FAQs
Can I use a 30A fuse instead of a 20A fuse?
No. You must always use the exact amperage rating specified for your circuit to prevent overheating and fire risks.
How do I know if the fuse has blown?
You can use a multimeter to check for continuity across the fuse. If the multimeter does not beep or show zero resistance, the fuse is blown.
Is this fuse reusable?
No. Cartridge fuses are single-use protection devices and must be discarded after they have blown.
What happens if I use a lower amperage fuse?
The fuse will likely blow frequently under normal operating loads because it cannot handle the current intended for the circuit.
Are Wylex fuses universal?
While they fit many standard carriers, always ensure the physical length and diameter match your original fuse to ensure a safe electrical connection.
Troubleshooting
Fuse blows immediately after replacement
There is likely a short circuit or an overloaded appliance on the line. Unplug all devices on the affected circuit and have a qualified electrician test the wiring.
Device still has no power after replacing the fuse
Check that the fuse is fully seated in the carrier clips. Verify that the fuse carrier itself is pushed completely into the consumer unit base.

Setup, Compatibility & Care
Before installing, ensure the main power to the circuit is switched off. Verify that the fuse carrier is compatible with the physical dimensions of the Wylex cartridge. When inserting the new fuse, ensure it is seated firmly in the clips of the carrier. If the fuse clip feels loose or shows signs of oxidation, gently clean the contacts or seek professional advice to ensure a secure connection. Do not attempt to bypass or 'bridge' the fuse with wire, as this creates a significant fire hazard.
