    Design me a circuit please

    You asked for it, James. Aha! No, in all seriousness, thanks Marvo for putting this up, really appreciate the time. I couldn't answer this off the cuff, but I'll try and return over the next day or two with my effort, as laughable as it may be.

    More questions, fault finds, fault pictures, games etc.

    While I appreciate your stance, in my opinion that only increases its value; I'd love to hear exactly what the the issue was. See. Now I'm curious to hear what elements of that fault would serve to confuse.

    More questions, fault finds, fault pictures, games etc.

    I'll be honest again, James, I think you might be asking a little too much of the individuals who volunteer their time to this area of the forum. However, I do agree, I would love a steady stream of fault finding questions! And I know you are actively employed, so do be sure to share your own...

    Lighting - wiring to switch FIRST

    I don't mean to steal Baker's thunder on this, but I have a couple of drawings from last year. This, if I've read correctly, is what Baker describes, which is exactly how you'd wire it in 3C + E / w/ a strapper - This is an alternative method, which actually uses one less conductor, and...

    Lighting - wiring to switch FIRST

    Apologies, James, either I didn't read your post completely, or you added a little more to that. Then it's to your credit, then. I needed the second year to build my confidence with steel conduit. By which point I had already completed a variety of singles 'clips', so the wiring would not be an...

    Lighting - wiring to switch FIRST

    Thanks for that James. I thought the format of the 2330 L2 was that students undertook the 206 practical assignment towards the end of their second year. That your tutors are happy with your progress is to your credit, of course. But when asking such questions about wiring in singles, it does...

    Lighting - wiring to switch FIRST

    Are you on the first year of the 2330, James? If I recall, and it wasn't that long ago, we we never undertook an end of year practical assignment during the first year; we had a number of practical 'clips' in a binder which every student worked through. Usually, what began to feature during our...

    Lighting - wiring to switch FIRST

    I'm surprised you ask, in all honesty. Via singles, one can supply or loop out to the next switch via the common terminal. Have you had a go drawing a circuit diagram?

    Useful PDF's for trainees

    Okay. I've got around to pooling together some useful bits that now exist in two separate folders on our shared Google Drive. I've opened these up for those interested. Education - https://docs.google.com/folder/d/0B8-nHrT9MMRQd2RaNEhSZ3JTcEE/edit?usp=sharing Electrical / Electronics -...

    is anyone here as bad as maths as me?

    You'll have to share your secret, Baker. Or is it such that if you told me, you'd have to kill me? Haha. A great memory does not amount to intelligence, it is a fallacy. Having the capacity to learn and the discipline to consistently apply oneself is far more important, as the ability to...

    is anyone here as bad as maths as me?

    Your honesty is refreshing; I think it takes a certain strength of character to admit your weaknesses. There is one chap at college who is, if you'll excuse the turn of phrase, absolutely **** hot with the practical / fault finding side of things, but does struggle with the theory. He has had...

    IR Test

    Directed at Trev, then, why could one just not reduce the test voltage to 250Vdc?

    IR Test

    Funny that, we are going through T & I at college at the moment and this method hasn't been discussed. To short L and N only seems practical if you've already proved that the IR values between all conductors are acceptable, and no dead-short exists between L and N. I assume this method is used...

    Fault Find #7

    Thanks for that Paul. I had envisaged a R1 + R2 plug top tester, like the one Kewtech make and that I link to below. From your description it doesn't sound like the product, so can you provide a link to the one you used, for clarity? Kewcheck R2 Socket Adaptor - R2 - Test Without Removing Wall...

    Fault Find #7

    Haha. No, none taken. I appreciate the honesty. I've tried to condense what I've written above, but the question remains; I'm not sure I can reduce it any further without attaching a drawing. In fact, I may just go ahead and do that...

    Fault Find #7

    Another question, as while this sort of thought-exercise doesn't have any value if you are too explicit, I'm not sure I quite understand you. So you've metered the socket-outlet, and with reference to 0V you obtained the readings above. What you describe above, does this still assume you are...

    Fault Find #7

    Thanks Paul, these are always welcome! Could you clarify the above by introducing each with a reference; live is at 0V in relation to what? N is at 244V in relation to what? It appears too simple to just assume the socket-outlet has been wired incorrectly. More details are required, I think.

    Cable sizing

    That is a great guide from Napit, Floody, thanks for the link. It is a little dated though. I think the key phrase is included in the side bar, the 'correct method'. With experience one is able to assess and estimate with some precision, intuitively. However, if the 'correct method' is observed...

    Application of Diversity

    That is where the confusion lies. I understand why the correction factors are applied, and that they relate to CCC. While the article is to the 16th, the procedure as listed is how we've been taught. Is that not the correct approach? http://www.tlc-direct.co.uk/Book/4.3.9.htm
