Hello Everyone,
I am sorry if this book has upset you.
I think the correct word is not upset, but entertained.
The reason that the punctuation is the way it is, is because I am trying to speak slowly for the benefit people who aren't as bright as you believe that you all are.
It's not though, is it? It's because you are not as literate as you believe you are.
My qualifications are all distinctions and merits.
That's no what "no higher qualification..." means on your certificates.
This book is simply the 16th edition put into pictures.
No it's not. It's just wrong.
The 17th edition is based on earthing standards from around the world written by people with no experience of British conditions...
Cobblers. The earthing (and bonding) requirements are, in effect, identical.
The terminology that you use at this time has only been made possible by first removing the definition of "earth leakage current" in 2001.
Only after 2001 when I first spoke to the iee and pointed out that they had mis-used the word 'radial' did a legal disclaimer first appear in BS 7671. Prior to this it didn't need one.
As I have access to a large library, I'll be checking this and getting back to you. By the way,
you seem confused about the term, so you might want to check.
2001? Is that why you've chosen to use 911 in your username and email address? You're a funny guy.
The word Extraneous is used in the 16th edition to describe things that aren't part of the electrical system, therefore any earth cables associated with extraneous-conductive-parts will always be 'supplementary' to the electrical system.
The definition of an extraneous conductive part has not changed and the main bonding conductors are still the
main bonding conductors. Supplementary bonding conductors are supplementary to the main bonding... I can see how the use of English may have caused you this confusion.
If in future years somebody comes up with a way of automatically disconnecting the supply, based on the capacitance of the human body then we will no longer be reliant on eebads. But at this point that seems unlikely, therefore we are stuck with it. For one thing it is the only method of protecting ourselves from 400v phase to phase contact, secondly as we live on a saturated island in the middle of the North Sea therefore it is also the best way to stop people from killing small children and the elderly in their own homes. If you don't believe that you are in contact with earth, buy yourself a neon screwdriver.
If you don't understand this subject - and clearly you don't - what on earth possessed you to write a book about it? You should Google the phrase "unskilled and unaware" and read carefully.
I am also a successful contributor to BS 5839-1, our fire alarm system standards. An awful lot of the amendments that I have put forward have also been deferred to the next major re-write. If Geoff Cronshaw was honest he would also admit that it was me who suggested using rcd's to protect all general purpose socket outlets.
Well, we might find out, as I've asked Geoff for a response. (Although I rather think he may have more pressing matters; working out how to incorporate all your genius suggestions in the first amendment.)
