In the context of electricity, the term gang is used to describe the number of switches or circuits within an electrical box. The usage of the term varies internationally and depending on the context. In the US, gang often refers to the physical size of the circuit box or the width of the box, with each gang indicating the number of standard switches or receptacles the box can accommodate. In other contexts, gang may refer to the number of switches or circuits within a box, irrespective of its physical size. For example, a 2-gang box could refer to a box that contains two switches or circuits. Understanding the meaning of gang is essential when working with electrical systems to ensure the correct components are selected and installed.

'Gang' refers to the number of circuits in a circuit box
The term "gang" is used to refer to the number of circuits in a circuit box. This usage of the term is common internationally, except in the US. In the US, "gang" refers to the physical size of the circuit box, indicating how many standard switches or receptacles the box can accommodate.
A single-gang or 1-gang box is wide enough to fit a single switch or outlet. A 2-gang box can accommodate two devices side by side, and so on. In the UK, the n-Gang terminology is similar, but the sockets are bigger and not usually stacked on top of each other. For example, a 2-gang box in the UK is wider than a 1-gang box and has two sockets.
The number of gangs in a box can go up to 8 or 10, depending on the source. However, it is uncommon to have more than three gangs in a domestic setting.
It is important to note that the term "gang" can also refer to the number of switches on a plate, sometimes called rockers, throws, or dimmers. A 1-gang dimmer switch, for instance, will have a single dimmer on the plate, while a 2-gang dimmer switch will have two dimmers.

The number of switches on a plate
In the context of electrical wiring, the term "gang" refers to the number of switches or outlets controlled or housed by a single box. In other words, it indicates how many switches or outlets are grouped together in one box. This terminology is used to describe various electrical components, such as light switches, electrical sockets, and circuit boxes.
Now, let's delve into the specifics of the number of switches on a plate:
1-Gang or Single Gang
A 1-gang switch plate features a single switch that controls a single lighting circuit. It is typically used in rooms with only one lighting circuit, allowing you to turn the lights in that space on or off. This type of switch is the most common in residential settings, as most homes have "single pole switches" that serve basic lighting needs.
2-Gang or Double Gang
A 2-gang switch plate accommodates two switches, often referred to as "2-way switches." This configuration allows you to control two individual lighting circuits from a single plate. For example, you might have a 2-gang switch at the top and bottom of a staircase to control a landing or stairway light, enhancing safety and convenience.
3-Gang
While less common in domestic settings, 3-gang switch plates feature three switches on a single plate. These switches are typically 2-way switches, allowing you to control the same light source from three different locations. This setup is useful for large rooms with multiple entrances, ensuring a light can be turned on or off from any of the entrances.
Higher Gang Switches
Although less common, it is possible to have higher gang switches, such as 4-gang, or even up to 10-gang switch plates. These configurations are typically found in commercial or industrial settings where multiple circuits or devices need to be controlled from a central location.
It's worth noting that the physical size of the switch plate and the box it is mounted on may vary depending on the number of gangs. For example, in the UK, a 1-gang box is designed to fit a single switch, while a 2-gang box can accommodate up to four switches. In the US, the gang terminology often refers to the physical size of the box, with each gang representing a standard width that can accommodate a certain number of switches or outlets.

The physical size of the box
The term "gang" in electrical wiring refers to the number of switches or outlets that can be accommodated by an electrical box. While the specific dimensions may vary based on geographical location, the fundamental concept remains consistent: a higher gang count indicates a larger physical size for the box.
In the United States, the gang designation is closely tied to the physical width of the box. This correlation is a result of the prevalent construction practice of adhering to a single circuit per standard fixed box width. Consequently, the term "gang" has evolved to signify width rather than the explicit count of circuits. This approach offers the advantage of simplified customization and replacement of circuits.
In the United Kingdom, the n-Gang terminology is also employed, albeit with subtle differences. UK plugs are generally larger and not typically stacked, resulting in distinct socket dimensions from those in the US. Nevertheless, the fundamental principle of gang denoting the number of sockets or switches remains consistent.
The international interpretation of the term "gang" is primarily associated with the count of circuits within a box, irrespective of its physical size. This usage is prevalent outside of the US and the UK, where construction standards and electrical component designs may differ.
It is worth noting that the gang designation can also be applied to switches themselves. A 1-gang switch, for instance, features a single switch button, while a 2-gang switch offers two switch buttons, and so forth. This nomenclature is consistent with the broader concept of "gang" referring to the quantity or capacity of electrical components.

The width of the box
In the US, the "gang" terminology is used to refer to the physical size of the circuit box. The number of "gangs" indicates how many standard switches or receptacles the box can fit. For example, a 1-gang box is wide enough for a single switch or outlet, while a 2-gang box can accommodate two devices side by side.
In the UK, the "gang" terminology is also used, but with a slightly different meaning. UK plugs are bigger and not usually stacked, so a 2-gang box is wider than a 1-gang and has two sockets. The dimensions differ from those in the US.
On an international level, "gang" typically refers to the number of circuits within a box, regardless of its physical size. So, a 1-gang box may have one switch that controls a single lighting circuit, while a 2-gang box can control two individual lighting circuits.
It is worth noting that the width of the box is not always a precise indicator of the number of outlets or switches. For example, with 3-gang or 4-gang boxes, the sizes of the boxes may not match the number of outlets that can fit inside.

The number of outlets in a box
The term "gang" in the context of electrical boxes refers to the number of switches or outlets that can be accommodated within the box. A single-gang or 1-gang box is wide enough for one switch or outlet, while a double or 2-gang box can hold two devices side by side. This terminology is used internationally, but with some variations.
In the UK, the n-Gang terminology is similar to that of the US, but the physical dimensions of the boxes and sockets differ. UK plugs are larger and not usually stacked, so a 2-Gang box is wider than a 1-gang and has two sockets. For switches, the term refers to the number of switches, and a 1-gang, 2-gang, or 3-gang switch may be the same size but have a varying number of switch buttons.
In the US, "gang" often refers to the physical size of the circuit box. With standard-width switches and receptacles, the "gang" indicates how many of these can fit in the box. For instance, a 2-gang box in the US is twice the width of a 1-gang box, and a 3-gang box is three times the width.
However, it is important to note that the relationship between the number of gangs and the size of the box can become less consistent with larger boxes. For example, a 3-gang or 4-gang box may not always match the expected size based on the number of outlets it can accommodate.
Additionally, the term way is sometimes used in conjunction with "gang" to describe the functionality of the switches. A "2-way switch" means that two switches control a single lighting circuit, which is often used for staircases or large rooms with switches by each door.
