What appliances do not need a fuse?

Aga cooker. Gas ascots. My electric toothbrush doesn't have a fuse, and niether does the charging station (that I know of) the 2 pin plug goes into an atapter
which does have a 3 amp fuse in it IIRC, same as with my shaver.

Are you sure the charging station doesn't have some form of internal
fuse?

I assume it does but we are talking about appliancies where the fuse can be replaced. AFAIK my toothbrush does NOT contain a fuse.
The charging station should have a fuse as that is the ONLY section connected to the mains supply and in accordence with UK electrical safety must contain some sort of fuse, whether it is current or temperature driven,
resetable or not I don't know, but it is most likely a non-servicable pat the
a user shouldn't replace.

The statement was what appliances NEED a fuse and not whether they have one or not, there is a differnce there too.


If an appliance uses an "inherently short-circuit proof" mains transformer
for its power supply, it does not need any kind of fuse - not even an
over-temperature fuse inside the transformer.
I have designed such products and had them successfully tested by Intertek.
