        Mounting Block - Complete Guide of Electrical Mounting Blocks 

        Mounting blocks are used to install electrical switchgear, power points and audiovisual products. Essentially they allow these products to be installed on a surface and protect all the wiring inside the mounting block.

        What are the Benefits of Using a Mounting Block?

        Mounting blocks provide several benefits over other installation methods. Firstly, they allow products to be installed in a more versatile and efficient way instead of having them attached directly to the wall or ceiling. Secondly, they protect all of the wiring inside the mounting block, which minimises the chances of damage occurring during installation or during use. Finally, mounting blocks are often easier to move around than traditional electrical installations, making them ideal for use in tight spaces or areas that are difficult to access.

        How do Electrical Mounting Blocks work?

        Mounting blocks are essentially a platform that allows products to be installed on top of it. This platform is then attached to the wall or ceiling using screws, nails or adhesives, and the wiring inside the mounting block is protected from damage.

        Many of the mounting blocks have prefabricated knockouts to make it easier to install conduits straight into the block. Others have 20mm and/or 25mm entries on the side and rear.

        What are some common uses for electrical mounting blocks?

        Some common uses for electrical mounting blocks include installing switchgear, power points and audiovisual products in homes, businesses and offices. They can also be used to install CCTV systems, burglar alarms and other security systems.

        Please explain the different types of mounting blocks?

        Mounting blocks come in different depths, sizes, colours, and materials. Depending on the surface they will be installed onto, some have open backs, and others are fully enclosed. Let me go into more detail below.

        Standard Mounting Block

        A standard mounting block is used to surface mount standard size wall plates with 84mm centres, such as power points, light switches and other electrical accessories to walls or ceilings.
        The NLS 30048 mounting block and the Clipsal 449AB-VW are 34mm deep, allowing more room for cables to be housed or terminated. 
        These mounting blocks come complete with 2 x wall plate mounting screws.

        Solid Mounting Block

        Solid mounting blocks are used to surface mount standard size wall plates with 84mm centres, such as power points, light switches and other electrical accessories to walls or ceilings. The mounting block has a solid surface on the back so that it can also be mounted on metal walls like sheds. It protects the cables all around.
        The NLS 30318 mounting block is 38mm deep  (35mm internal), allowing more room for cables to be housed or terminated.
        The mounting block comes complete with 2 x wall plate mounting screws.
        There are 2 x 20mm conduit entries on the left and right sides of the mounting block.

        The Clipsal 238/25 electrical mounting block has 25mm entries.

        Shallow Mounting Block

        A shallow mounting block is used to mount power points, switches and other outlets onto solid walls. They are slim profile so that they do not protrude from the wall very far.
        These mounting blocks are great for mounting powerpoints onto timber. The internal fittings fit inside the profile of the block, saving the electrician a job cutting out the timber for installation.
