3.0mm White Electrical Cable – 500 Metre Roll

The Cable That Keeps Your Build Moving

Every quality caravan, camper trailer, and 12V installation starts with quality cable. Undersized, poor-quality wiring is one of the most common causes of electrical faults, voltage drop, overheating, and even electrical fires in touring rigs — and it's entirely preventable when you start with the right cable from the beginning. The 3.0mm White Electrical Cable 500m Roll gives professional builders, auto electricians, and dedicated DIY installers the quality and quantity needed to do the job properly, from first circuit to last.

3.0mm — the versatile workhorse of 12V installations. At 3.0mm, this cable sits in the sweet spot of the caravan and camper wiring world — substantial enough to carry meaningful current loads across the circuit runs found in modern touring rigs, while remaining flexible and manageable enough for clean installation through conduit, cable clips, and tight routing paths. It's one of the most commonly specified cable sizes for 12V lighting circuits, accessory feeds, switch wiring, and general purpose caravan and camper trailer wiring.

500 metres — the professional builder's choice. Half a kilometre of cable on a single roll is the smart buy for anyone serious about their electrical work. Whether you're building a new caravan from the ground up, rewiring an existing rig from scratch, stocking a workshop bench, or running cable across a large off-grid property setup, 500 metres means you have everything you need without the frustration and cost of running out halfway through a job. For auto electricians and caravan manufacturers, bulk buying also delivers significant cost savings over purchasing shorter lengths repeatedly.

White colour — clean, professional & easy to identify. The white outer sheath serves two important purposes. First, it gives your installation a clean, professional appearance — white cable against white caravan interior walls and ceiling liners virtually disappears for a factory-finish look. Second, white is widely used as a standard colour code in 12V and automotive wiring for specific circuit types, making identification and fault-finding faster and more straightforward for anyone working on the installation down the track.

Flexible construction — routes cleanly through any space. Caravan and camper trailer wiring rarely runs in straight lines. Cable needs to navigate through wall cavities, around corners, through grommets, along chassis rails, and into tight junction boxes and switch panels. This cable's flexible construction makes it easy to route cleanly through all of these paths without kinking, cracking, or fatiguing — essential for a long-lasting, reliable installation that holds up to the constant movement and vibration of life on the road.

Durable outer sheath — built for the long haul. The robust outer insulation is designed to resist the abrasion, heat, UV exposure, and chemical contact that wiring encounters in automotive and caravan environments. Whether it's running through a sun-baked roof cavity, along a hot chassis rail, or through an engine-adjacent space, this cable's sheath maintains its integrity and insulating properties across the full range of conditions Australian touring rigs encounter.

Suitable for a wide range of 12V applications. From lighting circuits and accessory feeds to switch wiring, solar installations, and general purpose 12V distribution — 3.0mm cable covers an enormous range of caravan and camper wiring applications. Having 500 metres on hand means you have the right cable ready for every circuit in the build, every repair job, and every future upgrade your rig might need.

The smart buy for workshops, builders & serious DIYers. For caravan manufacturers, auto electricians, and fabrication workshops, buying a 500m roll is simply the most efficient and cost-effective way to keep quality cable on hand. For the dedicated DIY caravan owner undertaking a full rewire or major electrical upgrade, it's the one purchase that ensures you'll never have to stop work and make a trip to the supplier for more cable.
