What is Gang Box?

Even though both interpretations of the term “gang box” have to do with building activity, they are pretty different. A gang box is a sizable toolbox that a work team may utilize, including all its members. A gang box is a plastic or metal container used in electrical operations to store electrical components safely.

A gang box toolkit only has a small number of unique features. Endurance and security are crucial in constructing these boxes because they are frequently left on such a job site where they must withstand a lot of abuse and be challenging to break into.

These boxes, which are often larger than standard toolboxes so they can hold all the necessary tools and materials, are typically maintained by, at minimum, a few workers.


The gang box is one of the many boxes used to encapsulate wire and another renovation wiring securely. The number of suspension components for switching or receptacle that this sort of gang box contains will typically be used to identify it. Although larger boxes aren’t unheard of, gang boxes are often found in various sizes, from single to three gangs.

Exception cases

There are some exceptions to the general principle that just one unique switch or connector can be placed in a gang box under current electrical practices.

Some gang boxes are composed of plastic and are typically used with a cable that is sheathed in non-metallic materials. The most typical gang box used in contemporary residential construction is this one, primarily due to its affordability and simplicity of installation. It is necessary to utilize a distinct ground wire with this kind of box.


Since metal gang boxes are significantly more durable than their plastic counterparts, they may be used for any form of electrical work. They more frequently found in older buildings, commercial buildings, or locations where the electrical work may be damaged.

While metal boxes are often built such that one edge of the box can be withdrawn. Another box attached to make a larger box, making metal boxes extremely adaptable in some scenarios, these boxes are available with the exact basic dimensions as plastic boxes. When steel conduit or armored cable is used for electrical work installation, along with metal boxes, the lines or cable can frequently legally act as a grounded path without needing a ground plane.

Ganging Electrical boxes

Some electrical boxes can be joined together (ganged) to create double-gang, triple-gang, or perhaps even quad-gang electrical boxes with a bit of fiddling. Because metal boxes are frequently used for masonry walls, the traditional gang able box is made of metal. It is occasionally referred to as a “masonry box.”

Structure of ganging electrical boxes

In reality, however, all forms of construction, especially conventionally framed baseboard trim walls, utilize these gangable metal boxes. Due to their versatility and lack of requirement for double-gang & triple-gang boxes to be kept on standby, experienced electricians carry a sizable stock of gangable boxes.

Additionally, plastic snap-together boxes are accessible, but you may need to go to a retail outlet that provides electrical equipment to discover them, as most household construction supply stores do not carry them. The steel-type gangable boxes are the most widely accessible in home centers and hardware stores and are suitable for all uses.

Gangable boxes are manufactured in designs suitable for retrofit installations and construction projects; the latter is frequently referred to as an “old-work” box.

  • Take off the grill grate set screw first.
  • You must first unscrew the set screw from the box’s other side that will be attached to an adjacent box to join 2 or maybe more gangable boxes together. The detachable side plates are secured in place by these set screws. You would need the screws once more to join the boxes, so set them aside.
  • You will detach the left-side plate from one box and the right-side container from the other if you combine two solitary packages to create a double pack.

Get rid of the side plates

Pull and carefully twist the lateral plate away from the electrical box from the side where the set screw was removed. When the setup screw is attached, most types have tiny overlapping bent flanges that hold the sides in place; however, when the set screw is removed, you can easily pull the side plate free by giving it a different twist. Other box designs may have tabs and slots holding the side plates to the box; in this case, you only need to slide the side plate out to release it.

The side panels for the combination electrical box are not necessary, so you are free to recycle them.

Keep them on hand as replacement parts

Many resourceful householders have discovered surprising uses for these tiny plates.

Participate in single electrical boxes

The electrical boxes’ open sides should face each other as you slide them together. They will have curved tabs or slots to aid in a tight fit. To be code-compliant, the boxes must form a complete enclosure; therefore, make sure that there aren’t any gaps between them.

The set screws you previously removed are used to secure the box joints. Compress them tightly with the screwdriver. The finished box is now prepared for installation.
