termination of the CPC!!!

sorry mate i was trying to be diplomatic, i'm new on the forum and their has been a few mistakes made in this topic.
as you may know people read on forums and look at the number of posts then beleive everything they say, which is a bad thing.
just because i've been at it for 28 years doesn't mean i know everything, you will find i'll ask some bloody stupid questions that apprentices will know but it may be something i've just taken for granted
termination of the CPC!!!
yes its a learning curve so hopefuly tonight you've learned the new name for the main earth its the 'main protective bonding conductor' the term for connecting cpc's into the earth bar is 'termination of CPC's' and that parts of a circuit which are not used but may become live under a fault condition require 'supplementory bonding' and that i don't generaly ' use the SWA armoured sheath as a CPC'
and finaly i am a pain in the ---

check your regs book page 167 544.1 amend 1 2011 - just remember it was you which said i described it wrong
and always a pleasure never a chore!
what size should the fly lead from SWA earth tag to cpc bar be?
If for instance a 6mm SWA is run in should the fly lead be 6mm?
Or use the adiabatic equation (which has probably already been suggested).If using the SWA as your CPC, size the flylead as per the CSA of your line conductor.
Or use the adiabatic equation (which has probably already been suggested).
Exposed-conductive-part. Conductive part of equipment which can be touched and which is not normally live, but which can become live when basic insulation fails.
Extraneous-conductive-part. A conductive part liable to introduce a potential, generally Earth potential and NOT forming part of the electrical installation.
How can a fly lead from an SWA be supplementary bonding?.....I'ts earthing.
I promise I will never ever,ever,ever pull someone up on this again....honest....if I do please have me shot.
