ABB 54531-1/2&3/4 – Frequently Asked Questions

1) Can this ABB octagon box be poured directly into a concrete slab?
Yes, that is what the ABB octagon concrete box is built for. It is a pre-galvanized steel box with drawn (seamless) construction, which is what lets it stand up to wet concrete pours in slab and wall assemblies without the seams that a formed-and-welded box has. It is intended for conduit runs, not cable, so your raceway lands in one of the knockouts before the pour.
2) Is this octagon concrete box UL listed for commercial and institutional work?
It carries UL listing E2969, which is the file number an inspector or a spec writer will want to see on a concrete-embedded outlet box. That listing is stated on the product record, not inferred.
3) Will a pre-galvanized steel box corrode in concrete?
The body is galvanized steel, and the zinc coating plus the drawn one-piece construction are why this box is specified for concrete rather than a plain steel box. If your application is direct earth burial or a wet, corrosive exposure outside of the slab, that is a different product class and this box is not the answer for it.
4) Can I mount two devices in this ABB octagon box?
No. It is configured for one outlet per box, so plan on a single device, fixture, or junction point. For two devices you need a different box configuration.
5) Is an octagon box the right choice, or should I use a square box for this concrete pour?
A 4 inch octagon like this one is the standard shape for a ceiling fixture outlet or a straight conduit junction, and the 4 inch round pattern matches typical fixture canopies and round covers. A 4-11/16 or 4 inch square box is the usual pick when you need more cubic capacity or a raised device ring for receptacles and switches. With 23 cubic inches and a single-outlet configuration, this octagon suits fixture and junction points rather than multi-gang device work.
6) What color is the ABB octagon concrete box, and does it need a cover ordered separately?
The finish is silver, the natural look of the pre-galvanized steel. A cover or fixture plate is not part of the box itself, so order the round or octagon cover to suit the device or fixture you are landing on it.
