Electrical systems are the backbone of modern camper van living—powering everything from your fridge and lights to solar setups and phone chargers. But poorly designed or maintained systems can pose serious risks.
At Vanish Campers Brisbane and Sunshine Coast, we’ve seen firsthand how common electrical mistakes can turn into costly—or even dangerous—problems. Whether you’re a DIY builder or new van owner, here are 7 electrical safety mistakes you should avoid to keep your camper van safe and reliable.
1. Using Undersized Wiring
Too many DIY van builds use wires that are too small for the current they carry. This not only causes voltage drops and poor performance—it can overheat wires and start fires.
Tip:
Always use the correct wire gauge based on current and wire length. Use online calculators or consult a professional if unsure.
2. Skipping Fuses or Circuit Breakers
Every major component in your van’s electrical system should be fused or protected by a circuit breaker. Skipping this step can result in catastrophic electrical fires if a short circuit occurs.
Tip:
Install fuses as close to the power source as possible. Every battery, inverter, solar charge controller, and load should have appropriate protection.
3. Improper Battery Ventilation
If you’re using lead-acid or AGM batteries, they emit gases during charging. Poor ventilation can lead to dangerous hydrogen gas buildup—which is highly flammable.
Tip:
Mount batteries in a well-ventilated compartment, or opt for lithium batteries, which are safer and more compact.
4. Neglecting Earth Bonding (Grounding)
Failing to properly ground your camper van electrical system can result in shocks or damage to your gear. It’s one of the most overlooked safety measures in van builds.
Tip:
Connect your negative bus bar to your vehicle chassis. Make sure all 240V systems are grounded by a qualified electrician.
5. Mixing Incompatible Components
Combining electrical parts without checking voltage and amperage compatibility is a recipe for system failure—or worse.
Tip:
Match your components: solar charge controllers, inverters, and batteries must be rated for the same system voltage (usually 12V or 24V).

6. Overloading the System
Adding new gadgets or appliances without checking your battery and inverter limits can result in tripped breakers, dead batteries, or melted wiring.
Tip:
Calculate your total expected wattage draw and make sure your system is rated to handle it. Overspec your inverter and battery bank if you plan to grow.
7. DIY 240V Wiring Without Certification
In Australia, it is illegal and dangerous to install 240V (mains power) systems without a licensed electrician. DIY mains wiring puts you and others at serious risk of shock or fire.
Never DIY:
-
240V sockets
-
Shore power hookups
-
Hardwired appliances
Do This Instead:
Always hire a certified auto electrician or RV specialist. Vanish Campers Brisbane & Sunshine Coast can help ensure your high-voltage setup is compliant and safe.
