   : Wire nuts were banned in the UK for very good reasons. Perhaps   
   you'd   
   : explain why that ban was/is wrong?   
      
   Did I say that, no. My point was and is that the world isn't   
   perfect, hence wire nuts are banned, hence why other mechanical   
   joints have to remain accessible, and why I consider ring   
   circuits a bodge at best.   
      
   :   
   : And you can very easily overload 'an appliance lead' on a   
   radial circuit,   
   : unless it is rated at the same as the radial protection. Which   
   it almost   
   : never will be.   
      
   Yes pet, a 15amp breaker has the same rating as 30amp breaker if   
   you say so... One is far more likely to have an appliance lead   
   that is rated at 15A, even for appliances that have internal 1amp   
   fuses, rather than such an appliance having a lead that one could   
   run a domestic -four ring, grill and oven- cooker off...   
      
   That is one great benefit of the UK final ring circuit -   
   : appliance leads are fused at the plug, and must be capable of   
   blowing that   
   : 13 amp fuse under fault conditions. Of course idiots who play   
   with   
   : electricity without understanding the basics can cause havoc.   
   You've   
   : proved that one.   
      
   The great advantage of radial circuits is that idiots find it a   
   little more difficult to bridge out the breaker in the panel,   
   unlike the silly fuse fitted in BS1363 plugs (which for some   
   silly reason is the same shape and diameter as many screws, bolts   
   and any other round bar) - again Plowman shows that whilst he can   
   read the regs and learnt by rope do doubt, rather than actually   
   understating the RISKS and therefore the whys and wherefores of   
   the regs. If regulations were not infallible we would never have   
   had wire nuts, but at one time they were allowed in the regs...   
      
   Indeed I have come across such "havoc", hence why I'm so critical   
   of ring circuits, they encourage such bodges. At worse a *radial   
   circuit*, protected at the panel by a 15A breaker is no worse   
   than someone like a table lamp (rated at 3amps) being fitted with   
   a new BS1363 plug and the default 13amp fused. At worse a /ring   
   circuit/ is like that same table lamp being hard wired into the   
   30A cooker connection...

   : But I understand the basics. And am capable of following the   
   regs. They   
   : can be bought in nice large print with coloured pictures for   
   those who   
   : have difficulty reading.

   I'm glade they were a help to you pet, it's just a pity that you   
   chose to only follow them, rather than fully understand the   
   rational behind them! :~(
