Abb BH235A 2-gang Heavy Wall Electrical Box

Product Description

The ABB BH235A is a 2-gang heavy-wall electrical box with a 35 cubic inch interior volume, designed for residential and light commercial wiring installations. The heavy-wall construction provides added durability and impact resistance compared to standard-duty boxes, making it suitable for applications where the enclosure may be subject to physical stress during or after installation. Licensed electricians and electrical contractors install this box as part of new construction or retrofit wiring projects where a larger-volume enclosure is required to accommodate multiple devices, conductors, or wire connectors without exceeding fill capacity limits under the NEC.

This box is used in wall installations where two devices — such as receptacles, switches, or combination devices — must be mounted side by side. The 35 cubic inch volume provides sufficient fill capacity for circuits with multiple conductors, clamps, and device yokes as calculated per NEC Article 314. It is appropriate for residential new construction, remodel work, and light commercial applications where a robust, larger-capacity 2-gang enclosure is specified.

Key Features

• 35 cubic inch interior volume supports higher NEC conductor fill calculations for 2-gang device installations
• Heavy-wall construction offers greater impact resistance than standard-duty boxes
• 2-gang configuration accommodates side-by-side mounting of switches, receptacles, or combination devices
• Designed for wall installation in residential and light commercial electrical systems

Compatibility

Designed as an OEM-style replacement and standard new-installation 2-gang electrical box for use with common residential and light commercial wiring devices including switches, receptacles, and combination devices that mount to a standard 2-gang box.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 314 and all applicable local codes. De-energize the circuit at the panel before any wiring work inside the box. Verify conductor fill does not exceed the rated 35 cubic inch volume using NEC fill calculation methods. Secure the box to framing or blocking as required by local code before pulling conductors.
