With the publication of the fifteenth edition it was decided that in future reprints of the same edition (amendments) would be contained in one of five different coloured covers red, green, yellow, blue and brown, a new edition would be published when the brown covered reprint required updating.

1981 The 15th Edition of the IEE Wiring Regulations launched

1991 16th Edition of the IEE Wiring Regulations published (adopted as the BS in 1992)  Electricity at Work Regs. (Northern Ireland) come fully into being

2004 Part P of the Building Regulations becomes law  BS 7671:2001 Requirements for Electrical Installations (Incorporating Amendments No 1: 2002 and No 2: 2004), The IEE Wiring Regulations (Sixteenth Edition)

2007 17th Edition BS 7671:2008+A3:2015 (the 17th edition incorporating Amendment 3:2015) issued in 2008 and updated (“Amendment no. 3”) in January 2015 and mandatory from July 2015.

    This is brilliant as I’m one of those old electrician’s that started with the 13th Edition and it was great , please do note that this is my second leguage and in the begining I found it somewhat difficult but in the end I made it and qualified .
    We all in the electrical industry have a duty and a moral code that we insure that our standers are kept to a very high level .

    It is interesting to read and note that the changes to BS 7671 over the years have been driven by technology. I remember the days of the standard tester which measured continuity and insulation with a flick of a switch on the side and the instrument was wound by hand. The instrument had two scales with a moving coil instrument movement.
    Now, with the 18th edition arriving possibly next year I have heard that ring final circuits will (possibly) not feature within them.
    The reason? The ring final circuit was the answer to the problem of socket provision. There is no limit to the number of sockets on a ring final or, for that matter, on a radial final.
    Older installations were all radial. Each room had one light, one socket, finish. The introduction of the ring final meant that a fairly large amount of power could be supplied by this means in a household. Ring finals were, initially, not confined by the floor area as they are currently.
    What is driving this? It looks like the move to lighting that uses less power and the move to less powerful socket fed appliances is responsible. We know that appendix 15 speaks of limiting socket fed loads to 2kW but there is a little bit more to this. Further, vacuum cleaners are now destined to draw less current and it is possibly only a matter of time before the power consumed by other items is also limited by one means or another.
    This means that the total power needed from a socket circuit is reducing with time. It could be that edition 18 may not include ring socket circuits and may only speak of radial socket circuits.
    I know that there are arguments for and against ring and radial circuits. One argument against ring finals is that one circuit protective device protects two conductors. Some, for a long time, have said that this is ill-advised. Appendix 15 states that loads should be equally shared around any ring final but is this easy in a modern dwelling?

      Ring circuits are useful when portable electric space heaters are plugged in. You cannot get reduced power space heaters. I hear the cry; No one uses plug in space heaters!
      People also use all other kinds of portable plug in appliances such as ; dehumidifiers, air conditioning units .
      This is change for no good reason.
      Ring mains have provided years of trouble free service , leave them alone.
