Why don’t use the Wrong Fuse Amperage?

Fuses protect your electrical system. They are there to keep it safe against

  • Overloads circuits and
  • Short circuits.

However, utilizing the wrong amperage might lead to major problems:

Using a Higher Amperage Fuse

  • Allows excessive current to flow.
  • Can harm cables, sensors, and possibly causes fire.
  • The circuit is no longer effectively protected.

Using a Lower Amperage Fuse

  • Blows easily, even under typical load.
  • Causes unpleasant faults and frequent replacements.
  • This makes the circuit unreliable & unstable.

How to Detect a Bad Fuse?

Here’s how to see if a fuse has blown.

Step 1: Visual Inspection

  • Remove the fuse from the fusebox.
  • Check out the metal strip inside.
  • If the fuse is burned or damaged, it is defective.

Step 2: Use a Multimeter

  • Switch the multimeter to continuous mode.
  • Touch the probes to both ends of the fuse.
  • Beep (or) low reading indicates a good fuse.
  • No sound or continuity indicates a blown fuse.
  • Replace blown fuses with the same amperage rating (Ex: 15A fuse with another 15A).
