    AM2 questions and queeries 2017

    To expand on what Zdb said the connections are in the switch ie two core from the board to the first switch, line to common then 3 core between three switches, neutral from the board connected to grey and the other two used as strappers from L1 and L2 through the intermediate switch and from the...

    Is a keyswitch required for HMO emergency lighting?

    Yep, I think you might be right on that one, I've installed many emergency lighting systems in the past but never designed them. I had no intention of carrying out the work before I was fully confident in what I was installing, that's why I came here for advice. If the advice is buy BS5266...

    Is a keyswitch required for HMO emergency lighting?

    I was assured that you can retrofit emergency lights into an installation wired as I said, is there any regulation you can give me that contravenes this? I'm really struggling to find any information about it hence asking the question here.

    Is a keyswitch required for HMO emergency lighting?

    Yea two core as in permanent line from the board, looped through the fittings and spurred out to emergency fittings. In a new installation I've always installed three core so the test switch only activates the emergency fittings and leaves the others on. In this installation breaking the...

    Is a keyswitch required for HMO emergency lighting?

    Sorry! I was under the impression you could install emergency lighting in an an existing two core circuit and switch the permanent line for emergency lighting tests.

    Is a keyswitch required for HMO emergency lighting?

    Hi all, I'm technically a 'trainee' but in a months time I will finally have all the qualifications to apply for an approved electrician jib card. The first job I will be undertaking is getting a house up to HMO requirements, which are outside the scope of bs7671 so it's all a bit alien to...

    Socket distances

    Hi all, I'm first fixing fancy flats at the moment, started doing some kitchens, I need none less than 5 drawings that all contain mistakes or out of date information, but that's not the point of this post. When it came to chopping out the sockets, I realised that one will be 65mm from...

    Calculating minimun sized CPC

    Thanks so much for explaining this, it makes a lot more sense now! The problem i'm stuck with now is how to prove by calculation the csa I've selected, although all the information you've provided makes sense, I'm still going to need a PFC to put in my equation, I'm thinking assuming a Ze would...

    Calculating minimun sized CPC

    Cheers mate, that does make sense, but surely once in operation a pcf in the region of 0.5kA could flow, does that not make the calculation and hence conductor size incorrect?

    Calculating minimun sized CPC

    Thank you all for taking the time to answer, it's gonna be a couple of days till i have the time to open the regs book again and have another wack at it. I'm going to have to make an assumption somewhere as no information on protective devices has been given other than the circuits are protected...

    Calculating minimun sized CPC

    Hi all, just working through an assignment at the moment, got everything done other than two questions worded "select an appropriate minimum sized CPC and confirm your selection by calculation". I've already calculated my tabulated current, volt drop and live conductor size for each question...

    two day trial on Monday

    I spent two years doing my level 2 and working in another sector, in the year I've been on the tools I've learned magnitudes more than I did one day a week at college. If you want to become an electrician you don't want to wait any longer to get some experience, IMO. Even if you only do a...

    Real Life Customer Enquirer

    Nice one! Yeah the 0.05 I was talking about was for the bonding conductors, I thought supplementary bonding was no longer needed with the 17th edition, I wont be forgetting the 23,000 figure anytime soon. Surely plumbers replacing metal for plastic in the property often changes the necessity...
