Books and guides

I also have an old copy still BS7671:2008 but not amendment 3. However I no longer work so don't really need it, I am still a member of the IET so still get to go to lectures so got a good idea of the changes.

My On-Site-Guide is even older when I took my C&G2382 the new OSG was not published so never bothered. I do refer to BS7671 but don't think having the latest is really needed.

As to other books well I have (well my son has them now) my University text books but to be frank working out Thévenin's theorem is not something I do day to day, and in real terms I don't need to know, if I do need to work it out I will use electronics work bench or an on line tool.

If I need to look up Ohm's law then time to contact Alzheimer's Society and give up electrical work. I am sure there are people who do need to work using Norton's theorem but I can't recall using it once in my life time for a real problem. In fact don't know If I could any more.

Depending on the branch of electrics you are in you may need other books, I refer to the PDF guides for the Parts of building regulations but have never bought the full versions. I will admit some items are passed by word of mouth and I some times wonder where the rules came from. Be it drilling a beam 1/3 in or working out the volt drop on a ring final using 26A as design current I have never found where they are written down.

I some where have a copy of GS38 but that is hardly a book there are only 9 pages. However as to being up to date one I have is 4th edition the same with best practice guides I down load and read them however there is no update service so could be well out of date. So only book I refer to on a regular basis is BS7671:2008.

 

If your out in the field or on site it will not do me old china

 

I went in to get a book on suicide, but someone hadn't brought it back.......

 

Just received it .
Yes it is worth the money.
It has 208 pages.
Have to look out for the errors though.

 

Has the incorrect Zs table on page 125 been corrected yet?

 

I have only Brian Scaddan's 16the Ed To compare. The B Type MCB values of Loop impedance, which are the only ones I am interested in , are similar but not quite the same.
EG;- "16Ed" 6 amp 6 ohms, New OSG 5.87
16------2.25 -------------- 2.2
20------1.8---------------- 1.75
32 ------1.12-------------- 1.1
50 ------0.72-------------- 0.7 ETC.

Just rounding I suppose

but type 1 mcb
6--------7.5 --------------- 7.28 ?

 

O.S.G Errata

On-Site Guide - 2015 edition (yellow cover) errata sheet

 

When you buy any book it always pays to look in the erratum or corrigendum section.

Beat me to it Deleted member 11267

Thanks Deleted member 11267 . And Yes JP the incorrect figures have been corrected in the main body of the guide( not as an errata sheet RS).

 

Don't do it people

 

Thanks Paul and Dobs for the info

 

My mate got crushed by a pile of books, but he's only got his shelf to blame.......

 

Hey, where are you?

 

I got my one for a little less off of Amazon quite some time back..excellent little guide tbqh.

Agreed. I would call it an essential bit of kit, it literally tells you, step by step how to do your initial verification and the correct order of tests to perform. It tells you in real man's talk how to do the tests as well, they allow to use this book on your AM2.

I wouldn't bother with the big yellow book, it takes months to learn how to use it and even then it's open to interpretation, it feels like it's not designed to help or clarify anything

 

I wouldn't bother with either if we didn't need them for part ****.

Other guides by Brian Scaddan - I suppose there all much the same really..although I am speaking from a diy domestic wiring slant. What these guides are like (including the osg) for industrial/commercial electrical deployment I would not know.
