   okay, maybe it's 12 A, never measured it, though.   
      
   exactly, I agree. that's the point of it, anyway.   
      
   not just the fuse, it would blow the whole meter.   
      
   I am an electrical engineering major and I have graduated from the   
   college here, Iraklion, Crete, Greece:-) And with an apprenticeship   
   under my belt I know a few things, because just the degree is not enough;-)
