Frequently Asked Questions
Q: Where exactly should I install this fuse box in my inverter setup?
A: Install in positive (+) DC line between battery positive terminal and inverter positive input, as close to battery as practical (within 450mm maximum). Close battery placement protects maximum cable length from short circuit damage. Typical installation: battery positive terminal → fuse box → cable run to inverter → inverter positive input. Do not install in negative line—positive line fusing standard practice. Secure mounting preventing vibration loosening. Accessible location simplifying fuse inspection and replacement.
Q: How do I know what size fuse I need for my inverter?
A: Calculate based on inverter continuous power rating. Formula: Fuse rating (amps) = (Inverter watts ÷ 12V) × 1.25 safety margin. Examples: 500W inverter = (500W ÷ 12V) × 1.25 = 52A, use 60A-80A fuse; 1000W inverter = (1000W ÷ 12V) × 1.25 = 104A, use 100A-125A fuse; 1600W inverter = (1600W ÷ 12V) × 1.25 = 167A, use 150A-200A fuse; 2100W inverter = (2100W ÷ 12V) × 1.25 = 219A, use 200A-250A fuse. This 100A fuse suitable for inverters up to approximately 1200W. Oversized fuse provides inadequate protection, undersized fuse causes nuisance tripping.
Q: Can I use this instead of a circuit breaker for my inverter?
A: Yes, ANL fuse provides equivalent overcurrent protection to circuit breaker for inverter applications. Advantages of fuse: lower cost, simpler installation, no mechanical parts to fail. Advantages of circuit breaker: resettable without replacement part, manual disconnect capability, easier troubleshooting. Both provide adequate protection—choice depends on preference and budget. Fuse more common in budget installations, circuit breaker preferred in premium installations requiring manual disconnect capability.
Q: What happens when the fuse blows and how do I replace it?
A: Blown fuse interrupts power to inverter—inverter stops operating, connected appliances lose power. Fuse blows during short circuit conditions or sustained overload exceeding rating. To replace: disconnect battery negative terminal (safety), remove fuse box cover, remove blown fuse (visible broken element), install replacement 100A ANL fuse (Projecta IF-100), replace cover, reconnect battery. Investigate cause before restoring power—identify and repair short circuit or overload preventing repeated fuse operation. Carry spare fuses when touring enabling roadside repair.
Q: My inverter didn't come with a fuse—do I really need to add one?
A: Absolutely yes—fusing critical safety component preventing cable fire risk during short circuit conditions. Many inverters sold without external fusing expecting installer to provide appropriate protection. Australian electrical standards and insurance policies typically require proper overcurrent protection on high-current DC circuits. Without fusing, short circuit (damaged cable, inverter internal fault) causes cable to carry excessive current overheating insulation potentially causing vehicle fire. Proper fusing difference between safe installation and catastrophic failure. Always install appropriate fuse or circuit breaker between battery and inverter—never operate without overcurrent protection.
