   Perhaps not 1amp but 3amp is common. But heck were back to   
   Plowman believing that he can run his 3Kw(+) electric cooker off   
   such leads as commonly fitted to table lamps...

   : All appliances now sold in the UK (and elsewhere in Europe) are   
   capable of   
   : blowing a 13 amp fuse in event of a fault on the line chord.   
      
   Assuming that the BS1363 plug is actually fitted with a fuse and   
   not a twist of wire, a lump of metal bar or the shank of a screw   
   or bolt... As I keep saying, and Plowman keeps refusing to   
   address, the sort of bodge (by a end-user who might not   
   understand the risks), that is not possible -or at least a dammed   
   sight more difficult to do- with radial circuits were the lead is   
   protected at the panel rather than plug.

   loading.   
   : Not some theoretical maybe as Jerry insist on bringing up -   
   even although   
   : it has been explained to him time and time again.   
      
   Err, what frecking cheek, Plowman is the one who keeps quoting   
   the theory, living in that perfect world were idiots are banned.   
   As for "Diversity" that in it's self is a bodge, it actually   
   acknowledges that a ring can be overloaded and thus one has to   
   guess to circuit loading the real world might bring and then if   
   needs be increase the number of ring circuits.   
      
   :   
   : Final ring circuits are for domestic premises only. For   
   workshops or   
   : offices where you have known fixed loads you'd stick to   
   radials. As you'd   
      
   Wrong, ring circuits are acceptable in offices and workshops but   
   the regs limit the total number of outlets on each ring.   
      
   : do for fixed heating in a domestic scenario.   
   :   
      
   Not just for heating, the 17th edition [1] has likely increased   
   the use of radials being used for freezers, fridges and other   
   circuits/loads were it is unwise to allow unmonitored   
   disconnections due to the RCD being tripped due to faults   
   elsewhere or even 'non faults'... But then, unlike Plowman, I   
   have always been in favour of supplying such appliances via   
   dedicated radials, ho-hum, could the worm be turning, could   
   people like Plowman be eating their own archived words come the   
   18th edition?!   
      
   [1] for those outside the UK, that refers to the current UK   
   wiring regs
