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.
