Changing a fuse in a plug is a straightforward process that restores power to your appliance when the original fuse has blown, often indicated by the appliance not working.
It essentially involves opening the plug, replacing the old fuse with a new one of the correct rating, and closing the plug back up.
Understanding Plug Fuses
Household appliance plugs in many regions use cartridge fuses to protect the appliance and wiring from overcurrent. These fuses typically contain a wire that melts and breaks the circuit if too much current flows through it.
Fuses come in different ampere (amp) ratings, such as 3 amps and 5 amps, among others. The correct rating depends on the appliance's power consumption. Using a fuse with too high a rating can be a fire hazard, while one too low will simply blow easily. The required fuse rating is often indicated on the appliance or in its manual. According to the reference, common ratings are 3 amps and 5 amps depending on their purpose.
Step-by-Step Guide to Changing a Plug Fuse
Here’s how to safely change a fuse in a plug:
Step 1: Safety First
- Unplug the appliance: Always ensure the plug is completely disconnected from the wall socket before you begin.
- Gather tools: You'll typically need a small flat-head or Philips screwdriver, depending on the plug's design.
Step 2: Open the Plug
- Look for a small screw (or sometimes two) on the back of the plug cover.
- Use the appropriate screwdriver to loosen and remove the screw(s). Keep the screw(s) in a safe place so you don't lose them.
- Carefully lift off the plug cover. This will expose the wiring terminals and the fuse holder inside.
Step 3: Locate and Remove the Old Fuse
- The fuse is usually a small ceramic or glass tube, often located near the live pin (the top or right pin).
- Gently pry the old fuse out of its clips or holder. It may just lift out.
Step 4: Identify the Correct Replacement Fuse
- Check the ampere rating of the old fuse. This is usually printed on the metal cap of the fuse (e.g., 3A, 5A, 13A).
- Ensure your new fuse has the exact same rating as the old one. Remember fuses can be 3 amps and 5 amps depending on their purpose.
Step 5: Insert the New Fuse
- Take the new fuse of the correct rating.
- Place the new fuse into the empty clips or holder inside the plug.
- Based on the reference, you will Click it into that top terminal. Click it into that one to secure it correctly within the plug's holder or connection points.
Step 6: Close the Plug
- Align the plug cover back onto the plug body, making sure the wires are not pinched.
- Replace the screw(s) you removed earlier.
- Tighten the screw(s) firmly, but do not overtighten, as this can crack the plastic.
- Once the cover is back on and secured, you're good to put the cover back and the job is complete.
Step 7: Test the Appliance
- Carefully plug the appliance back into the wall socket.
- Turn on the appliance to check if it now works.
Changing a fuse is a simple maintenance task that can get your appliance working again. Always ensure you use the correct fuse rating for safety.
