This paper was used for my last exam which i did fail, then did another paper and passed, would would love to have correct answers to these please.
I have put the questions and below i have put how many marks the question is worth.
I need your help on this please.
1) A low resistance ohm-meter is belived to be giving incorrect readings. State
A) two methods which could be used to verifiy the accuracy of the instrument
B) the action to be taken if the meter is found to be inaccurate
( 6 Marks)
2) State three activities which require a FULL ELECTRICAL installation certificate?
( 6 Marks)
3) State the:
A) three forums which must be completed following the installation of a new circuit?
B) Person who is responsible for deciding the date of the next test on the forms in a)
C) person to who the forums are given
( 6 Marks)
4) the value of resistance of a earth electrode used on a TT system is be measured using an earth loop impedance test instrument. State:
A) Why isit necessary to isolate installtion before testing
B) What action is to be taken with the earthing conductor before testing and why?
C) why the earth loop reading can be recorded as the electrode value?
( 6 Marks)
5) An electrician is carry out work on a three line and neutral installation, Forming part of a TN-S system. List all points that should be tested between to ensure the installation is totally DEAD.
( 6 Marks)
6) When carrying out a visual inspection prior to commissioning of an installation, identify three possible faults which could be identified at:
A)A pendant type luminaire with 2 plate wiring
B) a consumer unit
( 6 Marks)
7) List the test instruments used and typical measurement range for the following TESTS.
A) Continuity of protective conductors for the ring final circuit.
B) Insulation resistance test at a distribution board
C) Polarity test on lighting circuit
( 6 Marks)
8) Electrical operatives working on site for a number of weeks need special faciilities for tools and equipment: STATE
A) Suitable storage methods for tools and heavy equipment
B) What precautions should be taken with materials on site
( 6 Markks)
9) state three methods of procedures necessary to make an area safe before starting work.
( 6 Marks)
I hope to get answers to these as i have tried but have failed. Also, People doing there 2330 level 3, Get these answers, i am sure this will be useful to you too.
