Earthing inside a submain panel from main swa incomer

What you getting so angry about

 

[Guest 004]

I ask a question, and all you want to is belittle with your inadequate knowledge.

 

[Guest 004]

Makes me understand even more so, that this forum was set up by a non sparks, and with house bashes trying to mod it. Pathetic

 

[Guest 004]

I'm out, ban me if you want, going back to the proper forums.

Why you getting so upset? You've had useful reply's to your OP you just seem to be ignoring them or taking them out of context. Simply you have to size it using the adiabatic equation or use the table in the BYB. Are you incapable of performing a simple calculation or something as you seem to be trying to avoid it?

I'm not angry at all, I have tried to explain things as best I can.
I don't think I have tried to belittle you at all have I?
You came here and asked a question, which has been answered a few times over, we have variously tried to explain why the answers we have given are what they are, yet you just seem to be taking offence at the fact they aren't what you appear to want the answer to be.

What 'proper forum' are you referring to?

Really?? Obviously the Adiabetic returned a value a 0, that is why a NON supplymentary was not installed. Why are you so insistent on this? The equation is not hard hard to follow anyway?

Could you possibly help those of us with inadequate knowledge out by helping us understand what you meant by a supplementary? It's not a term which appears in the regs other than supplementary bonding?

The adiabatic equation used in bs7671 cannot return a value of 0 for any real-world figures.
The reason for people being insistent on it is that it is the method of sizing a cpc which gives the most economical size.

What do you mean by that's the reason a 'NON supplementary' was not installed as you put it? If you mean by running in a separate earthing conductor along side of the cable then obviously the designer has obtained the necessary information from the manufacturer and found the armour to be adequate....How ever your question wasn't that was it? Your question was about taking a fly lead from the banjo to the earthing terminal in the enclosure.

In the time it has taken this thread to develop you could have found an offcut of the SWA to use to make the link to the earth bar couldn't you?

Mr Enigma, far be it for me to defend Dave, or any of the other lads on this forum but I think that it is you who is getting angry. And I believe it's because the answer you have received is not the one you wanted.
Your question was answered very early in the thread and you choose to disagree with the opinions given (your right)

You obviously want to use the enclosure as the earth, and you can, you just need to be sure that it is the correct size equivalent to copper and is mechanically strong enough. As pointed out better to install fly lead and be sure, and of course the way to ascertain the size would be by using the appropriate table, which would give a size of 95mm or use the adiabatic equation.

Also, I agree that the continuity test of .01 ohms is irrelevant, you would get the same result with a bit of 5a fuse wire.

Closing thread, OP has laid his own path here and is now banned... he was given plenty of advice and help but to aim an attack at the mods has sealed his fate ... maybe he needs to educate himself with regards to the work he undertakes rather than attack those giving constructive advice....

PS - Dummy and Pram come to mind!
