Several questions about the circuit protection that using linear power supplies
#4
My two cents, probably worth less.

If anything more than a quick blow fuse significantly increased safety then I'd expect to see that in ordinary commercial designs.

A small transformer is going to saturate so what goes in will be limited at the output.

Switching/fusing the neutral is a very bad idea unless it's a mechanically linked double pole swich. The thing will look dead but isn't.

The fuse needs to after the switch not before. So you can switch off and you are not changing a live fuse.

How do you know that the diodes aren't zapped open circuit after a surge?
Cheers
Dave.
