Abb B120A-UPC 1-gang Pvc Nail-on Switch Box 20 Cu in

Product Description

The ABB B120A-UPC is a 1-gang, 20 cubic inch blue PVC nail-on wall box designed for new construction electrical rough-in work. The box ships with captive nails already installed, allowing electricians to drive the box directly into wood framing without separate fasteners. Its non-metallic PVC construction eliminates the need for grounding the box itself, which simplifies wiring in residential and light commercial applications. The 20 cubic inch volume meets NEC fill-capacity requirements for standard single-gang device configurations including switches and receptacles.

This box is suited for new-construction framing installations where the stud face will be covered by drywall or other finish material. Electricians and residential wiremen typically install this type of box during rough-in, nailing directly to wood studs before wall surface material is applied. The nail-on design keeps the workflow fast on production framing jobs.

Key Features

• 1-gang configuration fits standard single switches and receptacles
• 20 cubic inch interior volume supports NEC conductor fill calculations
• Blue PVC construction is non-metallic and does not require box grounding
• Captive nails pre-installed for direct attachment to wood framing
• Designed for new construction nail-on applications

Compatibility

Designed as an OEM-style replacement and standard new-construction nail-on box compatible with single-gang devices such as switches and receptacles in residential and light commercial framing applications.

Installation Notes

Installation is performed by a licensed electrician during the rough-in phase before wall surfaces are applied. Drive the captive nails into the face of a wood stud so the front edge of the box is flush with the planned finished wall surface. Follow NEC box fill requirements when determining conductor count. Do not use this box in applications requiring a metallic enclosure or equipment-ground continuity through the box itself.
