Ken,
I'm really not sure just how accurate a fuse would be. My opinion, I doubt very
good, maybe like the light bulb. The thing is, one would have to know the surge
current it takes to blow the fuse as actually a fuse will not blow right at
it's rating or I have never seen one that would unless it was a surge that hit
it. In this case I would be bringing the current up slowley with the variac.
What I was hoping to do was use something readily available here like an
appliance which I could test easily and get a decent result. I may end up
having to go to the bench on it as I just cant think of anything else.
Best,
Will
