I'm confused about measured zs on the actual day: for the heating (are we just going upto the fused spur) and for the 3 phase socket, is there an adaptor plug available ? According to your understanding its all calculated zs, no actual measurements with live testing with the tester. Thanks again adrian much appreciated.

I was trying to understand why the C32 coming from a consumer unit being looked at as a distribution circuit, I was making the assumption that all circuits leaving a consumer unit would be a final circuit, but there is nothing to say that you couldn't have a 3 phase board feeding different consumer units I suppose.

hola, muchas gracias. Thank you very much I was quite lost and I will have my exam soon. I have some industrial experience. I was thinking today why in the consumer units in UK you dont use type A RCDs since the increase of electronic devices that can trip the normal RCDs.

I am not very observant! you do use type A ( the RCBOs ) . I was just talking about the split boards. I got confused because in France and Spain they use to have split fuse boards with a type AC and a type A for specific circuits. I got the guidance note 3 and I am studying hard. I got an old multifunction fluke to keep going for now. In france and spain the electricians do not do test and inspection, when you finish the installation you take a couple of measures if you want and go home. You call the ' CONSUEL' in france to come and check the installation, and not allways, when you change your meter for example.. just the basic checks and the guys are not even electricians , they have a very specific training for doing this few measures. I used to do whole large commercial on my own when I moved to a rural area in france so when I came to UK I was very surprise, I could not do much, I didnt know how to do proper testing, I only knew the TT system the only one in france, I was use to all pvc materials , I mean all is pvc ! , a funny thing is that we do not do bends in france hahaha we put flex inside conduit and leave it exposed in the bends , the conduit is just a mean of installation ,not really protection. Of course I am not talking about super installations as a big train station or so, that is different ...and also the regulations in france are actually just a guide, well more or less, everything is so harmonised that you always do the same, I understand now why , in UK you have all this historic big houses, millions with old ( but very good) electrical installations that need to be well checked, anyway........so I started from the beginning here. I met some british electricians in france on sites doing other non electrical jobs and I used to tell them: come on man! you come with me and I get you a job right now and they didnt want to , I met a couple of them..and now I understand why , because they thought the electrics in france were as complex as in UK or rather they thought to be electrican in france you needed the same competences as in UK. I didnt understand why they were shy because they had worst jobs and my company was looking for experienced electricians. I miss the cheese and the bread..ok merci encore Adrian bie ( sorry! very long).

I have to do a resit next week and I am not sure on a few things. On the electrical certificate do i tick new installation or additional to an existing installation ?Plus I remember when I did the Ze test, the result was 0.78, that’s above the 0.54 allowed for a type c RCD. I have been told to write on the remarks that the ring is above the Zs permitted but it will meet the standard as it states on table 41.5 as the maximum for rcbo is 1.667 ohms. Is that correct. ?

What does guidance notes 3 tell you, as that is what you will have on the day, and what the assessor will be marking you against. 👌

Hi Adrian, you must be exhausted after that 😀 Thank you for your generosity - I learned a lot. As always, I have a few points I would ask you to clarify please. I got rather confused on the Ring FC testing. a) I think you just made a mistake when you said end to end ohms were 0.2 but then you calculated R1:R2 as 0.01 instead of 0.1 You also put these figs in the test schedule. b) What I really didn't understand was you said that once you calculate the R1:R2 you should confirm the fig. at all sockets and C.U. How can you do that? the ohm meter will always give a reading of R1:R2 x 4 at all points (assuming the figure of 8 linkage) c) As for the spur - I would suggest that all you can do is to record the Increase in resistance from the std socket on the ring. Then add the increase in resistance (undivided) to the calculated R1:R2. It might be worth explaining that the R1:R2 for Rings is different to that of radials in that that it is only a theoretical concept used for testing to confirm the integrity of the ring. The true R1:R2 value will vary at each point depending on the lengths of the 2 conductors (in parallel) connecting the socket to the C.U.. (as shown by live Zs testing) But that another story. d) On Zs - I missed any mention of C(max) correction factor 95%. But is see that this is already built into the tabulated Max Zs value. Also, I may be a stubborn old fool, but I don't understand why we can't insert the Max permitted Zs value WITH thermal correction, into the test schedule. This would make more sense and make it easier for less well trained people to at least read and make sense of the test sheet. If correction factors change in the future, how will the reader know which factors were applicable at the time of testing. Just seems ridiculous to me. e) Re disconnection times - you gave the impression that a 32A breaker needed to trip within 5 secs. Surely; as it's not a distribution circuit, the required max trip time is 0.4 secs. on a TN supply. f) Finally 😀 Just a suggestion to help learners - you mentioned Doubling the Pfc test result on 3 phase supplies to give the value to be recorded. I just thought some learners may not understand why. You could say that doubling is an easy approximation of multiplying by the square root of 3 and this is necessary because the voltage between phases is much higher than between one phase and earth (measured). Therefore the current pushed through the cabling will be much higher. Also why we don't do loop impedance between phases. I hope you can put me back on track where I have gone wrong and that I may have helped in some areas re the perception. Thanks again.

@@Pure_electrical_training Yes I just watched yr vid on RFC testing. That's pretty much how I understood it too. I guess the reason for the discrepancy when testing all points with fig of 8, is all down to the higher resistance of the cpc. Imagine a socket right next to the C.U. The 2 paths for the electrons to follow will be of equal length but NOT of equal resistance. One will be almost entirely 2.5mm and the other almost entirely 1.5mm. Whereas a socket at the mid-point will have paths of equal length AND equal resistance.

Further to my last comment - I just constructed a spreadsheet to calculate the variance in test results with fig. of 8. Assuming end to end of R1 = 3 ohms and R2 = 5 ohms A socket placed only 10% of way round ring will give "R1:R2" of 1.92 ohms. A socket at the centre of the ring will give 2.0 ohms. I can send you spreadsheet if you wish.
