What's Included in Your Fridge Install

Every fridge install includes a dedicated circuit, the right cable gauge, and rated fusing. Clean wiring, no shortcuts.

Fridge Supply & Fit

We can supply the fridge or install your existing unit. We stock Bushman fridges and can source Engel and Dometic to order. All units come with full manufacturer warranty.

Dedicated Fridge Circuit

A fridge gets its own dedicated circuit run directly from the battery. No sharing with other accessories. Correct cable sizing for the run length and draw.

6mm Twin-Core Cable

6mm2 cable as standard for fridge runs. Sized to handle the start-up surge of a compressor fridge and deliver consistent voltage over long runs.

20A Inline Fuse & Breaker

An inline 20A fuse or circuit breaker fitted within 300mm of the battery. Protects the wiring from overcurrent and keeps your install compliant.

Fridge Slide or Drawer

Optional but strongly recommended. A quality fridge slide lets you pull the fridge fully out for easy access without lifting it. We install Decked and compatible slides to suit your tray or canopy.

Anderson Plug

A 50A Anderson plug gives you a clean external connection point. Use it to plug in the fridge lead from outside the vehicle, or to connect to a trailer or solar panel.

Cable Management

Every cable run neatly secured, labelled, and protected. No loose wiring rattling around the tray. Looks professional, stays put on corrugated roads.

Voltage Protection

Optional low-voltage cut-off or battery management relay to disconnect the fridge before your starter battery gets pulled too low. Keeps you starting every time.

Our Brand Choice

Why We Use Bushman Fridges

Bushman is an Australian-made brand built specifically for the Australian outback. Their DC compressor fridges run on a Secop Danfoss BD35 compressor, the same unit trusted in medical and scientific refrigeration. It's efficient, reliable, and handles Queensland heat in a way that cheaper compressors simply don't.

BUSHMAN AUTHORISED STOCKIST

The Bushman range includes the DC85-X (85L, ideal for 4WD canopies and the best-seller for solo and couples travel), the DC130-X (130L, popular for families and longer caravan trips), and the DC230-X (230L, suited to large caravans and long-term setups). All models are 12V/24V compatible, carry a 7-year manufacturer warranty, and are rated to Tropical T class (43°C ambient), essential for Queensland summers.

Common Questions

12V Fridge Installation FAQ

Honest answers to the questions we get asked before every job.

Every install is different depending on your fridge model and vehicle setup. Get in touch and we'll put together a straight quote based on exactly what you need.

A compressor fridge draws a short, high surge of current every time the compressor kicks in, often 3 to 5 times its normal running current. If it shares a circuit with lights, a 12V air compressor or camp lighting, or other accessories, that surge can cause voltage drops that affect other equipment and eventually stress the wiring. A dedicated run from the battery with its own fuse means the fridge gets clean, stable power and won't interfere with anything else.
For most 12V fridge installs we use 6mm2 twin-core cable. The right size depends on two things: the current draw of the fridge and the length of the cable run. A longer run needs thicker cable to prevent voltage drop that reduces the fridge's efficiency and can cause it to run longer to maintain temperature. We calculate the correct cable size for every install rather than guessing.
For a single person or couple doing weekends or short trips from a 4WD canopy or tray, the DC85-X (85L) is the right choice, it's the best seller for a reason. For families or longer caravan trips where you need fresh food and a freezer section, the DC130-X (130L) gives you the extra room. The DC230-X (230L) is for serious long-term setups in large caravans where you need correct fridge and freezer space. If you're not sure, call us and we'll work it out based on how you travel.
Technically yes, but not for long. A 12V fridge running off your starter battery overnight will flatten it. If you're day-tripping and only running the fridge while the engine is on, your alternator keeps the battery topped up and you'll be fine. For any overnight or multi-day use, you need a dual battery system to keep the fridge running without risking your starter battery. We can install both at the same time and give you a combined quote.

What Our Customers Say

★★★★★

Nathan installed 2 x 12 volts systems, one in our Motorhome and one in the trailer. Not only is the system fantastic and we never have to worry about our power, but he also fixed faults we had with our old system. The batteries have 7 years warranty, the upgrade to our panels keep the batteries topped up which really helps on cloudy and rainy days. We recommend Nathan to everyone, and he is so easy to deal with.

10/10 for everything! Nathan drove to woop woop to install our bushman fridge, new battery system & fans. Last week in 42 degrees our fridge was lovely and cold and the fans were a godsend! We will use Coast Custom 12 Volt for anything we need in our offgrid set up!
