    Multi-core neutrals and earth

    I found the regulation in BS7671 314.4, yellow book When an installation comprises more than one final circuit, each final circuit shall be connected to a separate way in the distribution board. The wiring of each final circuit shall be electrically separate from that of every other circuit...

    I just drew this. Not sure if it makes sense or even it is correct. Any feedback would be welcome.

    Good point, thank you. Glad I checked with the forum. Do you know what reg, forbids shared neutrals?

    It is over complicated, I would design it different, but the person who's house it is wants all the breakers in one location.

    Actually thinking about it, You are right. Exactly this situation could occur, you could leave a circuit powered then disconnect the neutral at the termination at the end of the SWA and the neutral from another circuit could become live. Sorry you are right. It could be dangerous. Thank you :)

    That situation could never occur with the design I have drawn

    I know of configurations in which sharing a neutral can result in a dangerous voltage on the neutral. I knew this thread would go down this path. I could draw the situation, can you? If so draw it then explain how the fault relates to this design.

    Apart from the shared neutral being dangerous, which I do not think it is in this configuration, is there any reason why we could not wire it as shown?

    It is more of a parallel conductor design than being a shared neutral in my opinion. The person I am working for is electrically qualified and this is how he said we wire it. I am unsure that is the reason I am asking here. In this configuration it is impossible to get a dangerous voltage on...

    Multi-core neutrals and earth

    Hi, I am currently training to become an electrician. I have passed all relevant C&G level 2 exams along with C&G level 3 inspection and testing and principles of electrical science. I have been asked to help design some garden circuits but been given specific instruction on how the circuits...

    Mirror light from lighting circuit. FCU or isolation switch needed?

    That is a great idea, thank you :)

    Thank you. That is exactly what I think.
