    Application of Diversity

    http://www.electriciansforums.net/electrical-forum-general-electrical-forum/72952-application-diversity-standard-circuit-arrangements.html Okay. It didn't really work, haha! I'll bump it Sunday or early next week.

    The price of experience

    I'll be honest, that is massively disheartening. I know you haven't posted up here looking for sympathy, but I do hope your situation improves and wish you every success in making that a reality. As a student I'm not really placed to offer you any specific advise related to the industry and how...

    Application of Diversity - Standard Circuit Arrangements

    Will do! But where do I put the dog ****, and can I apply diversity to that?

    Application of Diversity

    I appreciate it isn't particularly concise. I've tried to trim it back for the main forum, but it doesn't appear to be going too well over there, aha! It's just trying to be precise with my terminology. What you've said (8000w/230=34.8A) would be Ib, is that right? I believe the step after that...

    Application of Diversity - Standard Circuit Arrangements

    Hi there, this is a question I originally posted in the trainee sub forum which has been a little quiet of late. I know more traffic flows through here, so I'd be grateful for any corrections. In specific relation to the standard arrangements of final circuits in accordance with Appendix H in...

    Application of Diversity

    I appreciate the comment all the same, Marvo. I was actually tempted to post it over on the main forum as I know traffic there is a lot higher. Having mused over it this evening, I'm still not confident my interpretation is correct.

    An explanation of Phases?

    Having a bit of a night of it tonight, I do apologise. Quite a simple observation has left me wondering. If we consider a 45A single-phase load and a balanced 45A three-phase load, star, assuming both with a purely resistive load, does the maths resolve as follows? 45A SP - kVA = (UI x PF) /...

    Application of Diversity

    I will drop this here, also. I write this with reference to a previous diversity exercise we completed at college and the design of a circuit supplying a cooker rated @ 13kW. I = W / V = 13000 / 230 = 56.23A. After the application of diversity Ib resolves to 23.87A, so In = 30A. Pulling a...

    Application of Diversity

    Okay, I'm going to drop my other questions now. Still curious to hear about my first as that impacts what I'm about to ask. Anyway. Assuming that one does not apply the various correction factors as described above... In specific relation to the standard arrangements of final circuits in...

    Application of Diversity

    Just a quick bump on this. Any comments would be welcome.

    Conduit Bending

    Perhaps, but I doubt the OP has a bending machine at home. Thanks Marvo. I remember one of our tutors explaining the formal method of produce concentric / segment bends. I remember thinking at the time that doing it 'by eye' was surely impossible, and that without knowing the method, you'd had...

    Conduit Bending

    There is, isn't there! Although they refer to the ETCI, Electro-technical Council of Ireland, each rule appears to align with BS7671 to some extent, and component / accessory parlance is identical. I would, however, err on the side of caution and cross-reference for accuracy before acting on any...

    Conduit Bending

    I found the document below a useful reference, particularly with the explanations on how to approach 30 / 45 degree sets and bubbles. From page 27. http://www.ecollege.ie/site/liu/electrical_notes/LL231.doc

    Application of Diversity

    In fact, in light of a recent thread I do have a question. There seems to be some conflicting information concerning the sequence to derive Ib. From a number of different online sources, actually. It has introduced an element of doubt, so I'd be grateful for confirmation and / or a correction...

    How to tell if its Ac or DC... And why would I need to know?

    No, I appreciate that and can see that is what motivated you to post. I'm glad you took my response in the right way. I try to be proactive and relatively self-serving, and least attempt to answer whatever question I might have via the literature I own, via Google or by using the search tools...

    How to tell if its Ac or DC... And why would I need to know?

    Don't you think that is a little presumptuous? How could you reason what others will want to know, but will not want to ask?

    How many regs

    Just chipping in. Well, Part M of the Building Regulations is fairly fresh in my mind. But 553.1.6 appears to cover it. Ay. Ib < In < Iz. Assuming the worst case scenario via the specification of CAT5e, an AWG of 26 translates to approximately 0.13mm2. Even if I knew absolutely nothing else...

    maintain building structure homework

    What Marvo describes is covered by 522.8.14, and is neatly detailed here. http://niceic.com/Uploads/File3777.pdf Given the question, I'd expand on that and say Part 527 is a little more relevant. To the OP check section 1.2 of your OSG and consider the Building Regulations. Why you are...

    Part B Building Regs

    Apologies if I'm stating the obvious; as far as I'm aware, the specific guidance is beyond the scope of the OSG. http://electrical.------.org/books/guidance-notes/electricians-guide-part-p-2nd-edition.cfm http://electrical.------.org/books/guidance-notes/fire-detection.cfm
