    What Reg would you like to see added to BS7671? and what should be removed?

    Personally I would like to see a reg insisting on Isolation for fans and showers in Domestic installations, I am sure there are dozens of others as well, but rather than name more at this point, what do you lot think about potential new Regs? and also which regs should we get rid of?

    new yellow bs7671 regs

    Heard on the grapevine there is a new updated BS7671 book due end of the year which will have a yellow cover. Anyone know anymore? Is it another Amendment to 17th Ed or are we moving on to 18th Edition ?

    BS7671 Amd 3 consultation is out.

    The first draft of amendment 3 is on the IET website (I think you have to be registered to download it). No great changes apparently, slightly stricter RCD rules for socket outlets is the biggest change spotted so far.
