Metal backboxes, often referred to as metal flush-mounted back boxes, are electrical enclosures made of metal that are used for recessed or flush-mounted electrical outlets, switches, and other devices in wall installations. These backboxes provide a secure and robust housing for electrical components and are commonly used in various electrical installations. Here are key considerations regarding metal backboxes in the context of electrical installations regulated by BS 7671 (the 18th Edition of the Wiring Regulations) in the UK:

1. Material and Construction:

Metal backboxes are typically made from materials such as steel or aluminum. These materials provide durability and robustness, making them suitable for various applications, including commercial and industrial settings.
The construction of the box should provide rigidity and protection for the installed device and electrical connections.

2. Purpose of Metal Backboxes:

Metal backboxes serve as mounting and protective enclosures for electrical switches, sockets, dimmer switches, data outlets, and similar devices.
They are designed to be installed flush with the surface of walls, creating a clean and secure housing for electrical components.

3. Size and Configuration:

Metal backboxes come in various sizes and configurations to accommodate different types and quantities of electrical devices.
The choice of box size and configuration depends on the specific requirements of the installation and the number of devices to be accommodated.

4. Knockouts and Cable Entries:

Metal backboxes typically have multiple knockout or cable entry points to allow electrical cables and conduit to enter the enclosure.
Knockouts should be sealed to prevent the ingress of dust, insulation material, or other contaminants.

5. Depth of Box:

The depth of the metal backbox should be selected to accommodate the specific device and the depth of the wall cavity. Standard depths are available to suit most applications.

6. Mounting Options:

Metal backboxes can be installed either horizontally or vertically, depending on the orientation of the electrical device.
Proper alignment and mounting are crucial to ensure the device fits securely and is level with the wall surface.

7. Accessibility:

Metal backboxes should be accessible for installation, maintenance, and future modifications. Removable covers or faceplates provide access to the device and connections.

8. Compliance with Standards:

Metal backboxes should meet the relevant standards and regulations outlined in BS 7671 and other applicable electrical standards to ensure safety and performance.

9. Labeling and Identification: – Enclosures may require labeling or marking to identify circuits, devices, or equipment within the enclosure.

Metal backboxes are commonly used in commercial, industrial, and residential electrical installations where robustness and durability are required. Proper installation and the use of appropriate boxes ensure the safety, reliability, and compliance of electrical systems. Electricians and technicians should follow the guidelines and regulations set forth in BS 7671 and other relevant standards when working with metal backboxes.
