Question regarding neutral for Ring final Circuit.

[nazoom]

I am carrying out the continuity for a ring final test for a single phase TN-S system. When doing the end to end Neutral I don't get a reading!! What is wrong here and what Code does apply (Code 1-3)?

Many Thanks.

Sure its a ring?

a) L-L ok?
b)E-E ok?
Loose or disconnected N if they are..

Get checking...

 

[nazoom]

There is no disconnected neutral I checked.

However a) L-L is ok,
E-E is ok
but N-N no reading!!

What's wrong here? And what code is used for the Periodic inspection reporting?

What do you think?

Get an electrician to have a look, basic stuff he'll soon sus it.

Code 2, but you should really know that if you are carrying out a periodic / EICR?

If you get no reading then there IS a break in the ring somewhere. It's obvious....that's what the test is checking for.....if you don't believe your test results then why bother testing? The break in continuity doesn't have to be at an accessory....could be any number of things. Bit worrying if you are doing EICRs......

It is for my exam. I did it today and there is tomorrow. but I cant understand if there is no reading for N-N does that mean that the ring is discontinues and therefore code 2 is used? Or is it incorrect polarity?

 

[Barry Rathbone]

exam eh..

info only then..:13:

Old cert's?
Any idea of number of sockets ?

Resistance readings of L and CPC rings?(or is that asking to much)
It callled experience sometimes too, check everywhere, twice....ask the owner/householder questions as to where to look for more sockets.

Then wait for the buzz when you finally find it!:54:25 years and I do "Die Hard" when I find the fault the last 4 sparks couldn't find!!

It means the neutral part of the ring is not continuous......think about how a ring is constructed and why,and you will work it out for yourself.

I'm keeping quiet sorry, exams are for a purpose.Swot up.Took me 2 min to find in regs.

All i need to know is does No reading for N-N means that the ring is discontinues?

 

[Barry Rathbone]

Of course it does. Its discontinued. Has no continuity.

Gave in!

I already told you that in post 10.....cant you read?

Reading some of the OP's threads over the last couple of days, Iam sure he said that the test rig has deliberate faults added for the candidates to code for.
