How to build a thin stud wall that supports wiring?

Question

Hi All,

Need to build a non-load-bearing stud wall which will contain AC/High-Voltage-DC Electrical power, trying to have it as thin as possible.

There are various timber sizes e.g. Timber Sizes: 70x35mm, 70x45mm, 90x35mm, or 90x45mm

What meets the electrical standards and framing standards?

Would Steel Plate/Nailer Plates (1.6mm thick) help, or some other metal shielding?

https://www.nsw.gov.au/housing-and-construction/compliance-and-regulation/electricians/electrical-standards-rules-and-notes/protection-of-cable-through-metallic-structures Does not say how thick the metal is?

Horizontal cable zones 150mm from the ceiling edges or from bottom of the floor into the wall.

Thanks

Welcome to the Bunnings Workshop community @damoa. It's fantastic to have you join us and many thanks for your question on creating a stud wall.

I can give some general guidance, but I’m not able to provide advice on electrical standards or compliance.

Because you’re dealing with high-voltage AC/DC cabling inside a stud wall, the final decision on framing size, shielding, and protection has to come from a qualified electrician. Electrical standards can be interpreted slightly differently by different professionals, and what one installer considers acceptable may not match another’s approach.

Since you’re aiming for a very thin wall, it’s especially important to run your plans past your electrician before building anything. They can confirm whether your proposed timber sizes, metal plates, and cable zones meet the relevant standards and provide a safe, compliant solution.

It’s definitely worth getting their input up front to avoid having to redo work or compromise safety.

Please let me know if you have any questions.
