Depends.
Everything (wires, circuit boards, X caps, Y caps, switches, etc.) must
be protected against the effects of overcurrent. If the part is not

For my specific requirements, (I can't speak for anyone else)
On the same subject,
Where do you put the AC mains fuse relative to the "X" capacitor used for the
EMI filter?
How does the "accross the line" safety rating of the capacitor affect this
answer?
Specifically. Would you put an X cap in the unfused area of the AC inlet
like the EMC fellow wants?
The important thing to remember is the function of the fuse. 99%+ of the time
it is for fire protection, not essential overcurrent protection. Most of us
rely on the customer wall outlet to be properly protected per NEC or 950.
For this case, electrical position before/after a switch seems not v
