What is a double gang box?

A double gang box is specifically designed to accommodate two devices installed side by side. This type of box typically has two sets of terminals or mounting holes that allow for the secure installation of outlets, switches, or other electrical devices. The key feature of a double gang box is its increased width compared to a single gang box, which allows for this dual-device configuration.

Additionally, the use of double gang boxes is common in residential and commercial settings where multiple devices are needed in close proximity, such as in a wall with a pair of light switches or outlets. This design helps organize wiring and provides a neater appearance while ensuring compliance with electrical codes.

In contrast to the other options, a double gang box is not limited to outdoor use, does not serve solely as a junction box, and is not intended for just a single device. Its primary function is to provide a structured space for two devices to coexist, thereby simplifying installation and enhancing usability.
