    RCD test button

    You doing it the last, because in real life the rcd is not pressed quarterly as it should to move mechanical parts inside it as they can stick, and by pressing it before time tests, you loosen the mechanical parts and time tests after that is not credible, as in real fault situation there will...

    Block of flats. Max Demand

    Sorry Richard, where this 100A fuse came from? In previous post you came to 170A per phase. Is it because there is no BS 1361 and BS 88-3 fuses higher then 100A? What other options DNO have, perhaps BS 88-2 160A? Or is this only for motors and inductive loads? Thanks.

    Hi Richard, thanks a lot, all that detailed sharing of experience I was waiting for, invaluable, you are my top spark now. Sorry to be a pain, just a little clarification again. When you say I was close in option 2. I did have 53A per flat, but taking all flats in consideration I applied...

    Block of flats. Max Demand

    Hello, thanks for replies. Yes I do understand what you Tony and Archy are saying, it’s easy to say when you know exactly what you use and how much. In my instance I needto design an adequate system, where I don’t know the exact load, what I knew I did put it in the OP. What I know, is that...

    Block of flats. Max Demand

    Wonder if I can get some guidance, on max demand in block of flats. It always was hard for me as it always comes to massive demands, and I red here that it all comes with years of experience and that it is like an art. This is first bigger project I am taking on. So please don’t shoot. I need...

    pfc

    When you say the whole consumer unit, do you mean with all PD in it, if that’s the case non complies as far as I understand, because all PD are 6 kA maybe sometimes 10 kA, but definitely not 16 kA. And then what code would you give on EICR, C3 or C2, I would see it as a danger under fault...

    pfc

    That’s right and I knew that. It’s just I thought if the circuit is really short, let’s say, a radial socket in next door cupboard and to add R1+R2+Ze (0.03) the PFC from that could be over 6 kA, as most MSB’s are this size in domestics, but then I imagined the R1+R2 as low as 0.10 ohm and...

    Sorry Telletrix, Can you explain that. So where I should take the PFC readings to make sure that consumer installations equipment complies?

    pfc

    That would be really low Ze, in region of 0.03 ohms, is the premises right next to distributor’s transformer? And is it domestic property?

    Hot Fuse in water heater spur

    Not sure about regulation, but in OSG it says, any fixed load above 2kW should be on its own circuit. I think the key word here is SHOULD not MUST, thats why it is open for interpretation.

    Exam question help

    re: Exam question help By the time you will get to do the circuit Zs, you will know which the furthest point is in a radial circuit. For the ring obviously you test at each socket. Unless you only perform the Zs tests to confirm that the installation safe, and believe me I know some so called...
