I've spent the last three years learning this stuff and this chuffing bit of it is the only thing I can't get my head round!
I'm OK with the theory of a Faraday Cage, and totally understand why you need to bond in certain areas, but what I can't work out is this...
1) If all CPCs go back to the CCU anyway, why do you have to connect bonding at a CPC connection at a point in the circuit, and not at the board?
Surely it makes more sense to terminate a 4mm bonding cable at the CCU rather than stuff it into a lighting termination designed for the CPC of a 1mm or 1.5mm cable...
2) and, rather than doing this , is it acceptable to break into the circuit using a JB and terminate the bonding there?
3) Is it 'good practice' for the Bonding to be an unbroken conductor, or is it in the regs? (can't find it...)
If anybody knows any publications that actually explain the practical steps in bonding an installation (rather than going through the same Faraday Cage stuff a la Scaddan etc.), please let me know!
