In fields in which I'm qualified and experienced to offer an 'expert view', I often do 'get involved'. However, no matter how much I may 'know' about the subject, I am not in that position in relation to matters of electrical wiring!
So, John, you feel competent to denigrate the committee's work on a public forum, yet not competent to join them and help them correct their mistakes?
I think you may have misunderstood me - it's not me, but 'the system' which prevents that happening. 'Competence' is a rather funny thing, not the least because it is often largely in the eye of the beholder, and because it is very often judged fairly superficially on the basis of 'tangibles' (qualifications, appointments, etc.) rather than by objective assessment of the actual individual.
Even though some will undoubtedly regard it as an arrogant viewpoint, I would like to think that I actually would have at least some useful input to offer in relation to to BS7671 and, if it were practicable, would like to be able to 'join them', as you put it, and see what I could do to assist. However, neither any of the letters after my name nor any of the appointments or statements about experience on my CV have any significant relationship to 'electrical wiring'. Hence, given the way the world works, I have absolutely no documented credibility in that field and do not think that anyone would be in any way inclined to 'examine me' to determine whether I had anything useful to offer.
In purely practical terms, you have told be that roughly half of the members of JPEL/64 are appointed by BSI, and the other half appointed by IET. Which of those two organisations were you thinking might consdier appointing me, and why on earth should they - particularly given that they presumably have an awful lot of far more 'obvious' contenders to consider?
If I can't 'join' them, making some of my views heard in a public place at least means that I am not 'keeping them to myself' (which gives me a little personal intellectual satisfaction), but there's also the outside chance that they might perhaps influence the thinking of others, and might even occasionally 'filter through' to someone who is in a position to make some difference.
Of course, if you have any suggesttions as to how I might be able to more formally 'join' those who are involved in drafting BS7671, I would be 'all ears'!
[and if anything deserved a sepaarte, 'spin-off' thread, I suspect that this one does!]
Kind Regards, John
