hi all
come across a new build commercial office where radial circuits feeding electrak power track was protected by 32A RCBO at dist board and the electrak tap off leads terminated into RCD under desk sockets
why install RCD sockets when circuit is protected by 32A RCBO
is this install correct or wrong

Nope, totally fubar.
