Firstly disposal.

I have some memory that if you were to chuck away
an electrical appliance you should first cut the plug off.

Thats a stupid thing to do unless its dangerous if plugged in.

However a cut off moulded plug itself seems dodgy
as it could be plugged in and have a live connection.

Take the fuse out helps but kitkat wrapper.
So just put the whole thing in the electricals bin at the tip?

Particularly if its repairable and you choose not to repair
it yourself or dont know how to repair it yourself.
