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?

    I hope that this system is not TN-C in which earth and neutral are combined up to the point of use.

    More likely to be TN-S with neutral and earth seperate throughout, or TN C S whereby the neutral and earth are combined in the DNO network but separete in the consumers installation.
