    hi, can some one tell me, when making a ring main for sockets how many amps do you have per socket. eg if i have 7 double sockets in a ring main, what size should the fuse/breaker be in the c/unit.

    another question. whats the regulations on how many double sockets there can be in one ring main. Could some one tell me or point me in to the direction where i can find this info. Thanks.

    32A mcb fora ring main in 2.5 T&E.

    An infinite number of sockets may be fitted, as long as Zs can be achieved.

    smith you should have a 32 amp breaker.And you can have as many socket outlets as you like,as long as the ring final does not exceed 100 sq metres.

    cheers for the reply those who answered the question.

    Reason i wanted to know how much you would rate a double socket is if i have 2 sockets in a ring i don't really want the current to reach 7000 watts before the breaker tripped

    Agree 100%. No disrespect to the chap but asking questions like that shows baser knowledge to say the least..perhaps he could study up and then have a rethink on his question..and then there are the practical issues and sorry to say Part P..if you are not going that route at least follow BS 7671 to the T.

    "Reason i wanted to know how much you would rate a double socket is if i have 2 sockets in a ring i don't really want the current to reach 7000 watts before the breaker tripped"

    The 32 Amp breaker in the Consumer Unit is there to protect the 2.5mm^2 T&E from over current. The fuse in the plug protects the item that is plugged into the socket and those should be rated to the lowest acceptable value but often the ubiquitous 13 Amp fuse is used as a cover-all.

    This is a wind-up, isn't it? If not then sinewave is only acting in the interests of public safety.

    I reckon it's a wind up. Look at the text in the post.

    c/unit = Not the sort of terminology Joe Public uses. Fuse box would have been more convincing.

    What's the regulation on how many....
    Again not really convincing. Most people wouldn't think there is a regulation.

    So come on, own up who are your really????

    It's a wind up JP., it is actually too blatant.

    X must be on holiday..probably sunning himself in some tropical paradise somewhere studying up on yet another aspect of electrics..however despite that.... the safety aspects of this forum are being monitored..which proves it is pukka. I think there is more then one administrator for this site..X being the man in charge so to speak.

    From what I see there are several.and it would be wrong to name them so that will not happen..have noticed that they reply in the same ilk as X..but with not quite the same panache so to speak..who can copy X's panache? answer.. no one.

    its not really rocket science 32a on only 2 sockets? I would use a 16a.
    How can you have any respect for a regulatory authority That says ok plastic consumer units catch fire we will now use metal??? what about the thousands already fitted? If that was an air bag in a car they would all be recalled and replaced free of charge.
