In the context of electrical work, the term one gang is used to describe a type of electrical box or switch configuration. It refers to the width of the box, which can accommodate a single switch or outlet device. This terminology is used in both the US and UK, but with some differences in meaning and design. In the US, gang often refers to the physical size of the circuit box, with each gang representing a standard width that can accommodate a certain number of switches or receptacles. In the UK, a 2-gang configuration is wider than a 1-gang and typically has two sockets, but the dimensions differ from those in the US. Understanding the meaning of one gang in electrical work is important for tasks like sizing electrical boxes and installing switches or outlets.

What You'll Learn
Gang refers to the number of switches on an electrical box plate
The term “gang” is used to refer to the number of switches or outlets on an electrical box plate. A “1-gang” box, for instance, is wide enough to fit only one switch or outlet, while a “2-gang” box can accommodate two devices side by side. This terminology is used in both the US and the UK, but with some differences.
In the US, the term "gang" also refers to the physical size or width of the circuit box. This is because US construction generally follows the rule of one circuit per standard fixed box width, so the term "gang" has evolved to indicate width rather than the number of circuits. This means that a 2-gang box in the US is twice as wide as a 1-gang box, and a 3-gang box is three times as wide.
In the UK, the n-Gang terminology is similar, but since UK plugs are larger and not usually stacked, a 2-gang box is roughly 1.5 times the width of a 1-gang box, and a 3-gang box is roughly twice the width of a 2-gang box. For switches, the number of gangs indicates the number of switch buttons, so a 1-gang switch has one button, a 2-gang switch has two buttons, and so on.
It is important to note that the term "gang" can be confusing, especially when dealing with 3 or 4-gang boxes, as the sizes of the boxes may not always match the expected number of outlets. Additionally, the term “double gang” or "2-way switch" refers to a situation where two switches control a single lighting circuit, such as having a light switch at the top and bottom of a staircase.

It can also refer to the physical size of the box
The term "gang" in electrical work can refer to the number of switches or outlets in an electrical box. However, it can also refer to the physical size of the box itself.
In the US, the term "gang" is often used to describe the size of a circuit box. The number of gangs indicates how many standard switches or receptacles the box can accommodate. For example, a 1-gang box is wide enough for a single switch or outlet, while a 2-gang box can hold two devices side by side.
The UK also uses the "n-Gang" terminology, but it has a slightly different meaning. UK plugs are typically larger and not stacked, so a 2-Gang box is wider than a 1-Gang box and has two sockets.
It's worth noting that the term "gang" can be confusing, as some electricians may use it interchangeably with the number of switches or outlets, while others may use it to refer specifically to the size of the box. This ambiguity can lead to misunderstandings, as highlighted by some users who noticed inconsistencies when working with 3 or 4 gang boxes.
To clarify, the "gang" terminology seems to be more closely related to the width of the box and the number of devices it can accommodate, rather than the exact number of switches or outlets. This interpretation aligns with the US construction practice of following a rule of one circuit per standard fixed box width.

In the UK, a 2-gang is wider than a 1-gang and has two sockets
In the UK, the term "gang" is used to refer to electrical boxes and sockets. In this context, a "gang" indicates the number of sockets or switches that can be accommodated within an electrical box. So, a 1-gang box is wide enough to fit one switch or socket, while a 2-gang box can accommodate two devices side by side.
The UK's 2-gang box is approximately 1.5 times wider than a 1-gang box, and it provides space for two sockets. This is in contrast to the US system, where a 2-gang box is twice as wide as a 1-gang and typically accommodates two stacked sockets.
It's worth noting that the term "gang" can also refer to the number of lighting circuits controlled by a switch. For example, a 1-gang switch controls a single lighting circuit, while a 2-gang switch allows you to control two separate lighting circuits.
The use of "gang" in electrical terminology can be a bit confusing, as it may refer to the physical size of the box, the number of switches or sockets, or even the number of lighting circuits controlled. The meaning of "gang" can vary depending on the country and specific electrical context.
In the UK, when specifically talking about sockets, a 2-gang is indeed wider than a 1-gang and provides space for two sockets, making it a useful option for homes or applications where multiple devices need to be plugged in simultaneously.

In the US, gang refers to the physical size of the circuit box
In the US, the term "gang" in electrical work refers to the physical size of a circuit box. Specifically, it indicates the width of the box and how many standard switches or receptacles it can accommodate. This terminology is different from that used in the UK, where a 2-gang box is roughly 1.5 times the width of a 1-gang box, while in the US, it is exactly double the width.
The use of "gang" to refer to the size of the box is believed to have originated from the standard US construction practice of allowing only one circuit per fixed box width. As a result, the term "gang" gradually took on the meaning of width rather than the number of circuits, as it does internationally.
A single gang, or 1-gang, box is wide enough to fit a single switch or outlet. A 2-gang box, being twice as wide, can accommodate two devices side by side. This pattern continues up to 10-gang boxes.
It is important to note that the term "gang" can also refer to the number of switches on a plate, as in the case of a "2-gang dimmer switch" or "2-way switch." In this context, a 2-gang switch allows for the control of two lighting circuits, and a 2-way switch refers to two switches controlling a single lighting circuit.

A 1-gang box is wide enough for a switch or duplex receptacle
The term "gang" is used to refer to the number of switches or outlets that can fit inside an electrical box. A 1-gang box, being the smallest, can fit one switch or duplex receptacle. In the US, the term "gang" refers to the physical size of the circuit box, with the number of gangs indicating how many standard switches or receptacles the box can accommodate.
In the US, a 2-gang box is twice the width of a 1-gang box, and a 3-gang box is three times the width of a 1-gang box. This linear increase in width with the number of gangs allows for multiple standard switches or receptacles to be fitted. For example, a 2-gang box can fit two switches or receptacles, and a 3-gang box can fit three.
The UK also uses the n-Gang terminology, but it has a slightly different meaning. UK plugs are bigger and are not usually stacked, so a 2-Gang is wider than a 1-gang and has two sockets. The number of gangs for switches refers to the number of switch buttons, not the physical size of the box. So, a 1-gang, 2-gang, and 3-gang switch may be the same size but have one, two, or three switch buttons, respectively.
It is important to note that the term "gang" can be confusing, especially when dealing with 3-gang or 4-gang boxes, as the sizes of the boxes might not seem to match the number of outlets that can fit inside them. Additionally, the term "stack switch" refers to having multiple switches in a single gang box, such as two bathroom switches stacked on top of each other, which is still considered a one-gang box with a specialized switch.
