I had a look on Google at this which brought a wiki page up which says... BS 7671 is also used as a national standard by Mauritius, St Lucia,Saint Vincent and the Grenadines, Sierra Leone, Sri Lanka, Trinidad and Tobago, Uganda, Cyprus, and several other countries, which base their wiring...
Hi all, long time no see!
So I have this question that I need to answer for an assignment but there is an issue. I have a copy of the BS7671 Wiring Regs Amendment 3 (which has amendment 1 & 2 removed from the introduction).
Question 1 asks : Which zone no longer applies to a shower room?
The...
I've recently been to look at doing a eicr at a number of hmo buildings they originally were houses about 20 years ago
they were tested 5 years ago by an Nic registered company
ive noticed that most of the consumer units have no rcd protection and a lot of the circuits have shared cables
one of...
Hi, quick question....long answer!!
An RCD has been installed in a single phase circuit as the measured Zs exceeds mcb. Circuit's wired in thermoplastic T&E 2.5/1.5, length of 58m.
Ze is 0.33 ohms on TNCS system.The OCPD is C20 60898.
How do I determine what the residual current rating of an...

Where the hell is the answer to the following question in BS 7671:
The required current carrying capacity of a three-phase circuit conductor Iz is 26A. From the correct table, the minimum size of three single-core thermoplastic covered, heavy duty MICC cables, installed flat on a perforated...
Hi,
I have just purchased a 16th Edition and a 15th Edition BS7671 book both in excellent condition.
I am looking for a 14th and 13th edition if anyone has one they don't want.
No particular reason that I want them other than to look in and to have sitting on the shelf as it would be a nice...
Hi all
I'm unsure if it's appropriate to post this on this board but I wanted to get opinions from people in the industry on a sticking point with an electrician I currently have.
a bit of background - I am letting out my flat and as part of the pre-let safety checks I decided to go ahead and...

Hello, I am a new spark and even though I do not want to (and shouldnt do) eicr yet as I am not yet that competent, I am just really trying to expand my knowlege and be the best I can. My question is I have been reading the onsite guide on page 170 there is a list that one must inspect eg...
Evening...
I always use my OSG to find R1+R2 when needed for designing a circuit (staying withing the Zs limits), but I wondered if the same table is somewhere in BS7671? Its table I1 in the OSG. I've hunted high and low so I expect it's just something that the OSG offers and isn't in BS7671...
Hi guys. Just wondering if any one uses the IET guidance notes 1-8. I mostly refer to my regs books or on site guide and I'm wondering if they are worth buying?
Has anyone else noticed how little internet coverage there is for the compliance deadline of 1st July 2015 whereby all new overhead cabling in escape routes has to be fixed with metal clips? Whihc is strange because we deal a lot with councils and they have been stocking up for major changes for...
looking at zs readings for type b bs60898 circuit breakers in bs7671 "page58" and looking at page 121 in the guidance notes 3 and seeing different readings??
Clarifiation please !
I have read somewhere, maybe in BS7671 or on a forum site regulation that states that 16mm meter tails can or should be used on supplies rated at 80amps or under and 25mm tails on supplies rated at 100amps.
I have scoured BS7671 and various forums but cannot find this...

Q, The earth fault loop impendence measured for a circuit is
L1.1 0.61
determine showing all calculations weather it complies with Bs7671
what do I need to do
This would sort out most of the dross in this trade.
A legally binding code and compulsory registration.
Yes I know there’s a lot wrong in the NEC, there’s far more wrong in BS7671.
URGENT INFORMATION
The IET informed us that there is an error in one of the tables contained within the two recently released 3rd amendment publications below. We understand that this occurs in a table which many electricians will never use and is not going to affect anyone studying for the...
Is it a statutory requirement by law that Caravan (touring) Parks and Marinas be inspected / tested each and every year? If so, who implements that this must be done? The reason I'm asking this, as you know BS7671 is not statutory. I know it carries a lot of weight if any thing should go wrong...
Consumer units compliant with amendment 3 have to pass some kind of glow test to BSEN61439-3
I like many have seen and read information suggesting that all domestic consumer units will shortly need to be installed constructed of steel rather than plastic as a result of this new wonder ruling...
Please keep this on track and comments sensible.
I think that the IET et al are really taking the pxss with all the updates of BS7671 - the BYB due out in January, has hardly got life threatening changes so why update it now.
So please place your vote....
