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.
IT cabinets are 3 Phase and I dread the thought of an IT Technician interconnecting the power to dual fed Servers for obvious reasons.
I totally agree with Mike and Graham - there's absolutely no problem mixing phases on modern equipment (we did it frequently with dual-PSU servers - typically one from mains and the other from a UPS so there might have been more than 400V between them!) - there's not even any need for a 'Danger 415V' sticker any more - since Uo is still only 230V.
