Product Description

From the Author

Please remember that all printed material, including my books and GN3 are for guidance and you should use your knowledge, understanding and ability to make an assessment of each individual situation and only carry out a test in a way that you know will avoid danger to persons and damage to property

GN3 states that direct measurement of Zs can only be made on a live installation, neither the connection with earth nor bonding conductors are disconnected. Readings given by the loop impedance tester may be less than Ze + (R1+R2) because of parallel earth return paths provided by any bonded extraneous-conductive-parts.

In my opinion you should disconnect the main equipotential bonding conductors from the incoming gas and water service pipes if they are metallic in order to obtain a realistic value for Zs. (bear in mind that no other bonding conductors should be removed)

If the incoming gas and water service pipes are metallic and the test is carried out with the main equipotential bonding conductors connected, the measurement of Zs becomes worthless and the risk of shock induced into another electrical system in close proximity is un-quantifiable, In my opinion unsafe, uncontrolled and completely out of the hands of the inspector and defiantly in breach of H&S. --This text refers to an out of print or unavailable edition of this title.

BS7671 is the UK,s version of the wiring regulations.
After designing and installing installations,Electricians are required to test the installation for conformity to BS7671 and having read various publications that offer guidance to Testing electrical installations,this publication clearly rises head and shoulders above the rest.
Full descriptions on all aspects of electrical testing and illustrations in full colour for fantastic clarity.
This publication is an essential reference tool for electricians and anybody studying the city&guilds 2391 course.

I think this is an excellent publication. I take on board the comments about testing for Zs and I agree with the author of the book. I have come across installations where there is no actual true Ze, but it is being provided by other parallel earth paths. Testing this way is about risk assesment and there is a big difference between testing domestic and industrial properties. At least this author has had the courage to pragmatically show testing and the efficient and accurate ways to do it. Too many people think they know how to do it, but have never actually tried to do it. If they had they would understand the confusing results that you get with the effect of the parallel earth path problem - difficult to explain when the sums just do not add up!
My only criticism of the book is that it would have been nice to have had the Zs table and the protective devices table and fault current graphs included out of the regs. It would just reinforce why we are testing and what we are truly looking for.
But an essential for those sparks who need a refresher and don't want long winded explantions and an absolute must for any young sparks starting out, I wish I had this 30 years ago.

1.0 out of 5 stars Waste of money 26 Mar 2009
Format:Paperback|Verified Purchase
This review concerns the Sixth Edition of this book. If you know nothing about testing then it may help - somewhat. However as a 'companion' to the C&G Testing & Inspection course I found it poor, especially when compared to the IEE Guidance Note 3, which is an excellent book.

It's not particulary well written, the graphics (particularly of consumer units) aren't good and I found it slightly confusing. The 'official' 17th Edition Guidance Note 3 or the On-site Guide are far better value.

4.0 out of 5 stars Claire Kelly 12 Dec 2007
I bought this book because I am in my second year of Studying City & Guilds Electrical Installation 2330; attend two evening classes per week. This course consists of underpinning knowledge facilitating entry into a career as an Electrician, although I work full time in a completely different industry. I have found the book useful because the clear diagrams and attendant explanations can be used to back up testing and inspection on our practical work and during class discussions. I have recommended this book to my fellow students some of whom are electricians working to gain qualifications; they have found the information very useful.

5.0 out of 5 stars paul povey 26 Jun 2007
with reference to comments left by 'a reader' Below i would like to point out that for an acurrate measurement of ZS it is perfectly obvious you would indeed need to remove all 'Parrallel Earth Paths' from the equation.

It is without doubt a procedure which should be carried out under the safest cucumstances

i.e ( all persons and livestock NOT to be present during the test duration)

i feel your comments for saying this book is not relied upon to be completely irrational and totaly un-justifiable.

Testing and inspection nowadays is only carried out by competent personel and such personel would have the ability and knowledge to realise that this process of reading ZS is entirely required and should be carried out in a manner that would involve zero risk.

I think 'A reader' will now need to re-test every job he/she has ever tested as all of his/her ZS readings are most definitely inacurate.

this book is one of the best ever written on the subject in my oppinion.

keep up the good work trevor marks!!

Excellent precise reading for a 2330 student, very straight forward and uncomplicated. The size and content of the book is also perfect for reference and I apprecieted the fact that is is straight to the point without trying to be too clever - no offence IEE.
