    Meter tails protection

    Ian no it doesn't. The 16mm tails have been terminated onto the supply side of the RCD + 60947-2 arrangement. There is no RCD protection provided to the 16mm tails. As the 16mm have been terminated with the 70mm supply tails from cut out fuse. Another RCD will have to be installed with a 4...

    Meter tails protection

    Thanks for the reply Ian. No I don't mean back up protection. I was attempting to refer to the requirements in reg 433.2.2. I have herd of back up protection and it's good to learn how to refer to what you mentioned.

    Meter tails protection

    Thanks gents, I can see that regulation 433.2.2 permits this setup. Would have been nice if my office had just said look at this reg. It's one thing someone telling you it's okay. Better to read it in black and white. What about the neutral bypassing the 63A 60898 though? My thoughts are that...

    Meter tails protection

    I work with temporary electrical installations to construction sites at the moment and have a query related to supply arrangements. The supply earthing sysytem is a TT type. The main cut out fuses I've been told are 200A and the supply tails are 70mm in a three phase arrangement. These 70mm...

    design software

    Thanks for all the brilliant comments. I'll take a better look at ElectricalOM and look for some tutorials for it too. I liked the simplicity of SmartDraw but when I learnt it was American I thought there would be a clash with practicalities.

    design software

    I'm an experienced electrician who has recently passed the written exam of the level 4 NVQ design course. I still need to complete the design portfolio but this is not what I'm here for. I'm looking for some good software that is free if possible but not essential to use to design and present...

    Thank you for all your posts. Electricians forum is truly a brilliant resource for electricians facing the challenges of preventing harm coming to persons, livestock or property.

    is it up to the customer what protective device is in his installation?

    I've been asked to install a shower unit in a clients house and he only wants me to change the shower itself. The consumer unit has BS3036 rewireable fuses and no RCD protecting any of the circuits, including the existing shower circuit. He has already bought the new shower and only wants me to...

    do you use the multipliers from tab 13 in OSG when calulating volt drop?

    Cheers gents I thought what the tutor had taught was wrong. Can't believe it! Feel like asking for my money back. He'd even put the formula on a handout he gave us. Been looking at the books trying to wrap my head round it. I see it now in Appendix 4 table 4D1A (for example) conductor...

    do you use the multipliers from tab 13 in OSG when calulating volt drop?

    I've recently done a C&G 2396 Electrical Design Course and unfortunately the tutor who taught the course did so for the first time and in my opinion didn't do a good job of teaching the material. I'm now doing my revision for an exam this Thursday and trying to make sure all the formula I use...
