Why so? >

Because running the circuit smack bang on it's rated current means that the MCB\fuse will overheat and/or keep tripping\blowing all the time. You always use the next highest CPD available, if you have a circuit current of 14A you use a 16A CPD, if the circuit current is

16A you use a 20A CPD.

Yeah, but your shower would have to be on a very short piece of wet string to be pulling its rated current anyway ;-)

Well yes, but that's the way it's done so there...! If you were to actually calculate the circuit current and size CPD's acordingly you might get away with a 45A circuit protecting a 10.8kW shower in some circumstances but in practice, experience and best judgment are usually used.
