pblec,

After 28 years in the industry as an electrician, you shouldn't really be having this conversation, ...but You are!!!

And you shouldn't be having it with a guy who's younger than the time you've been in this industry.
 
i have used the outer core of swa as a cpc but that wasn't the question

i couldn't use it as CPC when i first qualified as the firm i worked for didn't allow it and even now i won't - but that doesn't mean its wrong.

i'm sorry but what it does mean is you need to get your head in a regs book and refresh your knowladge a little, its not an insult i've just opened my green book tonight because of these forums.

Read on mate read on. Ive said nothing wrong in this thread and if you think I have prove it with a erg and why,

and you havnt answered my question, what is it called when a CPC is connected to an earth bar because the term earthing doesn't exist?
 
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

And I agree and so do all the old timers out there. We can't be expected to know it all and we don't, it's all a learning curve.
 
I think the answer to the original question is, just use some G/W at the same csa as your line conductors. Nowt wrong with over sizing a cable.

Or, make sure your terminations to enclosure are bomd proof then have a juicy G/W to the earth bar.

Piranaha nuts are the things you need.
 
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 ---

The fact you are still calling your main earthing conductor your main bonding conductor gives me a headache cause you fail to listen.

You are a pain the proverbial because you refuse to listen. I've been reading your other posts tonight, have a feeling we'll be seeing alot of you soon....oh the joy.
 
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!
 
Does the adiabatic equation not calculate the minium CSA of a CPC for use with swa ? if so then how do i work out thes CSA of a sheet steel plate which is what all thes SWA cables are glanded into ???? I understand using that when your using a single SWA feeding a board for instance,it would be used to calculate the CSA of the armouring ,But when using the gland plate and it contains multiple cables i dont think this equation is applicable , i would have thouth it more likley to be a rule of thumb thing ????

That's not the new name for the main earth.
That's the new name for a main equipotential bonding conductor.
There's been no change to the correct terminology for the main earth, it's still called an earthing conductor
 
check your regs book page 167 544.1 amend 1 2011 - just remember it was you which said i described it wrong

Your still wrong as that's describing a main bonding conductor, not a main earthing conductor. Again I stress two different things.
