August 2391-10 taken today

Just sat it myself last night I also put voltage indicator yes! And rt was 2.11ohms which requires circuits to be tested separately well that's what I put!

Why would you want to test the circuit separately??

 

[tony mc]

I think he has entered the wrong value and forgot that its Mohms not ohms!!!

 

[malcolmsanford]

Lol Tony if it was ohms then it would need checking, I never noticed it was just ohms written.

No I took it as 2.11Mohms and wondered why he would put that each circuit needed investigation.

 

[tony mc]

Exam pressure getting mixed up with what GN 3 actually states.

So 2.11 Mohms would comply!

Yes the twitching sphincter Syndrome, gets you every time

 

[parker56]

im sure the Q 1/200+1/18+1/2.5+1/180+1/145=1/RT
I also got 2.11MOHMS
it also ask for any commets to be recorded in observations & recommendations.
so I put futher investergation of low readings of cicuits reading 18 & 2.5Mohms code 3, but circuits do comply

Right, exam over analysed to death now not sure if I have passed, I must stop now:
Other answers:

Three conditions before MEWIC to be issued:
Do not impair safety of existing; designed constructed and tested to BS7671, complies with BS7671
(signature line on MEWIC)(only got one of these)

Prepare for IR testing:
Loads removed, sensitive devices disconnected or linked out, no shorts between conductors
(last one not precise enough, perhaps; should be L or N to E)

Insulation resistance other question resistance: as length, CSA, temperature rise:
IR Down ohm Up
IR None ohm Down
IR None ohm up

Insulation resistance calculation was just nasty getting so close to the limit
Observations: circuit with 2.5Mohm near the limit requiring investigation, may indicate circuit deterioration.

Section B
Certificates required for new installation and periodic test:
EIC with SofTR and SofI and PIR with SofTR and SofI

TNS diagram description was OK I think may have forgotten to say it was the secondary winding of the supply transformer.

RCBO test
Idn 30mA 300ms on positive and negative cycles, 5Idn 150mA 40ms on positive and negative cycles, 0.5Idn 15mA no trip on positive and negative cycles
(added +ve and –ve at the last minute)
Do Ze to ensure presence of effective earth
(I think)

Tests of lighting circuit:
Continuity, Insulation resistance, polarity, Ze,
Low resistance ohmmeter, insulation resistance tester(ohmmeter in chapter 4), low resistance ohmmeter, Earth fault loop impedance tester
(messed up the number of marks and tried to add stuff to make it up to 8 marks for each not 8 marks overall probably only got 4)
Reasons for order:
Ensure all CPC/ earth in place, ensure no short circuits/leakage, ensure no wrong connections
(really not sure about that one, can’t remember what I answered)
No instrument: Functional test at end

Sorry for the rambling on.
Hope everyone did well.
Roll on 10th October, please!

Hi richard on the testing of the lighting circuit hope you ment Zs and not Ze.lol as all the other existing circuits that were not under test would be live with no earth. Opppps

 

[pirhead]

I thought it was a very easy paper with comparison to others. Learned a good tip for remembering things to look for during periodic inspection SADCOW=SAFETY, AGE, DETERIORATION, CORROSION, OVERLOAD, WEAR AND TEAR. It might be useful in the future

 

[russty]

Anybody at all had there results yet from this exam?
Using the results calculator gives a date of monday just gone they should of annouced it, but havent heard anything myself yet?

Results receipt calculator

 

[parker56]

I thought it was oct 10

 

[Richard Burns]

Yeah I had Oct 10th as well, still 10 days to wait, arrrgh!
The C&G calculator gives this (42 days from exam date)

 

[johng36]

Doin my head in not knowing!!

 

[russty]

Sorry my mistake, must of read the wrong date.

Tick, Tock!!

 

[johng36]

June results was 51% passed

 

[johng36]

Just had a call from training centre results in !!!! PASSED !!! whooooohooo !!

 

[parker56]

well done to you :hurray:

 

[Richard Burns]

Well done johnGill36 a significant accomlishmennt, lucky you to get the results now!
My training centre will call when they are in, soon please!

 

[Richard Burns]

Ha Ha ha Haa YES: you have achieved the Pass standard in 2391-10!
What was i worrying about; it was dead easy, no stress, no strain, no sweat exerted.

Thank goodness for that!
and relax.
Just got to wait for the certificate now.

 

[parker56]

well done to you (what stress)
