MULTIPLE CHOICE QUESTION

1 min • 1 pt

What is the first step in carrying out safe working practices for electrical isolation?

Selecting the correct test instruments

Identifying suitable points of isolation

Conducting a risk assessment

Applying warning notices

Answer explanation

The first step in safe working practices for electrical isolation is conducting a risk assessment. This ensures that all potential hazards are identified and addressed before proceeding with isolation.

Which of the following is crucial for the correct identification of circuit(s) to be isolated?

Using a multimeter

Referring to circuit diagrams

Applying locking devices

Conducting a visual inspection

Answer explanation

Referring to circuit diagrams is crucial for correctly identifying which circuits to isolate, as they provide detailed information about the circuit layout and connections, ensuring accurate isolation.

What should be considered when identifying suitable points of isolation?

The proximity to the main power supply

The ease of access for maintenance personnel

The ability to lock and secure the isolation point

The colour of the isolation switch

Answer explanation

The ability to lock and secure the isolation point is crucial for safety, preventing unauthorized access and ensuring that maintenance can be performed safely. Other factors, while important, do not prioritize safety as directly.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Which instrument is typically used to prove that a circuit is de-energised?

A voltmeter

A clamp meter

A proving unit

A continuity tester

Answer explanation

A proving unit is specifically designed to verify that a circuit is de-energised by simulating the presence of voltage. Other instruments like voltmeters and clamp meters measure voltage or current but do not confirm de-energisation.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

What is the correct method for testing a circuit to ensure it is safe to work on?

Test the circuit with a live wire

Use a non-contact voltage tester

Test the tester on a known live source, test the circuit, then re-test the tester

Use a thermal imaging camera

Answer explanation

The correct method is to test the tester on a known live source, then test the circuit, and re-test the tester. This ensures the tester is functioning properly and confirms the circuit's safety before working on it.

6.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

Which type of locking device is most appropriate for securing an isolated circuit?

A padlock with a unique key

A combination lock

A cable tie

A magnetic lock

Answer explanation

A padlock with a unique key is the most secure option for isolating a circuit, as it provides controlled access and prevents unauthorized use. Other options like combination locks or cable ties lack the same level of security.

7.

MULTIPLE CHOICE QUESTION

1 min • 1 pt

What is the purpose of applying warning notices during isolation procedures?

To inform others that the circuit is under maintenance

To indicate the location of the main power supply

To provide instructions for re-energising the circuit

To display the name of the technician

Answer explanation

Applying warning notices during isolation procedures serves to inform others that the circuit is under maintenance, ensuring safety and preventing accidental re-energization.
