Introduction: Simple Reusable Fuse

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

Step 1: Tools

Scissors
Bad fuse
Wire
Drill
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

Interesting idea. Have you tested this, and does it work?

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.
