240v outdoor plugs/socket regs or guidance for industrial work areas

Can someone point me in the direction of regs or good guidance relating to outdoor use of a 16a commando type socket vs 13a standard outdoor domestic socket in an outdoor industrial setting. We have an electrician who is arguing that because of rcd protection the 16a blue sockets are overkill. My view is the 13a plugs/sockets are dangerous in the wet - where the socket has little ip rating once the cover is opened. I’m struggling to find good guidance that supports my arguments.

    • Varying product designs in compliance with either BS1363, BS546, or Walsall type A & B pin configurations
    • IP66 ingress protection rating
    • Designed primarily for installation with metal conduit systems

    Never, say never.

  • A potential downside of the metal range type IP66 BS 1363-type sockets is that they may be used with a plain standard BS 1363-1 plug, which defeats the IP rating.

    The BS EN IEC 60309 series plug and socket-outlet are always at least IP44 when mated.

  • Very true, my Dad had a similar metal plug and socket set installed on the outside of the house we lived in over fifty years ago, but in reality any 13 amp plug could be used in the socket.

    That was initially okay, because it was only used for gardening, then the fish pond pump was plugged in on a semi permanent basis without a proper IP rated plug.

    They have been available for many years, but have fallen out of general use.

    Remember though, fifty years ago most UK 110 volt site tool plugs had replaceable fused pins, we do have a long tradition of fusing plugs in the UK.
