Earth's in a ring

[Benj2012]

When terminating the two earth Conductors for a ring would you put it in the same terminal or two separate ones

what does the magic yellow book say?

How do you do it in a radial?

I'm asking for an answer not a question.

Harsh!

firstly...... Is it for high leakage currents ie IT equipment OR low leakage currents?

and YES it DOES make a difference

just saying

I'm asking  questions that will guide you to your answer.

Thanks.

Didn't mean it in a rude way just got exam tomorrow and needed an answer, sorry  :Salute

so you expect to be spoon fed all the answers to pass your test but have no idea where to find the answers yourself?

in some cases it can make a difference, and the answer is in 7671

@Benj2012 a ring circuit is considered a single circuit. The two brown (line) cables are connected together, the two blue (neutral) cables are connected together. It therefore follows that the two earths are connected together.

 

[Benj2012]

Just got confused cause it says in on site guide separate terminals 

I have looked but my teacher has told us the cpc goes in the same terminal but 7671 says different terminals

but not in the same terminal on high integrity

Think about it this way....

What difference would it make if they were under two, separate but linked,  terminations as opposed to 1?

and.... are there any regulations that might state that they should be under separate terminations?

 

[Benj2012]

Just says in on site guide only reason that I could think it matters is putting out of place the earthing arrangement of the mcbs 

 

[NozSpark]

Like others have said.... have a look at High Integrity earthing in your regs book

 

[Andy™]

ill even help you... 543.7.1.4
