RCD Protection at Data Cabinets

Bob Cowie
I have a Client that will not provide a Risk Assessment to omit an RCD Commando Socket for a Data Cabinet. He wishes to employ a local isolator for the Cabinet, however he is concerned that the PDU Strip that arrived on site from the factory and pre-fitted within the data cabinet would still need an RCD. It is my opinion that the Factory built Data Rack is classed as a piece of equipment and as such does not form part of the Contractor's installation. If the Rack had arrived on site without the PDU strip fitted and it was installed by the Contractor then this would form part of the installation and therefore would require an RCD. Any advice/assistance would be appreciated.

    No, not the couplers (e.g. on the end of a flex) - I mean the "chassis mount" outlets - often incorporated into rack mounted power distribution units (PDUs) in just the same way that BS 1363 outlets are. One example:

    Andy, the BS EN 60320 outlets are not socket-outlets but are known as "interconnection couplers"


    Basically, there are the following:


    • Cable couplers (e.g. for the 6/10 A version, Type C13 "free outlet" connector and its corresponding appliance inlet coupler Type C14; and

    • Interconnection couplers (e.g. for the 6/10 A version, Type E "free plug" and its corresponding appliance outlet coupler Type F).

    The whole standard BS EN 60230 is entitled "appliance couplers".


    Hence my question, should we extend RCD protection to these also?
