I have chosen not to participate in this thread because I've said all that I have to say on the subject in numerous fuse-related threads in the past.
However I just want to state a point of information: Posts that have been made by at least three different members appear to imply that the purpose of an AC mains fuse in a component is to provide protection against surges in the incoming AC. While it is possible that an AC mains fuse might do that under some circumstances, that is not its intended purpose. Its intended purpose is to blow if a fault within the component causes it to draw excessive AC current. Thereby preventing **additional** damage to the component that may otherwise occur, as well as preventing the possibility of the component overheating or even bursting into flames as a result of the excessive current being drawn.
