Fitting a fuse depends on whether it is a re-wireable or a cartridge type.
Replacing a blown fuse is a common task to restore power to a circuit. The method varies slightly depending on the style of the fuse holder you have.
Replacing a Re-wireable Fuse
If your fuse box uses older, re-wireable fuses, follow these steps as described in the reference:
- First, ensure the power to the circuit is off.
- Pull out the fuse holder to check if it is the blown one.
- If it is a re-wireable fuse, remove any remaining old wire.
- Feed new fuse wire through the holder.
- Wrap the wire around the retaining screws at each end.
- Screw up tightly at both ends to secure the wire and ensure a good connection.
- Insert the fuse holder back into its slot.
It is crucial to use the correct amp-rated fuse wire for the specific circuit to prevent damage or fire hazards.
Replacing a Cartridge Fuse
Modern fuse boxes often use cartridge fuses. The process for replacing these is simpler:
- Again, ensure the power to the circuit is switched off.
- Pull out the fuse holder to check which fuse has blown.
- If it is a cartridge fuse, take out the old cartridge.
- Fit a new cartridge into the holding clips.
- Push the fuse holder back into its position in the fuse box.
Cartridge fuses are designed to be non-replaceable internally; you simply swap the entire cartridge unit. Always use a new cartridge fuse with the exact same amperage rating as the old one.
Choosing the correct type and rating of fuse is essential for safety and proper circuit protection.
