Use of 16 and 32A radial sockets in data centres

Russell Bulley
Radial sockets seem to be detailed in BS7671 appendix 15 as domestic only. Are there any regulations providing guidance for the above?


I was quite surprised to see strings of IEC type sockets CEE arrangement (with earthed pins) linked together with a single radial feed from another socket, of course all unfused. The whole are protected by 20A RCBO’s. Generally the arrangement is as the left hand side of fig.15b, without the junction box. I assume this is standard practice in Europe?

    Well, typically Graham, all the racks holding everything are Earth via bonding anyway so the protective conductor current is perfectly dealt with. This is largely brought into play due to EMC considerations, but obviously works equally well for the safety too.  You would find it very difficult to find much PD in a typical server environment. We have been told that it is this kind of place in the OP.
