    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 ?

    The difference between a registered scheme & standard bs7671 condition report

    Whats the merit between a niceic/napit/elecsa certificate vs a standard bs7671 certificate (available online) for a condition/periodic report? Why join a scheme when its not statutory?
