Question 1

The Electricity at Work Regulations tell us that 'we must ensure the disconnection and separation of electrical equipment from every source of supply and the separation must be secure'. A procedure to comply with this regulation is called:

Accepted Answer

The requirement to disconnect and separate electrical equipment from every source of supply is covered under the Electricity at Work Regulations. A safe isolation procedure is a procedure used to comply with this regulation and ensure that equipment is disconnected and separated from all sources of electrical energy before work begins. Working at height and hazard risk assessment are not directly related to this regulation. A workstation risk assessment may be important for other aspects of health and safety, but it does not directly address the issue of electrical isolation.

Question 2

'To ensure that the accessories and equipment within a building work as they were intended to work' is one definition of the purpose of:

Accepted Answer

The purpose of functional testing is to ensure that all accessories and equipment within a building work as intended. Option A, testing electrical equipment, is more specific and does not encompass all accessories and equipment. Option B, inspecting electrical systems, focuses more on the condition and safety of the systems rather than their functionality. Option D, polarity testing, is a specific type of testing for electrical circuits and does not cover all accessories and equipment.

Question 11

Under the Health and Safety at Work Act an employee is responsible for:

Accepted Answer

Under the Health and Safety at Work Act, employees are responsible for wearing personal protective equipment (PPE) provided to them and taking reasonable care of themselves and others to avoid injury. Employers are typically responsible for maintaining plant and equipment and providing PPE.

Question 12

Accepted Answer

The answer of The maximum inspection and re-test period for...

Question 13

Instrument calibration certificates are usually valid for a period of:

Accepted Answer

Instrument calibration certificates are typically valid for one year, as calibration needs to be checked annually to ensure accuracy and reliability.

Question 14

The Electricity at Work Regulations absolutely forbid the following work activity:

Accepted Answer

The Electricity at Work Regulations prohibit live repair work on electrical circuits, as this can be extremely dangerous and result in electric shocks or even fatalities. It is essential to de-energize electrical circuits before conducting any repairs or maintenance work on them. Working at height, testing live electrical systems and working without appropriate PPE are also hazardous activities, but they may be permitted if adequate safety measures are implemented.

Question 15

Which hand tools would you use for removing cable insulation?

Accepted Answer

Side cutters or a knife are the best hand tools for removing cable insulation as they can easily cut through the insulation without damaging the conductors. A screwdriver, wood chisel, and tenon saw are not suitable for this task.

Question 16

Which hand tools would you use to cut across a floorboard before lifting?

Accepted Answer

The answer of Which hand tools would you use to...

Question 17

Which hand tools would you use to cut and remove a notch in a floor joist?

Accepted Answer

A wood chisel and saw are the best choice for cutting and removing a notch in a floor joist. The chisel can be used to carefully chip away at the wood, while the saw can be used to make initial cuts or cuts that require more precision. Side cutters or a knife may be useful for smaller tasks or finishing work, but aren't ideal for larger cuts. A screwdriver is not appropriate for cutting wood, and a tenon saw is designed for making more complex joints and cuts.

Question 18

A tong test instrument can also correctly be called:

Accepted Answer

A tong test instrument is another name for a clip-on ammeter, which is used to measure the current in a conductor without making direct contact with it.

Question 19

All electrical test probes and leads must comply with the standards set by the:

Accepted Answer

HSE Guidance Note GS 38 specifically addresses the requirements for electrical test probes and leads, ensuring they are designed and used safely to prevent electrical accidents.

Question 20

The test required by the IET Regulations to ascertain that the CPC is correctly connected is called:

Accepted Answer

The test required by the IET Regulations to ascertain that the CPC (circuit protective conductor) is correctly connected is continuity of protective conductors. This test is necessary to ensure that the CPC is providing the required level of protection against electric shock in the event of a fault. The continuity test checks for any breaks or interruptions in the CPC and ensures that it is properly connected to the Earth terminal.
