Pass mark for 2391 Oct 2011

[cjp1]

Morning Everyone,
Did the 2391 last night and dont think I did enough to pass, been revising for months but as soon as the exam starts the mind went blank.
Completely balls up the question about the swa feeding the garage, worried about running out of time so went off on one about check this and that as if it was a new install then right at the end realised it was an existing cable so expecting no marks for that.
Does anyone know how many marks you need to pass?
I can remember the questions so when I get time I will type them out on here.
Cheers Chris

 

[CRAGS]

Don't think there is a pass mark set in stone depends how candidates do in the exam. Usually though bout 90 marks or roughly 60% as a rough guide.

 

[cjp1]

on that note I think I will book a retest now.

 

[onfire25]

The next exam is december and registration closes at the end of october but i felt the same as you......felt confident about the exam.......felt confident about my answers and then read a few remarks on here and have started to doubt myself. I have enquired if i can just book in for the december exam at the same centre and was told no.......the earlyist i can re-take if need be is February 2012!

Good luck though........am sure you have done allright........we all cant remember everything spot on!

 

[Daniel Clark]

i took it last night as well, and ill be honest unless im really stupid i found the first 4 questions really hard and the majority of the 1st section, im thinking it could of been down to the course i took because we mainly concentrated on past papers so when questions arose i hadnt really seen before i really struggled

 

[Richard Burns]

Don't lose heart yet, you may have done enough, I missed out one 10 mark question on my exam (not thinking clearly and jumped to the next!) and was panicking for the next 42 working days but passed in the end.

I agree with Crags variable pass mark around 60% ish, but never specified by C&G.

I just spoke to city & guilds this morning and explianed my concearn with last nights exam and they said that I can book onto the December 2011 exam now incase I failed the one last night.

I started a new thread in the testing section with this post, but it seemed invisible to anyone except me!

Didn't seem too bad?
It lacked the usual earthing system diagram and the insulation resistance calculation.

Couple of questions that I've remembered:


Section A:

If a MCB has a Ics of 10kA and a Icn of 6kA and an overload of 8kA occurs, what action should you take?

State three human senses that could be used during an inspection of an installation.

What documents should you be provided with when carrying out a PIR?

a) What is the maximum impedance for a 300mA RCD protected TT system?
b) What is the maximum allowable earth electrode resistance?
c) how would you test a TT system with a 300mA RCD

What are the required test voltages for the following circuits:
a) 12v SELV
b) 650V
c) 400v Kiln circuit

List the correct names of the conductors that connect these items to the main earthing terminal:
a) earth electrode
b) incoming gas pipe
c) forgotten

List three precautions to be taken prior to commencing an insulation test.

State the IP code of:
a) Something in Zone 2 of a bathroom
b) A barrier? in a DB that can be accessed with out the use of tools
c) forgotton!


State the earthing arrangement at the supply that has that has:
a) supply with the only earth located at the supply transformer
b) a multicore supply cable with a seperate earth and neutral
c) PEN

If a ring continuity circuit has resistances of L-L 0.4ohm, N-N 0.4ohm, CPC 0.? What will the resistance be if measured at a socket? (possibly asking R1+ R2, can't remember!)

State 3 functional tests that should be carried out after testing a socket(???) circuit?
What happens to the resistance of a conductor if its 0.4ohm to start with:
It halves in in length?
It doubles in diameter?
It doubles in length and halves in diameter?


Section B:

Scenario involving a house that needed to be PIR'd, had a garage connected with SWA and had a loft extension that had had a new lighting circuit, socket circuit and shower? Also new CCU fitted.

List 5 checks you would make on the SWA as part of the PIR.
Explain how you would do these checks.

State two Statutory DOCUMENTS relevant to inspection and testing.

State three non-statutory PUBLICATIONS relevant to inspection and testing.

List all the documents to be completed for the scenario mentioned.

Explain how to perform a CPC continuity test on a lighting circuit.

Explain the dangers of using faulty testing equipment?

List the tests in order that you would carry out on a newly installed ring final circuit.

a) Explain why the measures Zs values cannot be directly compared to the maximum tabulated values in BS7671
b) calculate from the table given whether the stated Zs values would comply with BS7671 after calculating the correction factor (it wasn't worded like this!)

Explain IN DETAIL the testing current and the maximum trip time of a 30mA RCD.
State the dangers of a RCD test. Or requirements?



That's all I can remember!

 

[Guest112]

they grade it on how everybody does like the gcse its not a set passmark, get ready for a looooong wait for your results

I thought I had failed my 2nd attempt at the 2391 theory so I booked onto the next exam date which I was told you could not do but was then told you could. While making my way to take the 3rd attempt at the exam got a phone call from the training centre..........I quickly turned the car round raced home and cracked a few cans of beer open....Quite excellent timing on the part of the training centre.

Don't give up hope you never know

I started a new thread in the testing section with this post, but it seemed invisible to anyone except me!

Sorry Mate, did not mean to upset anyone by starting this thread, how did you answer the question about the swa supplying the external garage?
I think that is the question I ballsed up, I answered it as if it was a new installation completly missed the pir bit as I was worried about running out of time.
Cheers Chris

 

[Mark.W]

I forgot to mention to use a low resistance ohmmeter for the swa R1+R2 test, schoolboy error I know..... Does anyone know if I lose all the marks for the question??

 

[Sparky Ninja]

I've got a copy of the paper in the car, I'll fetch it in (in the morning) and post up any questions you guys want to discuss.

Responded to your PM :willy_nilly:

Widdler you are a legend thank you!

I wasn't joking, the thread didnt work for anyone apart from me! After 18 hours it had no replys and 1 view (me) no idea what happened?!

For the SWA question, I put;
Check the thermoplastic covering for cracks / damage.
Check for conductor correctly connected into terminals.
Check Steel Armour is earthed.
Check Banjo is fitted.
Check rating of cable to see if its suitable.

No idea if its right though!

 

[Guest112]

good luck to you guys who sat the exam it can be a hard one especially the way city and guild ask their questions but a well deserved qualification after passing the exam most greatly received cert I ever had good luck guys!!!

 

[jbroady]

Hi all also did the 2391 on thursday, my mind must of gone blank coz i thing I didn't do well. I think out of all the questions i ballsed up the most was the swa question & it was 15 marks just on that, crap!!!!

 

[Sparky Ninja]

Apologies for the delay guys, major networking issues at work lost me my whole weekend!!

I've attached some scans of the paper.

 

[Mark.W]

What are 3 practical steps an inspector can use, to ensure safety? Q5
3 possible outcomes for not checking the leads? Q6

 

[aaelectric]

have you got the answers for this??

 

[Mark.W]

No! You?

 

[Banjo]

What are 3 practical steps an inspector can use, to ensure safety? Q5

1. Safely Isolate and lock off
2. Use warning signs
3. Use barriers

Thats what i would of put for the answers.

 

[Sparky Ninja]

have you got the answers for this??

I don't "have" the answers, but I do "know" the answers.

C&G won't release a crib sheet till the exams have been redistributed.

 

[Mark.W]

State the conditions that need to be taken into account when comparing measured and maximum tabulated values of zs??

 

[Banjo]

State the conditions that need to be taken into account when comparing measured and maximum tabulated values of zs??

I would say

1. Conductor operating temperature
2. Ambient temperature

 

[Mark.W]

I would say

1. Conductor operating temperature
2. Ambient temperature

See that's what I thought at first, but then I thought they would be taken into account when calculating zs, not comparing measured to max tabulated?!

 

[sparky74]

my brain went to mush, it's far to late to be sitting this exam, 6.30pm i ask myself

 

[Mark.W]

Does anyone know what the pass mark is? I heard it's 60%. is that 60% overall or 60% for part A and 60% for part B??

 

[cjp1]

my brain went to mush, it's far to late to be sitting this exam, 6.30pm i ask myself

my brain went to mush aswell mate revised all day and doing past papers etc then starting the exam at that time is b*ll*cks would have much sooner took the exam in the morning.

 

[twodds]

i did the exam at the same time lads,sat there thinking god i wonder what all the other sparks are thinking ,i got a sore head ,finger and eyes trying to think.Its the hardest thing ive ever tried remembering the( whole gn3 in 2.5 hrs ) all i can say is good luck lads if you past well done its not easy and i revised for 3 to 4 months solid and still think crap did i give the right answer
good luck chaps

 

[breakerman]

Widdler, would u be kinda enough to PM me a copy of that oct 2391 paper as well, I got the exan Dec 01 gotta pass it, much appricated

Hi i took the exam the same night at Lowestoft and the question on SWA completely ballsed me up i should have taken more time reading the intro part of the 6 questions. Overall i don't think i have quite made enough to pass but i will definately be there for another go, now i know what the paper is like.

LIST: I took the wrong path on this and done the first 3 steps of the ring final circuit, only to find that the next question was what tests would need GS38 leads? Then i new i had done some thing wrong with my diagrams..

All the best of luck mate and all who took the exam on the 20 Oct..

Cheers Ian.

 

[ian65]

Hi all, i am awaiting my results for the 20th Oct. and am doughting my score i am hoping to hear about the 1st of December if not a pass will rebook and take it asap.

Good luck to all... Ian.

 

[emb111]

Hi Guys anyone had their results yet from 20th october 2011 C7G 2391 ????

 

[Richard Burns]

I think the results for 20th October 2391-10 should be out about 19th December (42 days from exam date) so still some time to wait yet!

 

[cjp1]

Its a joke you have to wait that long really, I am sure they could get them marked and sent back a bit quicker if they wanted.

 

[SPARTYKUS]

Like wading through treacle

 

[Rampage]

My tutor had a meeting with the guy that writes the exams and marks the papers the other week. And there's only the one person marking all of them!

 

[cjp1]

I think the results for 20th October 2391-10 should be out about 19th December (42 days from exam date) so still some time to wait yet!

Hi Richard, Do you know if the results get sent to the training center/college where you took the exam or do they get sent to you at home?
Cheers Chris.

 

[alanl]

The results come out at the earliest, the beginning the 5th December, as it is anywhere between 40 and 48 days for them to be marked.
I'm not sure where your Instructor got the idea that there is only one person marking the whole lot, I was told there are 3 or 4 doing it, and once one batch have been marked by one person, they are then sent to another to check.
Any anomalies, like unclear questions that have 2 valid answers are then corrected. And they are then sent back to the 'Chief', and a pass level established - there is never one set pass mark, though it is thought that 100 marks will give you a pass, whether it was a hard or easy exam. Opinion after the Oct. 11 exam was it was a little more difficult than usual, with some questions that have not been seen before.
Alan.

 

[Richard Burns]

Hi Richard, Do you know if the results get sent to the training center/college where you took the exam or do they get sent to you at home?
Cheers Chris.

The results are sent to your exam centre and then the exam centre forwards certificates on to you; normally near the date the centre may have received the results and you may be able to telephone, and if they are nice they will tell you if you have passed:hurray:

 

[ian.settle1]

Its a joke you have to wait that long really, I am sure they could get them marked and sent back a bit quicker if they wanted.

Depends upon what other work the person marking has to do besides marking the papers

 

[sparky74]

We'll i phoned the college today where i took the 2391 theory on the 20th oct 2011 and was told i passed.......Yipee, nearly fell off me chair when she said i'd passed. I didn't think i did too bad in the exam but talked myself out of passing it in the 8 long weeks of waiting that followed, lol. Anyway obviously the results are available so best you people get on the phone, could be some good news just before christmas, right im off for a beer or 10, good luck...

 

[Richard Burns]

Well done mate, that is the response you want to hear:hurray:. Hope the beers went well definitely a reason for celebration.

 

[Rampage]

Got my results yesterday as well. Passed.
Just waiting for the D&V results now!

 

[Richard Burns]

Yeeaahh! well done, onward and upward, good work, not an easy one to pass without effort

 

[cjp1]

morning all,
Well done to everyone who passed the oct 2391, I passed too:hurray:
Cheers Chris

 

[Richard Burns]

morning all,

Cheers Chris

Well Done! Time for a deserved celebration. such a weight off your mind.
Who says loads of people fail, good crowd here.

 

[sparky74]

Well done to everyone who passed, as Richard say's it is hard one, especially at 6.30pm lol.

 

[parker56]

well done to all that passed.
