   >Not sure what you're planning, but if there is ANY wire smaller than   
   >#12 anywhere in the system before or after your 20A breaker, you've got   
   >a problem.   
      
   Electrician I asked said something that I interpreted as similar.   
   I'm having trouble with this one and think either something   
   hasn't soaked in yet or I talk too fast/write too verbosely and   
   am muddying the waters.   
      
   For the sake of argument:   
      
   - One 15-amp breaker  (NOT 20.... the twenty amp fuse   
     is in the switch's circuit feeding the 15-amp   
     breaker)   
      
   - Three circuits hung on that single breaker.   
      
   - Each circuit's wire is spec'd to handle up to   
     15 amps.   
      
   - Seems to me like no single wire can experience more   
     than 15 amps because the breaker will trip at 15.   
      
   - The 20-amp fuse in the switch (instead of a 15-amp fuse)   
     is so that the breaker will take the hit on overload   
     and the fuse will be less likely to blow.   
      
   Do I have it right?  If not, where am I going wrong?
