RCD protection in an IT run office

Former Community Member
Former Community Member
Jolly good morning all,


I am currently carrying out an EICR for an IT based company in their head offices.

Looking at the 12way  3-phase distribution board, I can see there are multiple ‘Office Sockets’ circuits labelled up on 32amp MCB’s and not a single RCD in sight. 

To my knowledge, the use of RCD’s is perhaps not required in this type of environment, but just wanted to check your opinions.


Many thanks you’s and I hope everyone is having a splendid dayV?

    ....The easiest way (which I have not seen anywhere!) would be to have a garage size CU by every desk with an RCD/MCB/RCBO feeding a number of local sockets. The feed to all these could be a high current ring, providing the high integrity Earth and power of whatever is needed. Fairly easy to install, even for island desks with a floor trap, and very fault resistant on any plugged-in equipment. I wonder if anyone else has seen this or any other ideas?


    Something like Mike's link in the first reply to this thread? Electrak Floor Box with RCD & 2 x Low Noise Twin Switched Sockets JP2532 Tap Off (CR4413) | CEF he cunningly embedded the link, which i haven't worked out how to do on this forum, so people might have missed it.
