Huh? What? Might want to study Voltage Ratings of fuses a bit more.Fuses have voltage ratings for a reason - it means that the element will blow open at that voltage. Using a 250 volt fuse in a low voltage circuit means the fuse may not open on a fault, giving no protection.
<snip>, I hate when that happens but it does! I'm always telling the wife.. " Oh yeah! I'll bet my left <snip> on that!"... and she says .. "Oh yeah! Well, you bet and lost it a long, long time ago!"I may have misremembered - http://www.circuitprotection.ca/fuseology.html
