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

    Agreed RB, I did say caveats apply. Providing non-standard sockets is not an automatic get out in 7671 2018 as it seems to be in ET101 2008. 

    By the way, purely out of academic interest, I have only just recently began to identify differences between the two sets of regulations. Both are HD based but it is interesting to note the difference in the various omissions, inclusions and approaches in both documents. I am not sure which, if any, of the regulations in ET101 are SNCs but in relation to the OP, it would seem that the intention of both national standards is that non-RCD protected circuits supplying sockets of standard construction are not acceptable even if the intended use is specifically for IT equipment unless other measures are considered.
