Is a 250V fuse appropriate for a 115V AC IEC320 connector?

[Zachary Yarashus]

A fuse with a higher voltage than the line voltage is fine. Given that, the
amperage is the critical part, and maybe fast/slow blow depending on your
application.

If you intend to use it with a switching supply that accepts 120-240VAC
(which are becoming more common) it should have a 250V fuse in the case
that it is ever run from the higher voltage. If it can only be run from
120VAC, than any fuse with a voltage rating of greater than or equal to
125VAC should be fine.

Personally, I'd just use a 250V fuse since they seem to be more widely
available than lower voltage fuses from what I've seen.
