Hubbell RACO 175 Octagon Box

The Hubbell RACO 175 is a galvanised steel octagon electrical box with a 21.5 cubic inch capacity. It is UL 514-A listed and carries standards file E195978. The box features four NM-B clamps, one 1/2 inch back knockout and two 1/2 inch side knockouts. It is suited for residential or light commercial wiring where a standard octagon junction point is required.

Installers needing a two-gang octagon box

This unit fits projects that call for a two-gang octagon enclosure with integral NM-B cable clamps. Electricians who require a different gang count, alternative bracket styles or larger knockout configurations should select another model. The fixed clamp and knockout arrangement limits flexibility for non-standard cable entry.

21.5 cubic inch capacity for wire fill

The 21.5 cu in volume accommodates typical lighting circuits and receptacle splices within NEC fill limits. It provides headroom for multiple conductors and device yokes in a standard octagon footprint. Circuits with high conductor counts or bulky connectors may exceed the available space, requiring a larger capacity enclosure.

Questions about this item

Does the RACO 175 box include a mounting bracket or must I supply one?

The box has no integral bracket; it mounts directly to framing with screws or nails through the box ears.

Can I use the existing 1/2 in. knockouts on this 21.5 cu. in. octagon box for older NM cable?

Yes, the box provides one 1/2 in. back knockout and two 1/2 in. side knockouts that accept standard NM-B cable.

How do I verify the RACO 175 is properly listed after installation?

Look for the UL 514-A listing mark and standards file E195978 stamped on the galvanised steel body.
