Hi all
This is a college work question, I'm afraid! I know you normally send students away with a flea in their ear, but I've been flogging through the regs, books and the internet and have not got very far! I've never seen a TT installation (city girl) let alone installed one, so wondered if someone could give me a quick 'checklist'.
I need to know the precautions that need to be undertaken when installing a TT system. I know about suitable earth electrodes but am stuggling a bit with maximum Ze's, rating of RCD's and when to use them (different ratings for different circuits??)
Any pointers would be much appreciated
