Electrical Cable Sizes Australia • Direct & Ultimate

Whether you’re wiring a new shed, installing a ceiling fan, or just trying to understand what a sparky is talking about, electrical cable sizes in Australia can seem like a confusing alphabet soup. You’ll hear terms like 1.5mm, 2.5mm, 4mm , and letters like V-75, TPS, and V90 .

For the average Australian homeowner, remember that 1.5mm is for lights, 2.5mm is for power points, and larger sizes (4-6mm) are for big appliances. But if you're looking at a roll of cable and thinking of DIY-ing a new circuit, stop, put it down, and call a local sparky. The few hundred dollars you save isn't worth the risk of a house fire or a fatal shock. electrical cable sizes australia
