Frequently Asked Questions (FAQs)
What are low voltage fuses used for in caravans and RVs?
Low voltage fuses are used to protect 12V and 24V circuits in caravans and RVs from overcurrent and short circuits. They’re commonly installed in lighting systems, fridges, pumps, and power outlets to prevent component damage or electrical fires.
What's the difference between blade fuses and circuit breakers?
Blade fuses are single-use components that melt when current exceeds their rating, while circuit breakers are resettable protection devices that automatically (or manually) trip and reset. Circuit breakers are ideal for circuits you want to restore without replacing components, while fuses are cost-effective and easy to replace.
How do I choose the correct fuse size for my RV setup?
Fuse size should match the maximum expected current of the circuit it's protecting. Always use the lowest rated fuse that safely supports your device’s current draw, and consider the wire gauge and length. Overfusing can lead to overheating and damage. If in doubt, consult an auto electrician.
Can I use MAXI fuses in place of standard blade fuses?
MAXI blade fuses are designed for higher current applications (typically 30A and above) and have a larger footprint than standard blade fuses. They are not interchangeable with standard ATO/ATC fuses and require appropriately sized fuse holders.
Are auto reset circuit breakers safe to use in mobile applications?
Yes, auto reset circuit breakers are ideal for non-critical 12V circuits in caravans and boats where convenience is important. They automatically reconnect after tripping, reducing downtime. However, for critical systems, manual reset types are recommended to ensure safe inspection before reset.
Can I install these fuses and breakers myself?
If you're confident with 12V systems and follow wiring best practices, many users successfully install blade fuses and holders themselves. For complex installs, especially those involving circuit breakers or fuse blocks, we recommend a licensed auto electrician to ensure compliance with Australian wiring standards.
What fuse colours correspond to what amperage?
Blade fuses follow an international colour code:
Black (1A), Grey (2A), Violet (3A), Pink (4A), Tan (5A), Brown (7.5A), Red (10A), Blue (15A), Yellow (20A), Natural/Clear (25A), Green (30A), Purple (35A), Orange (40A).
Always check both the colour and the printed rating.
What standards apply to automotive fuses and breakers in Australia?
While there is no single universal standard for all low voltage RV components, most products are designed to meet international norms like ISO 8820 (for blade fuses). In Australia, compliance with the Wiring Rules (AS/NZS 3001 for recreational vehicles) is critical, especially for 12V and 240V systems working in tandem.
