Of course I don't have a copy of the questions because that is wrong and totally contrary to the rules of the City and Guilds examination boards.
I do happen to have a.... err.... very good memory and given a bit of time might be able to reproduce, sorry, recall some of the questions !
1. A new 3 phase circuit supplying an electric kiln has been installed in an existing installation. State the THREE documents that MUST be completed and issued to the client on completion of the work. (3 Marks)
2. State THREE documents on which the value of prospective fault current must be recorded. (3 Marks)
3. State THREE items of information that an inspector must have, which may be recorded on charts and diagrams, before carrying out an initial inspection. (3 Marks)
4. State THREE different examples off a limitation that may be agreed with a client which is NOT already stated on the Periodic Inspection Report. (3 Marks)
5. State from the test results shown, the most likely instrument to have been used
a) 0.03 Ohms (1 mark)
b) 125 M Ohms (1 mark)
c) 125 ms (1 mark)
6. State three situations where the human sense of touch could be used by an inspector (3 marks)
7. list the first three tests to be carried out on a newly installed radial circuit (3 marks)
8. State the effect on conductor resistance when
a) temperature is decreased
b) length is increased
c) csa is increased (1 mark each)
9. list the three different protective conductors that may be installed in most electrical installations (3 marks)
10. State:-
a) the relevant document to be referred to when considering the use of test leads to carry out an insulation resistance test (1 mark)
b) two characteristics of these test leads or probes (2 marks)
And I believe, that's the first half of Part A. 30 marks down, 30 to go and 90 on Part B.
I reckon everyone is feeling pretty confident right now, thinking " This 2391 'aint all that !!" .........
but stand by........ it gets worse ....... to be continued.
Just got out of the 2391 written tonight ..... and it all started so well !! That rule of thumb calculation (tabulated x 0.8) cost me 5 marks. Really annoying because that's about one thing I actually knew, just didn't include it.
