GMJ 6035 Electrical Mock *2

Fault diagnosis reveals a serious fault in a domestic installation which could result in serious electric shock if nor rectified. Which one of the following persons should be informed immediately in this situation?

• The health and safety executive

• The local building control Authority

• The owner/occupier of the property

• The institute of engineering technology

Fault diagnosis is being undertaken in a building during non-working hours (when the building is unoccupied). A serious and life-threatening fault is discovered to the wiring of a circuit and rectification of the fault will require major works. Which one of the following actions would be the most appropriate in this situation?

• The circuit should remain un-touched until a suitable meeting with the client is arranged

• The circuit should be securely isolated until the client can be informed of the risk

• The circuit should be stripped out until an agreement to rewire it is made

• The section of the building concerned should be cordoned-off and notices posted

Which one of the following is the most likely consequence if a loose neutral connection within a lighting circuit is not rectified?

• Increased energy bills

• Fire

•   Electric shock

• Burns

Which one of the following is the reason for applying temporary continuity bonds to pipe work?

• They are applied after cutting a section of plastic pipe to minimise the risk of electric shock should the pipe be carrying a residual fault current

• They are applied before cutting a section of plastic pipe to minimise the risk of electric shock should the pipe be carrying a residual fault current

• They are applied after cutting a section of metallic pipe to minimise the risk of electric shock should the pipe be carrying a residual fault current

• They are applied before cutting a section of metallic pipe to minimise the risk of electric shock should the pipe be carrying a residual fault current

Which one of the following tools would be used to cut a copper conductor within a flexible cable to the correct length?

• Hacksaw

• Jigsaw

• Side cutters

• Craft knife

Which one of the following types of connection is a commonly used within a joint box used in domestic wiring systems?

• Screw

• Compression

• Crimp

• Clamp

Which one of the following tests would use a test voltage of 500 V d.c.?

• Continuity of protective conductors

• Continuity of ring final circuits

• Insulation resistance

• Polarity

A test for safe isolation of an electrical system should be carried out using

• An Ammeter

• An insulation resistance tester

• A digital manometer

• An approved voltage indicating device

What is resistance measured in?

• Watts

• Volts

• Amps

• Ohms

Which type of electrical test is carried out to confirm that line and neutral conductors are connected correctly and not crossed?

• Polarity test

• RCD test

• Insulation resistance test

• Earth continuity test
