what kind of wire?
is the wire surrounded by silica sand?
open in what time frame?
All hv fuses create a metal vapour arc when they open. Until the arc
extinguises, only about 20v is dropped by the fuse. Thus, fuses are not
a surefire means of limiting peak fault current during a major glitch.
My unsolicited advice is that a glitch R is a better way to limit peak
fault amps to a safe value. . // Why have a secondary HV fuse when you
already have a primary circuit-breaker?
