Regarding the MOV: for professional appliances a fused MOV is common;
they
Mostly have a "fused" indicator or even output. In ordinary (low cost)
applications, apply the MOV behind
the fuse and buy a approved type UL VDE or any other reputed tested
version
and not low cost far east models. Behind the fuse the end-of-life short
does simply blow the fuse, and does not ignite the device.
Unfortunately, fuses compromise the modern requirement for
'availability'. Still, if it was too easy anyone could do it.(;-)
