Common in some American-influenced builds (e.g., Jayco).
The 12-volt wiring colour code in Australia is simple: , with strict avoidance of green/yellow for anything but earth. While other colours appear in vehicle looms and trailer plugs, they are for signalling, not main power. 12 Volt Wiring Colour Codes Australia
In Australia, 12-volt wiring is governed by the (Electrical Installations – Transportable structures and vehicles) and general wiring rules outlined in AS/NZS 3000 (the "Wiring Rules"). However, many users confuse 240V mains colour codes with low-voltage DC codes. This article will clarify the essential standards, common practices, and critical safety notes for 12V DC wiring in Australia. Common in some American-influenced builds (e
These colour codes are widely accepted and used across Australia, but it's essential to note that there may be variations depending on the specific application or industry. In Australia, 12-volt wiring is governed by the
Often used for specific triggers, like high-beam feeds for driving lights or trailer brake outputs. Caravan "House" Electrics (Internal)
If you accidentally use brown and blue for 12V DC, future workers may mistakenly treat it as 240V and get a lethal shock. Even if it's only 12V, the visual cue can lead to dangerous assumptions in mixed-voltage enclosures.
