July 2012 2391

[Jackyc]

No practical loads and loads of past papers from early 90s to march 2012. And tutor obviously has a lot of experience as knew all questions threw at him. Only problem if we have failed next re sit available is Decemer which I feel Is a long way away as they are fully booked for next one.

 

[tutorsteve]

Hopefully no resit required then : )

Earth electrode resistance of a generator. How is it measured?

 

[Nath88]

Is it not with a Earth electrode resistance tester and max reading of 20ohms?

 

[Jackyc]

A was what tester.
B was how many additional electrodes are needed
C was how many tests are there.
I put electrode resistance tester. 2 and 3 don't no if I was wright as didnt revise a lot on that area.

 

[Jurasic Spark]

I did mine in Dudley not far from brum.

I here these guys based in Wolverhampton have a very good pass rate:

Courses - Introduction :: Courses :: Mercia Management

 

[Nath88]

I put
A - earth electrode resistance tester
B - 2 additional electrodes
C - 3 tests

Im hoping thats correct, But im sure il be corrected shortly if not

 

[Jackyc]

Same here I am feeling confident after discussing a few answers on here

 

[Bales]

I put
A - earth electrode resistance tester
B - 2 additional electrodes
C - 3 tests

Im hoping thats correct, But im sure il be corrected shortly if not

I hope so too as that is exactly what I put.

I think there was was another question on what tester to use on a TT with a RCD which I put a Earth loop impedance tester.

 

[Nath88]

Yeh i put the earth loop for that one cz i think it says perform a 'live' test? Just wanna get the bloody results now so i can go on and book the design (If i pass)

 

[Jackyc]

Same here mate may do 2396 if I pass

 

[Nath88]

Yeh, may aswell get it done whilst all the calcs are fresh in our minds cz if not itll be like starting afresh again! ha

How many tests would you carry on 30 mA RCBO. Please stat testing currents, and maximum disconnection times.

1. I x 1/2 - 0 deg - 15mA - No trip
2. I x 1/2 - 180 deg - 15mA - No trip
3. I x 1 - 0 deg - 30mA - 300mS
4. I x 1 - 180 deg - 30mA - 300mS
5. I x 5 - 0 deg - 150 mA - 40mS
6. I x 5 - 180 deg - 150 mA - 40mS
7. Functional Test - no current - trip.

What two additional checks would you carry on this device (I think got this wrong ). But after rethinking of question I got to the conclusion that correct answer was:

1. Rating of built in over current protective device
2. Check max Ics.

Question 20. What is the name of the inspection and test for this process? I put initial verification. This was worth 2 marks
Question 21. What documents are supplied upon completion of this inspection and test? This was worth 3 marks

So... Why are they giving out 2 marks for q20 when it is surely only 1 mark? The answer to q21 (electrical installation cert, schedule inspections & schedule test results) suggests that it is correct for 3 marks. Q20 however suggests there may be a periodic inspection involved. What is that additional mark for??? (if it does involve a PIR) why is q21 not worth 6?

Ooops not reading what was wrote correctly

 

[Jackyc]

Got results earlier today and passed so chuffed how did everyone get on?

 

[Jezzas82]

I rang on Monday but they didn't have results. I'll try again. Well done. I hope I'm as happy.

 

[Blackout]

Well found out today I passed the July paper as well as the June. Feels like a waste but atleat I know it wasn't a fluke. Lol.

 

[pinball25]

Got my results today , Passed so happy

 

[Richard Burns]

Well done to those passing the 2391,all well deserved.
Keep your fingers crossed for those still waiting, can't be long now!! and Good luck.
