Inspection & Testing mock test 1

Why should all documentation given after initial verification be kept in a safe place?

• Adds value if selling the property

• To reduce insurance premiums

• As reference for any persons inspecting any work at a later date

• To comply with any local authority inspections

For safety reasons, what is the recognised status for undertaking and signing off inspection and test work?

• a skilled person

• an instructed person

• a person qualified in PAT testing

• a person who is a member of the IET

On which two documents is prospective fault current recorded?

• Minor Electrical Installation Works Certificate and Schedule of Inspections

• Electrical Installation Certificate and Schedule of test results

• Electrical Installation Certificate and Minor Electrical Installation Works Certificate

• Schedule of Inspections and Schedule of test results

Which is one of the documents that must accompany an Electrical Installation Certificate?

• Minor Electrical Installation Works Certificate

• Landlords safety certificate

• Electrical indemnity certificate

• Schedule of Inspections

On completion of electrical work, all appropriate documentation should be

• Given to the building inspector

• Retained by the electrician

• Left next to the mains position

• Given to the person ordering the work

Functional testing may involve

• Insulation resistance testing

• Disconnecting an appliance

• Turning on a light switch

• Continuity testing

A check for phase sequence at the main intake to a three phase installation indicated a result of L1, L3, L2. The correct orientation at each subsequence distribution board is

• L1, L3, L2

• L2, L3, L1

• L2, L1, L3

• L3, L2, L1

One reason for testing that the phase sequence is the same across an installation is

• The hold-on relay in motor starters can be connected to the correct phase

• Fluorescent lamps will not make moving machinery appear stationary

• The installer will know the direction of rotation of three phase machines

• Power factor correction capacitors can be connected the right way around

The table shows the results for a test carried out on a 30mA RCD to BSEN 61008, that is being used for additional protection. Which statement best describes the result of the test?

• The RCD fails as it should trip within 0.4s at 15mA leakage

• The RCD fails as it should trip within 300ms at 30mA leakage

• The RCD passes as it trips quicker than all the required tripping times

• The RCD fails as it should trip within 0.02s at 150mA leakage

What is the minimum permitted value to be found on a protective device at the origin of 230V single phase circuit where Ze is 0.12Ω?

• 1500

• 6000

• 3000

• 10000

Answer explanation

The minimum permitted value on a protective device is calculated using the formula: Minimum Permitted Value = 230V / 0.12Ω = 1916.67V. Rounding up, the correct choice is 3000V.
