Rick,

I'm not sure what type of fuse is best, but one must take
into consideration that an NST can draw a wide range of
currents depending on; input voltage, type of spark gap
(bps, phasing, gap spacing, etc), capacitor value, and
PFC.  I've seen 15/30's draw only 500VA, and I've seen
them draw 1500VA, depending on the factors I've
mentioned.
