How to change a fuse on a plug socket ?
For a standard plug you will need a screwdriver (usually a flat
headed screwdriver but will depend on the screws in that particular
plug – take a look at the base).
1) In an anti-clockwise direction, loosen the screw(s) – typically
this type of plug will have a larger central screw that holds the
cases halves together; that’s the one to go for. You may not need
to remove all the screws completely as the back of the plug should
come away following a few turns of the screws.
2)Open the case and keep the back and the screw in a safe place for
reinstating later.
3)Pull the fuse out, you will find the fuse within two metal
holders inside the plug, sometimes these can be tight and need to
be prised out, don’t worry if one of the pins lifts out with it
initially – this just slides back through the case once the fuse is
removed.
4)Replace the old fuse with a new fuse (making sure it’s like for
like or that you really understand why it’s changing if it is).
5)It’s often worth just checking the terminals (the small screws
that hold the cables in the plug) are tight at this point – a loose
connection can cause overheating and an increase in current which
may be why the fuse blew initially). Just try to tighten them with
(usually) a small flat blade screwdriver to make sure they are nice
and tight.
6)Return the lid of the plug and screw firmly. When secure there
should be no movement from the metal pins that go into the wall
socket.
7)If the fuse blows again, there may be an electrical fault not
associated with the fuse. In this instance, we would recommend an
electrician to carry out an electrical safety inspection to check
the product.
Description
Developed by UCHI for the automotive industry, MEDIUM AUTO BLADE
fuse has become the original equipment circuit protection standard
for foreign and domestic automobiles and trucks. Readily
identifiable and easily replaced, this fuse can be specified for a
variety of low voltage electronic applications.
