   ** Fuses do not stop electronic gear from smoking and catching fire -  the   
   number of fires from TV sets and CRT monitors is proof of that.   
      
   Fires do not take hundreds of watts to start and where the cabinetry is of   
   flammable plastic - watch out  !!   
      
      
   > So for example, one estimates mains input current ...   
      
   ** Huh ??   
      
   Might be an idea to MEASURE it with a * true rms * AC current meter - allow   
   for the worst case operating conditions and then add say 20%.   
      
   Slow blow fuses are essential for AC supply fuses used with anything that   
   has an internal DC supply.   
      
   BTW:   
      
   A user replaceable fuse is no protection against ANYTHING !!!
