RCD protected socket outlets in offices

Hi All,I work for an NHS trust. One of our buildings has just had a major refurbishment including acomplete rewire….We now have floor boxes feeding network snd power to most desks and thepower sockets are all twins with a built in RCD. A contractor who was fitting monitors to the desks was of the opinion thatthere was no advantage in having these. (And a disadvantage, as people will accidentally hit the test button andcut the power to the desks). I wondered if maybe they are needed in order to disconnect quickly enoughin certain fault conditions?Or if by having 30ma RCDs at the desk, it it allowable to feed them withsomething with no / “less” protection (a slower “blowing” RCD or one ratedat say 100ma). Or are they over(non)kill?Or something else?

So a socket RCD would be pretty pointless then, and a waste of money?

That may not be the case.

The OP has not given any relevant details of the installation. But to be fair he only passed on a comment from a contractor[1].

There are no details of what cable was used to supply the floor boxes or what installation method was used.
