Frequently Asked Questions
Q: Can I use a higher amp fuse than recommended? No. Using a fuse with a higher rating than required can result in overheating, fire risk, or appliance damage. Always use the correct rating for the device or circuit.
Q: How do I know which fuse I need?
Use a 3 Amp fuse for plug-connected appliances up to 700W.
Use a 5 Amp fuse in lighting circuits or as specified by the consumer unit label.
Q: Are these fuses reusable? No. Once a fuse has blown, it must be replaced. Never attempt to repair or bypass a fuse.
Q: Are these fuses suitable for modern circuit breakers? The 5 Amp cartridge fuses are suitable for older-style fuse boards. Modern installations typically use miniature circuit breakers (MCBs) or RCBOs, which function differently.
Q: How do I identify a blown fuse? In plug fuses, look for a visible break in the internal wire or signs of burning. In cartridge fuses, use a multimeter to test continuity.
