UK fixed wiring circuits, unlike those found in almost all other countries, make widespread use of ring circuit designs, as well as radial circuit designs often seen in other countries. (This was one of the recommendations of the Electrical Installations Committee, convened in 1942 as part of the Post War Building Studies programme, which in 1944 determined that the ring final circuit offered a more efficient and lower cost method to support a greater number of sockets.D.W.M. Latimer: History of the BS 1363and the ring circuit. Presentation papers from a public meeting to discuss the issue of ring circuits, IET, London, October 2007 (PDF in ZIP)) It continues to be the usual wiring method for domestic and light commercial socket and device wiring in the UK.
