Leo traced the line. "It says... 24 Amps."

For the licensed electrician, the cable size chart is a legal document. For the homeowner, it’s a warning: never downsize a cable to save $20 . In Australia’s harsh climate, the copper is cheap—the fire is expensive.

Leo’s stomach dropped. He realized his mistake. He had relied on "rules of thumb" instead of the cold, hard data of the Australian Standards (AS/NZS 3008).

While the physical (often found in the back of the AS/NZS 3000 Wiring Rules ) is mandatory for every licensed sparky, most tradies now use mobile apps that reference AS/NZS 3008. However, the app is only as good as the user’s inputs—you must know the installation method (A1, B1, C, etc.) to get the right answer.
