PV Solar DC Surge Protection Device SPD Installation Wiring Diagram - 1 String Input 1 String Output 

Thanks for your video please I missed out on how you connected from DC fuse to mcb to the output did you loop wire from fuse to the upper side of the mcb or you loop to the down terminal of the mcb ?

why do we still need a fuse when there's the mcb?

why this SPd also has PE ? so have to connect ground and PE ??

Thanks COOP ...
