Hello All
Thanks for the replies.
I was at college the other day and found a regs book from 1997. It says you test between live conductors and between live conductors and earth.
No mention anywhere of cpc connected to system earth. This means....
In 81, I was taught the way I was taught... The way I did it till a fortnight ago.
In 97, I was still doing it right, just as the big book in college says.
Now I do not know when they changed the wording....so the best I can comment on now is...
In 07, I wrote my first book with my 'old and possibly wrong' method - four figure sales and no one commented.
In 09, I amended it to the BRB with the same old IR testing which was now definately wrong- double the first sales and no comment.
In 12, I am having it proof read by one of the committee guys on p10 of the BGB. He tells me I am wrong! Me, a doctor? Of course I love a good debate and ask him to prove this to me, which of course he explained in detail...
I have spoken to a few sparkies and my revelation is also a revelation to them, so it appears....
That the IET changed the wording to reflect some sort of scenario that they had thought up or had reported. That is fine, however, they never bothered telling anyone about it:innocent
