Simple Reusable Fuse


Introduction: Simple Reusable Fuse

About: I just love electronics! Visit my youtube channel

In this instructable i will show how to make reusable fuse.

Step 1: Tools

Bad fuse
Drill bit

Step 2: Prepare Fuse

First you need to drill holes in fuse ends.

Step 3: Making Reusable Fuse

Strip wire.

Step 4:

Remove one thin wire from thick wire. If you put thicker wire then you will get higher amperage fuse.

Step 5:

Put that thin wire in fuse throught holes.

Step 6: You're Done.

Wrap ends of thin wire around fuse metal ends and you are ready to use it. With this wire from thick wire i get about 4A fuse.

    How can we figure out what size wire we need for the required amperage?

    By testing. Using power supply with adjustable current. You can measure wire thickness with micrometer very accurately.

    You can actually heat up caps and remove them
    Then just put wire inside and put caps back on
    Good idea would be to test wire first to see at what amperage does it burn out or buy replacing wires for fuses

    Yes i tested it and they work perfectly. Now i use only my reusable fuses for my power supply.

    Yes i tested it and now i use only reusable fuses for my power supply because they are so cheap.
