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?

    As 2400 asks - are we talking CEE 17 (industrial plugs & sockets to BS EN 60309 - BS 4343 of yore) or CEE 22 (BS EN 60320 / "kettle connector")?


    Certainly a 19" horizontal or many U vertical unit of tens of BS EN 60320 outlets mounted in a rack and connected via a flex to a suitable plug & socket is bog standard PDU arrangement in the UK (as elsewhere). Some may have some fuses or circuit breaker built in, but many don't - where they do it's more a matter of providing some discrimination (keeping the other servers running, or at least restarting quickly, when one PSU goes pop) than safety.
