MULTIPLE CHOICE QUESTION

30 sec • 1 pt

Which of the following is NOT an example of 'exposed-conductive-parts'?

Steel trunking

Metal accessories

Rubber insulation

Steel enclosures of wiring systems

Answer explanation

Rubber insulation is not an exposed-conductive-part; it is used to cover and protect conductive parts. In contrast, steel trunking, metal accessories, and steel enclosures are all conductive and exposed.

What does BS 7671:2018 define as 'extraneous-conductive-parts'?

A conductive part that is part of the electrical installation.

A conductive part liable to introduce a potential, generally earth potential, and not forming part of the electrical installation.

A non-conductive part that introduces a potential.

A conductive part that is always at earth potential.

Answer explanation

BS 7671:2018 defines 'extraneous-conductive-parts' as conductive parts that can introduce a potential, typically earth potential, and are not part of the electrical installation, making the second choice correct.

Which of the following is a key component in preventing electrical shock?

Equipotential bonding

Increasing voltage

Reducing current

Disconnecting the earth electrode

Answer explanation

Equipotential bonding is crucial in preventing electrical shock as it ensures that all conductive parts are at the same electrical potential, reducing the risk of current flowing through a person. The other options do not effectively prevent shock.
