In electrical terms, a gang is a term used to describe a group of switches or outlets that are connected to a single circuit and controlled by the same mechanism. The number of switches or outlets in a gang is indicated by a number followed by the word gang, such as one-gang, two-gang, or three-gang. For example, a one-gang box is a typical outlet or switch with a single device, while a two-gang box has two devices side by side. Gangs are commonly used in residential settings to control lighting fixtures from multiple locations, such as in hallways or rooms with multiple entrances.

What You'll Learn
Gangs refer to the number of switches on a faceplate
In electrical terms, a gang refers to the number of switches or devices on a faceplate, with each switch controlling the same electrical load (light or device). The most common types of gang switches are 1-gang, 2-gang, and 3-gang, but they can go up to 10 gangs. A 1-gang box, for instance, is wide enough to fit only one switch or outlet, while a 2-gang box holds two devices side by side. A 3-gang switch includes three switches in a single unit or frame, allowing control of the same electrical load from three different locations.
Gangs are also used to describe light or groups of lights on a single circuit. For example, a standard ceiling lamp is a gang, but a cluster of LEDs in a bathroom can also be considered a gang. In this context, a 2-way, 2-gang switch refers to having two switches that control the same light, often used in staircases or large rooms.
It is important to distinguish between the number of gangs and the number of ways. While the gang refers to the number of switches, the way describes the wiring setup on the back of the switch. For example, a 1-way switch is a typical on/off switch that controls a single light. An intermediate switch, on the other hand, allows control of the lights from three different places and would be considered a 3-way switch.
When working with electrical sockets and switches, it is crucial to prioritize safety. Always ensure that the power is turned off and the circuit is isolated before proceeding with any electrical work. If you have any doubts, it is recommended to consult a professional electrician.
While changing a light switch faceplate is a task that can be done without the assistance of a qualified electrician, it is important to understand the different types of switches and their functions before proceeding with any electrical work. Knowing the specific type of switch you are working with will help ensure that you replace it with a like-for-like alternative.

1-gang boxes are for a single outlet or switch
In electrical terms, a gang is a way of referring to a light or a group of lights on a single circuit. A 1-gang box, therefore, is a regular outlet or switch with a single device. These boxes are generally about 2 inches wide by 4 inches tall, and their depths range from 1-1/2 inches to 3-1/2 inches. They can be metallic or non-metallic, and some have built-in cable clamps for securing NM cables.
A 1-gang box is used for a single light fixture switch or outlet receptacle. It is important to note that electrical boxes encase wire connections to protect them from short circuits and are vital for fire safety. They are used for various applications, including receptacles, ceiling fans, and outside outlets.
When installing a 1-gang box, it is essential to use a cover to enclose the front of the box. Leaving an electrical box uncovered is unsafe and often illegal. Solid or blank covers have no holes and are used with junction boxes or for enclosing unused boxes. Covers for specific types of boxes, such as 4-inch square boxes, may have special cutouts to accommodate switches or outlets.
It is worth noting that there are different types of electrical boxes available, including square boxes, which offer more interior space due to their square corners. Additionally, there are old-work boxes, which are designed to be installed flush with the drywall, and junction boxes, commonly used in commercial construction but also found in residential settings.
In summary, a 1-gang box is designed for a single outlet or switch, and it is important to select the appropriate type of box and cover to ensure a safe and functional electrical installation.

2-gang boxes are for two devices side by side
In electrical terms, a gang refers to the number of yolks or devices that can fit into an electrical box. A single gang box, for instance, is only wide enough to fit one switch or outlet. A 2-gang box, on the other hand, is designed to hold two devices side by side.
In a 2-gang box, you can have two plugs set next to each other sideways, or a plug and a switch. This setup is common in areas with multiple controls for multiple lights, such as entryways and kitchens. For instance, in a bathroom, you can have a 2-gang switch where one button controls the ceiling lights and the other controls the mirror lights.
It is important to note that the term "gang" can be confusing, especially when it comes to 3-gang and 4-gang boxes. While a 3-gang box may suggest that it can fit three devices, the sizes of these boxes may not always match the number of outlets that can fit into them. Similarly, a 4-gang box may be referred to as having four outlet ports, but it is essentially a 2-gang box with two plugs or outlets.
When working with electrical boxes, it is crucial to consider factors such as wiring, wall plate coverage, and box fill to avoid errors and ensure a proper fit.

3-gang boxes are for three switches in a single unit
In electrical terms, a gang is a way of saying 'light or groups of lights on a single circuit'. For instance, a standard ceiling lamp is a 'gang', but a cluster of LEDs in your bathroom can also be considered a gang.
A 3-gang box, therefore, refers to a single unit with three switches. These switches can operate three sets of lights. A 3-gang box can be rotated 90 degrees if there is not enough room for three switches side-by-side.
A 3-gang box can be used to control a variety of lights, such as floodlights and deck lights. They are also commonly used in large rooms with multiple entrances, hallways and stairways.
It is important to note that the term 'gang' can be confusing as the sizes of the boxes do not always match the number of outlets that can fit into them, especially with 3-gang and 4-gang boxes.

Gangs are an electrician's term for a group of lights on a single circuit
Gangs refer to the number of switches or outlets grouped together in a single unit, box, or frame. The term is used by electricians to describe a group of lights on a single circuit. For example, a one-gang box contains a single outlet or switch with one device, while a two-gang box contains two devices side by side. Similarly, a three-gang or four-gang box would contain three or four devices in a row, respectively. These boxes are commonly used in areas with multiple controls for multiple lights, such as entryways and kitchens.
In the context of switches, a gang describes the number of switches on a plate or faceplate. Each switch within a gang setup can control the same electrical load (light or device) and can be operated independently from different locations. For instance, a one-gang switch is a single switch in a single unit that controls one electrical load, such as a single light fixture, from a single location. On the other hand, a two-gang switch consists of two switches in a single unit, both controlling the same electrical load, which can be operated from two different locations.
Gangs are also relevant when discussing ways, which refer to the wiring setup of a switch. A one-way switch is a typical on/off switch where a single switch controls a single light. A two-way switch means there is another switch controlling the same light, often used on staircases or in large rooms. Additionally, intermediate switches are used when control of the lights is required from three different places.
It is important to note that the terminology surrounding gangs and ways can be confusing, and manufacturers often use different naming conventions for their products. When working with electrical systems, it is crucial to prioritize safety and consult a professional if there is any doubt.
Ganged lights are a common feature in many electrical systems, allowing for convenient control of multiple lights from a single circuit. This knowledge of gangs can help homeowners and electricians alike understand and work with their lighting setups effectively.
