   A final circuit is simply one that directly feeds 'points of   
   utilisation' - lights, socket-outlets, etc.  A typical domestic   
   installation with a single consumer unit only has final circuits.   
      
   OTOH an installation in a larger building is likely to have a number of   
   intermediate distribution boards fed from the main intake via   
   *distribution circuits*. Said boards then feed final circuits or further   
   levels of sub-distribution (or both) .  Distribution circuits which feed   
   separate (out)buildings from a common supply intake are known as submains.
