The Complete Guide to Box Trailer Wiring Diagrams in Australia

Towing a trailer is an important task that is sometimes essential to everyday life. Whether you're transporting livestock or bringing home holiday souvenirs, it's important to have a proper and safe wiring system for your trailer. In this article, we will explore the wiring diagrams for box trailers in Australia, helping you understand the importance of the Electrical Wiring Regulations (EWR) and giving you tips on how to safely wire up a box trailer.

Understanding the Electrical Wiring Regulations (EWR)

The EWR sets out the standards for wiring and electrical systems in Australia, ensuring safety for everyone involved. In terms of box trailers, there are certain guidelines set in place for ensuring the wiring is done correctly. The National Standard for Light Vehicle Construction and Modification (NSLVCM) sets the standards for passenger-carrying vehicles, while the Australian Design Rules (ADRs) set standards for the wiring of goods or utility trailers.

Designing Your Own Wiring Diagram

When designing your own wiring diagram, you will need to consider the components of your trailer and the overall length of the wiring harness. The trailer will generally include lighting and braking components, and the wiring harness will be of a specific length to ensure it is able to reach all the components. You may also need to include power sources such as an auxiliary battery to help run the lights when the car is not running.

Understanding the Different Types of Wiring

The type of wiring used for box trailers in Australia can vary, and it’s important to have a thorough understanding of these types. There are two primary types of wiring: Assembled wiring and bulk wiring. Assembled wiring consists of individual wires which are soldered together, while bulk wiring consists of pre-wired cables in specific lengths. Each type of wiring has its advantages and disadvantages, so you should always consult an electrician when wiring up a trailer.

Installing the Wiring Harness

Once you have designed and purchased the appropriate wiring components, you will then need to install the wiring harness. This process can be done either by yourself or by a professional, however, it is recommended to get a professional to do the job for safety reasons. When installing the wiring, make sure to use waterproof connectors and cover any exposed wires with heat shrink tubing to prevent any short-circuits from occurring.
