AUSTRALIAN MADE CABLE

Here at The 12 Volt Shop, we only supply high-quality Australian Made Cables manufactured by industry leaders including Tycab (Tyree Cables), Key Tubing Electrical, Elcon Cables, and Austech.

Selecting the correct cable thickness is critical to system safety and performance. A common misconception is that short cable runs allow you to exceed a cable's continuous current rating. While short runs reduce resistance and voltage drop, they do not change the physical thermal capacity of the copper conductor—overloading a short cable generates excessive heat, creating a serious fire hazard.

Real-world cable selection must account for JASO D609 de-rating factors, including conductor bundling (e.g., positive and negative cables touching) and elevated ambient temperatures (such as inside engine bays, canopies, or battery enclosures).

To calculate voltage drop and minimum wire gauge for specific run lengths, you can download the free Victron Toolkit App or refer to our detailed technical guide below:

* AMP RATING: Based on JASO D609 standards in free air at 30°C ambient. Real-world continuous capacity decreases significantly when bundled or operated in heated compartments.

NOTE: Roll quantities offer lower per-metre costs and reduced freight rates compared to purchasing cut lengths per metre.
