Buried cables

RCD protection is now required for

  1. All sockets up to 20A for general use by ordinary persons (reg 411.3.3) eg all house sockets, garage sockets and cookers with a socket outlet
  2. All circuits in a bathroom (reg 701.411.3.3) eg lights, shaverpoint, electric showers
  3. All circuits buried in a wall at less than 50mm and without mechanical protection.(reg 522.6.6) eg most cables in a normal home 

1&3 appear to contradict each other. Could use clarification of eg whether buried cables to a freezer socket require rcd. NT 20:56, 19 March 2011 (UTC)
