Hw many computers for no RCD

[Fazz711]

We have to put two new tower sockets in to a office at work.
At the moment we have two towers but four sets of four desks.
The two sets of four without towers are fed via extension leads hence the need for two new towers.

I have been told by our tech guy we aren't fitting RCBO on the two new circuits.
There will likely be 16 off sockets on each tower but only four will be used for laptop stations.

The other sockets will be monitor phone and a spare for each desk.

I still think like all the other offices with computers they still need protection.

We have two floors of large open plane offices and several sub offices and they are all covered by RCD including the other towers I think.

So what do the real experts think RCBO or not.?

Well after being assigned the job again after new bits arrived it now seems tech guy agrees with me and he has a RCBO.
Also found he has everything for a ring not a radial.
After questioning him as to which he wanted radial or ring as I was originally told radials he now wants ring.
After another quick question he has spat his dummy and said to leave the job and he is getting one of the other engineers to do it.

So thanks for the advice to everyone who replied

This is why it would have been easier to get a spark in at the beginning. The job would have been done by now.

Parts only arrived yesterday so could have only been started last night.

He should use a DB and D/P Rcbos feeding radials, a single rcbo feeding all those SMPS is bound to have lots of earth leakage.

At the moment the desks are fed from two existing towers with an RCD each in the DB.
8 times the amount of computers than will be on the two new towers.
Never been a problem.
The new towers are being fitted to do away with extention leads feeding the desks furthest from the towers.
