Question 1 of 10
1. Question
The continuity of the line, the neutral, and the protective conductors of the final circuit ring was checked at the distribution board of the installation. The ohm values of r1, r2 & rn were recorded on the test results schedule used to calculate R1 & Rn and R1 & R2; however, one particular outlet socket was used to perform Steps 2 and 3 of the continuity of the final circuit ring test procedure.
Correct
If the cps and line conductors had been implemented at the socket outlet, R1 & R2 would have been confirmed regardless of the conversion; however, with the neutral and circuit protection conductors being implemented, the inspector would effectively test between R1 & R2 and not R1 & Rn.
Incorrect
If the cps and line conductors had been implemented at the socket outlet, R1 & R2 would have been confirmed regardless of the conversion; however, with the neutral and circuit protection conductors being implemented, the inspector would effectively test between R1 & R2 and not R1 & Rn.

Question 2 of 10
2. Question
When performing a sequence of tests, what test would the inspector consider necessary for the complete electrical installation to be safely isolated?
Correct
Although the external Earth Loop Impedance is a live test, the disconnection of the main Earth conductor is necessary to eliminate parallel Earth paths.
Incorrect

Question 3 of 10
3. Question
What other tests, other than the answer given in Q7, would the inspector consider necessary for the complete installation to be safely isolated?
Correct
If the bonding driver is disconnected, as required by Test Method 2, any Defect current induced by external metalwork would leave the individual, who may be in contact with metalwork, unprotected.
Incorrect
If the bonding driver is disconnected, as required by Test Method 2, any Defect current induced by external metalwork would leave the individual, who may be in contact with metalwork, unprotected.

Question 7 of 10
7. Question
How does the inspector confirm that the installation complies with the design and requirements for the construction of BS 7671?
Correct
The inspector confirmed that the installation complies with the design and requirements for the construction of BS 7671 Through the inspected and tested during construction and on completion of the installation
Incorrect
The inspector confirmed that the installation complies with the design and requirements for the construction of BS 7671 Through the inspected and tested during construction and on completion of the installation

Question 8 of 10
8. Question
Provide the reason(s) why the inspector should inspect and test the facility during its construction period.
Correct
Each issue has a practical element; what an inspector would do. Typically conducted as part of the inspection and testing process; however, the candidate (inspector) must know the reason(s) why the inspection and testing procedure is performed during the construction of the facility.

Question 9 of 10
9. Question
An inspector has a range of duties when carrying out an initial verification, most critical of all, is:
Correct
When inspecting an installation, the inspector has four tasks, but the primary one is safety; that is, there is no danger to people or livestock. Testing the designed cable size or whether it is retained over the cable length is not the responsibility of the inspector. These duties are those of the respective designer and installer.

10. Question
Information relating to the supply of the facility should be readily accessible to the inspector; if the information is not available, which of the following information can not be obtained by calculation, measurement, or inspection?
Correct
Moreover, the inspector needs to know and understand the specifications of the Electrical Installation Certificate (EIC), since this certification can be used by the Court of Law and the inspector has due diligence to ensure that the document is done correctly (see Defence Regulation 29 of the 1989 Electricity at Work Regulations).
