Fuse changing

Tips to change your fuse.

Step 1: Plug fuse

  • Unscrew the retaining screw on the underside of the plug between the pins. Remove the cover and lift out the fuse.
  • Check the rating of the fuse and if adapted to the appliance. As a general rule, use a 3 amp fuse for appliances up to 720 watts and a 13 amp for appliances from 720 watts to 3000 watts.
  • Fit the replacement fuse in the holder, check that all the conductors are securely held in their terminals with no stray strands of wire, check that the flex is held firmly in its clamp and replace the cover with its retaining screw.

Step 2: Fuseboard

When a fuse ‘blows’ on one of the circuits in your house, it is an indication something is wrong. Make sure the main switch is off before doing anything.

Identify the type of fuse fitted. Fuses are labelled to show the rating in amps so you should be able to narrow down the possibilities by checking fuses of the appropriate rating for the circuit which has failed.

Step 3: Check if any overloading of circuits

  • If you suspect overloading of the circuit, make sure the main switch is still off at the consumer unit and remove the fuse. Unplug all appliances on the circuit which has blown. If the problem was overloading, once you have replaced the fuse or reset the Miniature Circuit Breakers (MCB), the circuit should work. Otherwise, further investigation is needed.
  • Check each fitting on the circuit by removing its cover to see if any of the wires have become loose or are damaged in any way. If this is the case, repair before refitting the covers of all fittings.
