Hubbell RACO 175 Octagon Electrical Box 21.5 cu in

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.
