Does BS7671 allow fuse rating to exceed cable rating

Does BS7671 allow fuse rating to exceed cable rating where it is not required to offer overload protection ??

As in the case of a 100A fuse/16mm tails: supplying a CU with just a few final rcbo circuits ?

Testing to see if this works..

K²S²>I²t

S = (√I²t) ÷ K

Looks like hieroglyphics to me

K²S²>I²t

S = (√(I²t)) / K

think that gave be a min x section of 2.2 mm. (using the virtual 230V and a disconnection time of 0.1 sec.
