Use of RCD protection in industrial and commercial installations

Andy
Hello All

We all know the benefits of RCD protection and how the regulations are changing regarding domestics. I am constantly being asked if RCDs are required for normal switched socket circuits in industrial installations apart from the obvious use of RCDs for areas likely to cause a reduction in resistance (sockets that could conceivably be used out side). So are RCDs required for general office circuits, for dedicated IT equipment (computers etc), work areas such as clean dry packing areas and so on.


Given RCDs require testing regularly and the results recorded which causes disruption to production equipment, IT equipment, Data centers etc are RCDs really required especially if they are installed within steel conduit or steel trunking on walls or under floors?


Any advice welcome

    If a particular circuit is critical for safety services or business functions, surely socket-outlets would not be the preferred option, to prevent accidental "unplugging".




    There is the possibly apocryphal story of the ITU deaths on a Tuesday morning in Bed 3. Clearly, deaths are not unusual in ITU. In this case, audit revealed that there were more deaths in Bed 3 than the others, and more on Tuesdays than other days of the week. Eventually, investigations revealed that a cleaner had been taking one of the plugs out of a socket so that she could use her floor polisher. When the alarm went off (obviously plugged into a different socket) she got out of the way and plugged things back in again. Nobody noticed.


    I doubt that it is true, but let's not allow that to spoil the story. ?
