BAS please calm down - and breath deeply -I can feel your blood pressure rising. Its only a forum
Rather than calling me a liar, perhaps you should, like I am, consult with the Communities and Local Government Department. I am sure they will be able to confirm which edition of BS7671 the Approved document Part P now refers to.
I do not understand how you can consider the 16th edition to be as safe as the 17th edition. How can you support that belief when the 17th edition introduced the requirement for additional protection in special locations like shower rooms.
As you know, 50mA is more than enough to kill someone. Under the 16th edition a 8.5kw shower has the capacity to generate a lethal 36 amps under short circuit conditions. When, the circuit has additional protection that capacity is limited to 30mA for less than 20ms. You will still get a belt but it should not kill you.
So yes I would state in court, on oath, that the 17th edition is more safe than the 16th edition. I would also say that the 17th edition is the current standard that must be used for all new installations, additions or alterations. I do not know of one LABC who would validate installations under Part P against the 16th edition. Do you know of one, if so please advise me where it is?
By the way, what is you aversion to plumbers?
