductor count or device size exceeds NEC box-fill calculations for the installed wire gauge. Deep 1 1/2 inch nominal depth helps accommodate deeper devices or wiring folds.

Questions about this item

Will the 4 in by 4 in octagon box fit between standard studs?

The 4 in nominal length and width match typical stud cavities, but verify local spacing before mounting.

Which knockout do I remove for the first cable run?

Use the two 1/2 in side knockouts with the built-in KO and NMSC clamps; the back has none.

When should I replace the galvanized steel box?

Replace if the gray coating shows white rust, the clamps no longer grip cable, or the box is bent.
