While completing the Elecsa certificate, it asked for the nominal current rating and short-circuit capacity of the primary supply overcurrent protective device. The system is a TNC-S and there is nothing written on the fuse at all to say what rating it is. Also it is riveted and it cannot be open to check the fuse inside.
Do I leave the Nominal current rating - Blank?
And how do I measure its shortcurcuit capacity using a Megger 1552
And are we allowed to isolate the supply to change the consumer unit by removing this fuse . I am not too sure where I stand as there is no other isolating switch.
Thanks.
