How do my TV Wall Provisions (conduits) work?
The blank wall plates located in your audio visual area cover the entry points to conduits installed inside the wall.
These conduits are typically 25mm external diameter (approximately 21–23mm internal diameter) and are designed to conceal interconnecting cables between your wall-mounted TV and your audio visual equipment below (such as a cabinet or rack).
How Do I Access the Conduits?
To access the conduit:
The blank wall plate can be completely removed, or
Your TV installer can cut an opening through the cover plate using a hole saw.
This allows cables to be fed through the wall cavity for a clean, concealed installation.
Important: Power Cable Considerations
Due to the internal size limitations of the conduit:
TV power cables with large IEC 3-pin plugs, or fixed (non-removable) power leads, may require modification before being fed through the conduit.
Any modification of a power cable must be carried out by a licensed electrician or suitably licensed technician, in accordance with Australian regulations.
Some TVs are supplied with smaller “figure 8” style power cables, which typically do not require modification.
Choosing the Right Cables
When purchasing cables or arranging a TV installation, it is very important to consider the internal conduit size (approximately 21mm).
HDMI cables with large head connectors are the most common cause of installation issues. Oversized connectors may not fit through the conduit, resulting in visible cables running down the wall — which defeats the purpose of the wall provisions.
We recommend:
Using slim HDMI cables
Ensuring the HDMI head connector is no larger than 20mm wide
HDMI cables are available in various sizes, so selecting the correct type in advance will help ensure a clean and professional result.
A Note on Cavity Walls
For cavity walls, TV Wall Provisions may be installed using:
25mm conduits, or
Wall boxes with draw wires only
The installation method is determined by the on-site installers based on wall construction and site conditions.
If you are unsure which cables are suitable, or you would like assistance with supply or installation, we strongly recommend contacting your original Intelligent Home sales consultant. Our team can provide advice, supply compliant cables, or arrange professional TV installation as required.
