Hi Larry, All

  I replaced the 240v 40A fuse on my Powerstat 9kW variac with a piece of 
copper strap, and rely on a breaker to trip when current gets excessive.  I 
hate replacing fuses, and Murphy's Law says you'll not have a spare on hand 
when you need it, and if you bridge the fuse without any other overcurrent 
protection, you'll melt something down.  My breaker I rely on is the 60A 
breaker in my breakout box in the garage.  When it trips, I loose 240 from 
the box out, killing the pig, variac, and ballast all at once.

  Just my $.02, YMMV
