18th question.

Hi all, any comments welcome on this one.
Is it still acceptable to have a socket outlet for a specific use not rcd protected under the 18th?
I fitted a single 13a socket outlet recently in a loft space for one of my regular customers, it is to supply a security camera system and the suppliers asked for a socket to be provided. It is supplied from the first floor lighting circuit which doesn't have rcd protection. (16th. ed. board) There is not the slightest chance of the socket being used to supply anything else and I would like to issue a mwc stating that the socket is only to be used for this specific purpose. If it's a major issue I could get back to the customer and arrange to fit an rcbo but I don't really think that is necessary? Thinking now about going back to change socket for an rcd protected one?

    My opinion here will deviate from what is stated in BS 7671, and, for some crazy reason that there has been no explanation of the product standard for RCD socket outlets (and fused connection units) have been removed from BS 7671:2018, so that could require a deviation, me, I'd not worry and fit one, including a deviation if necessary.

    The requirement in BS 7671:2018 is that ALL socket outlets in domestic premises must be RCD protected.




    The current version of BS 7288 actually says that additional protection should already be in place within the installation. The last sentence of the first paragraph of Clause 1 of BS 7288:2016 states:

     



    SRCDs are intended for use in circuits where the fault protection and additional protection are already assured upstream of the SRCD.



     




    Yes Graham, I did look up BS 7288, some time after I responded to this thread, but it had disappeared from my forum view by then so I took at as resolved.

    I feel that this is an error, of some kind, in BS 7288, which has resulted in this scenario, and this upstream requirement is the reason that the standard has been omitted from BS 7671.

    This does need to be resolved by BSi/the relevant committee/JPEL64 to give the industry clarity.

    At the moment devices to BS 7288 are really a device without an application, unless you really require redundant RCD protection to ensure that hopefully one goes and you don't care if the two go out in the event of a fault.
