A metal back box is a metal enclosure used to house electrical sockets, switches, and other electrical fittings. They are installed within walls and provide a secure and stable mounting for the electrical components.
Common sizes for metal back boxes in the UK include:
Yes, metal back boxes must be earthed to ensure electrical safety. They typically have an earth terminal to connect the earth wire from the electrical circuit.
Metal Back Boxes: More robust, provide better protection against fire, and are often required by building regulations for certain installations.
Plastic Back Boxes: Easier to install in drywall or plasterboard, non-conductive, and do not require earthing.
Knockouts are pre-scored sections on the back or sides of a metal back box that can be easily removed to allow for cable entry. They are designed to be punched out using a hammer and screwdriver or pliers.
