Hi all, (not the standard domestic setup for me)
-3 phase overhead supply TT. coming in via 3 200amp fuses (not sure what type so unsure what to write on cert) any ideas?
-Then goes to large rusty switchfuse (see pic). Bs3185?? Earthing conductor straight into concrete.
-Fairly large swa cable (not sure on size)(any ideas?) from here to 3phase board about 100mtrs away which also feeds swimming pool etc.
I want to install some lighting from this board.
My questions:
1. what r the supply fuses?
2. Testing ze at switchfuse (do I just remove the top brown guard?) or just settle with zs at board down stream.
3.whatsize is the 4 core swa (cpc is the armour)
4. what size is the earthing conductor (shall i calculate by measuring and applying pi etc
-thanks
