After reading a few of the comments about high voltage fuses, we may need a
reminder about voltage ratings. Using a 3AG glass fuse in a high voltage
lead is a very cheap and dirty method, but the 3AG fuse is rated at a very
low voltage rating and even if it blows, it may still conduct plenty of
current to negate even having the fuse in line. I am sure we all have seen
the vaporized metal covering the glass inside a blown fuse.
Also, using small wire for a HV fuse (which I have done myself in a pinch),
please be careful about the positioning and mounting of such a fuse. Make
sure when it does open, ends of the open wire cannot come in contact with
anything.
