I am adding two extra double sockets to my kitchen ring main and I was proposing to fit two 20 amp junction boxes to enable me to add the extra sockets. A friend said I should fit 30 amp junction boxes instead of 20 amp Is this essential? So far I have not seen any 30amp boxes in B&Q or Wickes Blair

30 amp - three terminals instead of four. Your nearest wholesaler will have them and happily serve you.
Lobster and Dave Thanks for your help Blair
