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.
They are defined as "couplers" .... in Reg 553.2.1
Saying that couplers must comply with BS EN 60320 logically isn't the same as saying all things complying with BS EN 60320 must be couplers - that would be like saying since sockets must comply with BS 1363 then all things complying with BS 1363 must be called sockets - and thus you couldn't have a BS 1363 plug. (Or the classic example, since tables have four legs, all four legged things must be tables).
On a wider note, I'm getting less and less happy with the definition of a socket needing to be attached(?) to fixed wiring. There's no definition of fixed wiring (I could see that it could either be wiring that's not free to move, or equally, wiring that can't be readily unplugged from the supply and relocated). If following the example of 'fixed equipment' the former might be expected, but is there really a significant difference between a wall mounted socket and one of these? https://olsondirect.co.uk/4-way-13a-switched-socket-suspended-service-unit.html
