Amendment 1 of BS7671 17th Edition Wiring Regulations

by Steve on March 20, 2011

Here is some information about Amendments 1 of the 17th Edition.  The new green version of BS7671 was published in July 2011.  Copies can be ordered from the IET including a digital version in the form of an ebook.   Also available from the Electrician’s Blog Amazon Bookstore (about £60 inc free delivery).  The new regulations will come fully into force on 1 January 2012.

There are obviously varying views from electricians about yet another edition of the Wiring Regs. Opinions range from resignation (almost literally!)  to blood boiling frustration. You can check out the comments section at the bottom of this page.

I have included  a link to an IET pre-release webcast video presentation, giving an overview of the changes, at the bottom of this page.

BS7671 17th Edition Amendment 1

BS7671 17th Edition Amendment 1

Here are the main amendments:

Amendments to part PART 4

There are changes to tables 41.2 & 41.4 due to new fuse standards being introduced:

Old  BS 1361   changed to BS 88-3
Old  BS 88-2-2 changed to BS 88-2
Old  BS 88-2-6 changed to BS 88-2

The effects of these changes are:
• Some Zs values are different
• Withdrawal of certain protective device ratings i.e. 15A devices
• Some time current tables in Appendices are altered

New Section 444- Measures against electromagnetic disturbances.

This new electromagnetic disturbances section provides recommendations to enable the avoidance and reduction of Electromagnetic Interference (EMI).

Electrical installations which include sources of electromagnetic disturbances could be transformers, Welding machines, electric motors, fluorescent lighting and where switching of inductive loads could cause EMI.  Also includes routing of cables and inducing of voltages.

Recommendations also cover installations where EMI may disturb or damage IT systems/equipment and electronic circuits and components.

++++

New section 534- Devices for protection against overvoltage. Selection of Surge Protection Devices (SPD).

Transient overvoltages or surges could come from lightning or switching of electrical circuits.

This amendment includes requirements for the installation of Surge Protection Devices (SPDs) and filters to limit transient overvoltages and divert damaging surge current away from sensitive equipment such as computers and electronic circuits.

More info about Surge Protection Devices.

++++

New section 710- Medical Locations

This section involves the safety of patients likely to be subjected to the application of electrical medical equipment in medical locations such as hospitals and dental practices.  This includes shock protection and secure supplies for life support.  Section 710 also segregates medical locations into 3 groups 0,1 and 2.

++++

New section 729- Operating or Maintenance Gangways.

Mainly concerning Electrical Switch rooms and Restricted Areas.  This amendment ties in with Regulation 15 of the Electricity at work Regulations and includes requirements for working space, gangway width, operational access, emergency access, and emergency evacuation.

++++

Appendix 6- New Model Forms for Certification and Reporting.

This amendment brings in the new Electrical Installation Condition Report which replaces the Periodic Inspection Report.  More information on the new Electrical Installation Condition Report.

Minor Works amendment NOT introduced.

Note- There were to be changes regarding exceptions to RCD protection where Minor Works are carried out and where SELV and PELV cables are concealed in walls.  The important thing to know is that these “proposed” changes (mentioned in the video) were withdrawn and don’t feature in the amendments.

note i have read some of your coments about under qualified part p fitters i agree with some of the coments regarding lack of knowlege .But whilst in the field i have seen some really poor work done by so called c&g installers most time served apprentices actually have been able to connect into boards when course finished and they are said to be qualified also an apprentice working in a domestic field is able to be fully qualified without accually working on a 3 phase system .As with all trades you learn as you go all trades change as things progress. Amendments of regulations help electricians move on with technology safety moves technology forward.

Dipsok September 22, 2012 at 22:14

Thank you very much Steve much appreciated.

Editor September 19, 2012 at 18:59

Hi
Appendix 5 contains info about codes for ‘Classification of External Influences’. It also gives a concise list of external influences.

For example the codes AA4, AM2, AQ1…
All the appendices can be found towards the back of your regs book (when you get it).

I hope this helps. Steve.

Dipsok September 18, 2012 at 19:18

Hi i am at college studying for my 2365 i am currently awaiting my wiring regulations book. I need to know what appendix 5 relates too if anyone could help would be great.

Donlunn July 22, 2012 at 20:12

Why you electricians are moaning i have no idea.I am a fully qualified mechanic,and we have every tom dick and harry thinking they are a mech just because they can work from a backstreet lockup.Then we all get tarred with the same brush,when they turn out a load of crap.At least your trade is regulated.Wish all we had to do was buy a book occasionally.

David Christmass May 21, 2012 at 22:39

You C & G fellows are right there with the criticisms.

I done a TEC qualification, we were told it ranks above the standard C & G courses which run for 6 months as opposed to 2 years.

Maybe you guys won’t to start thinking about upgrading the course, and getting shot of the CG bollocks!

It seems to me, that most of the regs focus on common sense issues, e.g. surge protectors and transcient voltage protections.

My perspective is that it is really impossible to legislate against every eventuality. A good deal of safety depends upon something failing at some point, I mean out there in china, kit is designed to have a set life period. At our level we got taught to think hard, and improve, you know nothings good enough, things always evolve.

When I think back to when I first started, most ccts pcbs were designed with sticky tape and trace papers, then photo etched. No cad programs, no traceroute or laser jets or gerber. Of course things improved with computer designs, but the point here is, how can anyone be critical of things designed of their time?

I look back at valve guys with respect, I mean, if you goofed on the development prototype design, the valve went, so those guys had to be exact, you know, not a 3 pence old bc 108 to change over, but a £3 pound EO 8 valve! That’s expensive.

Things like, emi field problems, so what are you gonna tell the boss with troubles from a dis case in a power plant room, that he’s gonna have to shell out for 1/4 of a ton of mu metal and silica steel for the walls? Like what I had to do on one job
in 1994 to stop rasters moving on a CRT? Never bothered the LEB for 20 years to shift the street cable, so why all the concerns now the problem got screened out?

But the most important point I want to make, about this division, is that BEAB standards, ain’t there. Seems CE is good enough for the merchants, but not good enough for the british beef! Just to advise, anyone unclear on what CE stands for, it means Certification Europe, which basically means a product passes the minimum standard required for a product to be sold within the EU. That can surprisingly mean sweet fa. I examined some ever ready NiMh chargers a while back, the components were real low grade chinese carbon resistors, and there was one, only one thermal device, that covered all safety cut outs. Also, has anyone had one of these low voltage AC switchmode adapters blow out on them? A switch mode adapter, what, 4 quid, but the design backs a punch, so wheres the transient voltage supression there?

I am finding it real hard to find a ready supply of linear psu adapters out there in the high street, as the craze shites are all selling switchmodes, cos they use less iron, and are lighter to ship, so I thank heavens there are UK manufacturers that make them!

Look closely at things, and you start to realise, just how absurd these documents actually are.

I am with you all the way, the regs should have been right in the beginning, and do these guys actually really care, I mean if they can just shunt off the BEAB, due to lack of funding, do they really give a shite about safety, or is this just some kind of legislative measure, to pass the buck over on the liability steaks.

I empathise with my mothers view, good honest people trying there best to do the job right, get completely shunted up the arse for their efforts. Maybe if these shites in the offices that make these rule, had to busk it with the reality of existance that occurs to people when no shite can take legal resposibility and therefore leaves the job undone, maybe they would change their attitude.

Theres a lot of people really thankful in the UK for the can do attitude, of the trade, and these stuffed shirts really don’t help the industry. Recommendations, fine, everyone stands and benefits well from improvements, but this shit ain’t about that, its about stuffing practical people up the rectum, just for doing there jobs the best they can.

Oh well, another set of regs pass me by!

Editor April 12, 2012 at 10:15

I also tend to agree. I accept that electrical safety regulations have to change to keep up with new technology and as a working electrician I need to update my knowledge. But electricians seem to be thrown an increasing amount of hoops to jump through and are expected to pay for the extra time and effort it takes, just to keep doing their job. continued…

duncan laughlin April 11, 2012 at 22:11

totally agree with phil. what other trades have to do b***** exams & buying books all the time,15 years in the game & i wouldnt recommend to anyone to be a spark.

phil April 10, 2012 at 18:18

ive been an electrical contractor for sometime now and i’m sick of paying money out!
sick of paying for updates. this should have been sorted by now! what a money making machine!!
These engineers know exactly how to make money for their companies
if i employed these engineers i would have fired them by now. oh sorry of course you get a bonus when you forget to insert a regulation. it can go on the next one. those little idiots out there will pay..
not any more!! they have ruined the job. i’m all for regulations for safety it shouldn’t take this long to get it right????? its made more complicated so it can be exploited and twisted to make more and more dosh. well not retiring yet but being an electrician just aint what it used to be……. bye bye
this will be my last year after 30 yrs of having regs swapped and changed. does anyone want some free regs ive got a room full. thats only 10yrs worth.

Editor February 1, 2012 at 15:54

Hi Neil. I’m pretty sure you’ll need the new green regs book since 1 Jan, but you can check with whoever does your inspection before they come. You’ll get a list of requirements to make sure you have everything ready.
There is a lot of outlay and hoops to jump through because in effect you’re setting youself up in business for part p. It gets easier once your 1st inspection is over and then you know what to expect each year. All the best- Steve.

Neil January 31, 2012 at 20:51

Like Andy above, I am also just starting up. I’ve passed my exams and I am thinking of joining NAPIT, and have the necessary work to be examined all planned out. My question is whether I need to buy the latest amendment, bearing in mind my old “red” book is less than a year old. So far it’s just been outlay after outlay. What have I done….

ray January 31, 2012 at 19:30

Hi
The snobbery from some of you sparkys is pathetic. Being an approved contractor just means your an idiot for paying more fees to the crooks at the NICEIC. Why would anyone pay above and beyond what you have to pay. Part P is law, make sure you are fully qualified and registered for that. You think an approved contractor means you are more qualified because the NICEIC tells you it is. The way you wear that stupid logo with pride is laughable. GET A LIFE AND STOP WASTING YOUR MONEY!!

Thomas January 27, 2012 at 11:24

Hi all, yes I do say it costs me loads of money getting certificated to carry on making a living for me and my family, no help from government , all I ever do is keep paying out for updates, courses certificates, totally fed up with the lots, think I will stack shelves at Tesco no certificates needed there. Still I.E.E more regs more money more things to take away our living away, GET REAL!!!!!!!!!!!!!!!!!!!

Andy Ward January 25, 2012 at 10:22

Thanks for the kind support and Steve
All the best!

Editor January 24, 2012 at 22:20

Hi Andy
Yes it’s definately a catch 22 when you’re starting out. You need to get a few jobs finished and ready for inspection. They can be small jobs but make sure all your paperwork and documentation is good. I am with Elecsa and they are very helpful.
http://www.elecsa.co.uk/Contractors.aspx

It will also definately be worth asking for some advice in the forums.
http://www.electriciansblog.co.uk/2009/04/electricians-forum/

Don’t be put off by all the red tape. It’s not so bad once you’ve got over the early obsticles.

Good Luck.- Steve.

Andy Ward January 24, 2012 at 17:47

Just starting my own company. Can anyone give me a bit of advice please as to what comes first. Nic registration with no jobs to inspect yet or do the jobs then get them inspected. Same for Napit membership it seems to be a bit of a catch22. Any advice would be greatly appreciated

Martin January 23, 2012 at 22:29

The comments about domestic installers are unfair when you consider that the same testing abilities are checked on the anual visit. In fact a full scope domestic installer ( niceic ) is no diferent than an approved contractor when checked on testing. The difference is that approved contractor is usually doing more than domestic installations.
There are many companies who are approved contractors where the qualified supervisor never sees the job and just does certs. in the office from the testing done on site by his electricians. At least the smaller companies usually have the qs on site filling in the certs. from his test results. More accurate I would say.

duncan laughlin January 11, 2012 at 20:27

raith you are bang on the money,ive only had these books about a year and now they’ve ammended them,i went into waterstones to see if i could buy the amendments only (like hell you can) they only £80 for bs7671 & £24 for on site guide.
oh and another thing that they are doing is de-skilling sparks so they pay x- amount for tubing x- amount for wiring etc,and another gripe of mine is these part p two week electricians youre destroying our industry.rant over with

martin December 31, 2011 at 18:27

After 35 years experience and an niceic domestic installer, I am within my rights to carry out pirs on green certs. Cant be bothered to be approved as long as part p is satisfied.

David Browring December 4, 2011 at 19:32

I am a director of an electrical contractor company NIC EIC APPROVED AND DOMESTIC INSTALLER APPROVED. My concern to the industry is the green periodic inspection forms or the new electrical installation condition reports. Non approved contractors use these green forms to carry out periodic inspection reports and miss lead the consumers. The consumers do not know the difference between red and white forms. I thought the NIC EIC was there to protect the consumers. I have informed the NIC EIC but no reply to the situation. I know why they are getting money for the green certificates.

dennis robbins November 10, 2011 at 11:45

I can see where you are coming from, I have the same problem and after some deliberation
from building control I eventually got my customer the Inspection certificate he payed for
but it was a case of are the Is dotted and the Ts crossed and the Inspecting official
didn’t seem to know what he was there for and said is it in line with BS7671 my reply
was have you read the completion schedule I sent in, his reply was, well it’s not the certificate I recognise, I asked him if he was going to do any checks and his reply was
he wasn’t really qualified to do so and just looked at the meter and fuse box, did no
checks, left and left no completion certificate, I then made numerous phone calls to
building control and eventually said there was some misunderstanding and they would
send on the completion certificate to my customer, my advice to you is with you’re
qualifications and experience don’t be put off by officialdom, keep in mind you know what
you are doing and go ahead with it, I know what you mean when talking about part P
its a bit of a misannomally. Nice to chat to you

Barrie Price November 9, 2011 at 16:08

I’m a retired electrician who until a couple of years ago was an NICEIC approved contractor for 25 years. Yes, approved contractor carrying out mainly industrial installations and maintenance, not one of the “Part P” brigade who display the NICEIC logo.
How are the general public supposed to know the difference? What really annoys me is the fact that I could be prosecuted for carrying out certain electrical work in domestic premises if I don’t pay building control a hefty fee. I feel there should be some sort of lee-way for people who have served the industry all their working lives.

Jay November 5, 2011 at 07:33

It’s the corporations who own the rights who set the price; have a go at them, not the engineers they don’t see any of the money.

raith wilson November 4, 2011 at 09:59

one more thing if you think bs7671 is expensive i had to buy the bs 5939 fire recommendation 380.00 for 200 odd pages of printed black and white a4 paper without a with no cover just a piece of cardboard they ought to jail the ******* lot of them

raith wilson November 4, 2011 at 09:54

im a niceic approved contractor .this is becoming pathetic.electrical science has been discovered years and years ago by the greats faraday watt voltair henry joule this list goes on and on.and you know what?the electrical principles discovered by them are constants and dont and never will change.on that note why in 2011 are the iet constantly changing the regs and demanding extortion for it .surely they knew all this stuff before.incidently i and i alone are the reason for the change in regs to rcd protection by using dual rcd boards.i suggested it in writing to them and they used the idea and ripped me off basically.i never saw a penny but it was my notion not theirs .so clearly they are a bunch of scientific idiots who cant i can see common sense in engineering .

steven September 27, 2011 at 12:08

oh no, not more money to fork out, im a fully qualified electrician who just seems to spend my hard earned money on courses, books, assesments, NAPIT membership fees and everything else that goes with it, i know so called sparkies that have never seen a copy of the wiring regs, never owned a test instument and never taken a course, yet they still go out, do the work and take the money. must be nice when you can keep the money you earn rather than spend it on the scam called PART P. they say there is a shortage of electricians, i wonder why that is, not sure i can carry on much longer with this rediculous situation.

Jay September 23, 2011 at 06:30

Should they give the standard for free? These guys are experts who’ve spent years at university. They don’t get paid a lot. In fact the people who make the real contributions on the panels may not make any money at all. It’s the corporations whom own the rights who set the price; have a go at them. But they’re the ones whom take on the responsibility and all the risk. I’d expect to be paid hansomely for that too.

These Standards make engineers and electricians lives easy and most importantly ensure safety.

Simon Veal September 15, 2011 at 12:37

Steve

Is there a requirement to upgrade or retake your 17th edition C&G course to remain in-date following the issue of this amendment?

Thanks in advance,

Simon

Steve September 3, 2011 at 15:39

Hi Carl
Thanks for your comments.
As said above I will probably get online version.
Not sure how you’ll show this for assessments though?
Take laptop along? Most of my certs are on computer now.
Get password for ERA when you otp-in to eNewsletter.

Carl Ramplin. September 1, 2011 at 10:46

Hi all. Great blog, nice to have a source to share opinions. I’m definitely with everybody on the amendment, we’re being fleeced and that’s all there is to it. Many of the changes are only editorial, there’s no need to purchase an entire book when the original is only three years old, all we need are the amendments themselves in a handy booklet or ebook.I’m about to have my fourth assessment, aren’t they great ? How do I get a password for the ERA ?
Cheers, Carl.

Steve August 26, 2011 at 20:04

Hi David

Thanks for your comments.
You’re right, you don’t need to pay £80. eBay Stores £59 or Electricians Blog.co.uk BookStore-
Amazon Price: £58.94 with FREE Super Saver Delivery.
http://www.electriciansblog.co.uk/book-store/
I’m thinking of getting the online version from the IET. Any changes will be updated automatically.
I guess this is the way things are heading.

And yes, we will need to get an updated On-Site Guide from Jan 1st.

Regards

Steve

Steve August 26, 2011 at 15:22

Re; New regs, on your web site an advert from eBay regs £59.00 and free delivery got one spread the news. With regards to the regs it gets goobled googe each time it comes out

Most of it seems to apply to engineers not to the electricians at the sharp end, now we will have to a on site guide, ect ect.

I would love to know how much is padded out from the cenlec regulations issued.

David Elgood

James August 17, 2011 at 06:48

There seems to be a lot of negative response to the latest ammendment of BS7671 with people complaining about the price of the newest version. I would like to just like to therefore make a few points… Read James’s points at: http://www.electriciansblog.co.uk/2011/08/amendment-1-of-bs7671-17th-edition-wiring-regulations-comments/

George culshaw August 14, 2011 at 07:49

Wow more money for the cowboys who sit behind a desk and never work in the real world. they wont people to do work in accordance to the regulations but they turn it into a money making scam instead of looking after the honest electrician. people are not going to pay out much longer. 3 more amendments and we will have to take the 18th edition. GREAT thanks electrical industry

Adrian Clarke August 10, 2011 at 06:05

As a retired guy I am considering going through the C&G courses to become qualified but am dissuaded by the cost of the BS 7671:2008 17th Edition book, even at Amazon’s discounted price. The ridiculous fee to then obtain the Building regs Part P to put into practice is pure extortion. Seems like these bodies are trying to emulate our revered Bankers to justify and also pay for their inflated salaries. Now they shovel out an amendment of what seem like minor or even trivial items and expect the working body of electricians to carry on coughing up extortionate amounts just to keep qualified. As “durham rader” said – Another money making racket, IET do provide an update section for purchasers of previous publications:- http://electrical.theiet.org/wiring-regulations/updates/index.cfm -: not that they provide anything for free. I believe they have devolved into a bureaucratic Quango who’s sole purpose is to siphon out money from anyone who wishes to have the qualifications making into a restrictive and restricted Guild going back to the 17th century.

durham rader August 2, 2011 at 18:09

another money making racket against the honest law abiding electrician ,is it worth it

Nick July 28, 2011 at 23:28

Day light robbery! Can I just buy the amendments?? Thanks

Steve July 18, 2011 at 18:58

Hi Dennis
The IET have 2 digital packages, designed for domestic and industrial installers. You can get 17th Edition versions of these publications and then automatically receive Amendment 1 versions as they are published. I am considering trying the 14 day trial and would be interested in hearing from anyone who has. Find out more at http://electrical.theiet.org/wiring-regulations/digital/index.cfm

dennis robbins July 18, 2011 at 12:22

Would someone let me know where I can get the latest ammendments to the 17th Edition wiring regulations without having to buy the new book and is it possible to download the aforementioned

Eras July 16, 2011 at 09:22

Rod Johnson……

Exactly my & many others people’s thoughts, another big money making scam.
Parasites are less blood thirsty!

Rod Johnson June 11, 2011 at 22:01

Authors of best sellers make millions on books costing £10 or less. There is no way that this book costs anywher near £80 to produce so the motive to bring out amendments is clear. Roll on retirement.
