Thank you for welcoming to this forums
I just want to clarify that the Value I need to enter 100% or 80% in the last column "Maximum Zs Permitted by BS7671"
is it 80% from the table 41.3 from 18th Edition Regs - Page 62 or the value from Pocket Guide 18
Hi, I'm Dave and I was wandering if I could have help with something.
If I were to wire a 5KW motor what means of protection should be incorporated into the inverter for compliance with BS 7671?
I'm after some old copies of BS7671. No real reason, I just like collecting them.
I'm just wondering if anyone can find any on the net, or if anyone fancies selling them?
The earliest I have is BS7671 : 2001 incorporating Amd 1 and 2 (2004) (Brown cover). There seems to be lots of these...
Just joined the forum. As a practising electrician looks like their is plenty of useful info so looking forward to getting into some of the threads. Also we have a small training company which focuses on the 18th 2382 and the Part P 2393 qualifications. We have just started a blog with...
Every now and then I have a look for old copies of the regs. I have them all back to 2004 (i.e the brown one), and am looking for any before that?
Does anyone have any that they'd be willing to sell?
Cheers chaps :)
I have just received my new copy of the 18th.
I am excited to read it as it will be so very different to the last one. I would have bought it anyway just for vast amount of new information, regardless of the fact that I am forced to buy it otherwise I cannot be registered as competent.
I'm in the final stages of completing my electrician course, and I find myself confused (again) by EFLI.
In the textbook provided is this:
see below for each circuit.
Calculate the maximum Zs for each circuit:
Complete the table.
The answers given in the textbook are said to...
Does BS7671 allow fuse rating to exceed cable rating where it is not required to offer overload protection ??
As in the case of a 100A fuse/16mm tails: supplying a CU with just a few final rcbo circuits ?
As title suggests, how many people carrying out EICR code the use of non compliant cables or at least cables not included in bs7671 for fixed wiring such as SY, YY cables.
I see more and more of this type of cabling used for the fixed wiring to anything as a supply to a socket outlet, to a...

As the designer of an installation, anyone put their name against an intended departure from the Regs (120.3)? If so, and you're willing to share, what were the circumstances?
Just wondering how common/rare this is.
Hi, Just need some advice.

So if you come across cabling which isn't in tray or tied up or Round band up - would you leave it or fix it?
Does it say anything about what you need to use to...

Hi Im in the panel wiring industry at the moment and was asked if I have to put voltage supply label next to isolator on the front of the control panel or will a flash label with danger hazardous voltage do? I cant find anything in the regs.
Thanks in advance
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
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...
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...
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...
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...

End to ends = 0.78, 0.78, 1.6. R1r2 = 0.61 (spur).
ZS = 0.66!
BS7671 recommends a max of 100 square meters which using 2.5/1.5 = an r1r2 of...
Hi guys, after some guidance, gonig to be doing an Eicr on a Canal/Barge... anbody ever done anything to do with installations on this? Anything in the regs which i need to be looking at? Everything needs to be RCD? Earthing arrangements etc
I occasionally come across reasonably sized ( not for some of you , I know ! ) star delta motors that have been run in 2 x 3core swa .
Now after looking in to this in the past , it has been suggested that as they tend to be only on motors up to 30kw or so , and as the loading per phase will be...
Hi I'm doing my nic eic domestic installer, I've done my big job of rewire all done and tested. Now I've got to do a small job I've fitted a new socket which is RCD protected but the main tails from meter to the CU are only 16mm does this mean I will have to change them for 25mm as you do when...
