Career Awareness, Industry Practice and Sustainable Technologies flashcards for City & Guilds Electrical Installation (Level 3)

21 of 51 cards from the Career Awareness, Industry Practice and Sustainable Technologies deck — real questions with worked answers.

1. What are the four main sectors of the electrotechnical/construction industry?

   1) Domestic (dwellings), 2) Commercial (offices, shops, retail), 3) Industrial (factories, plants, heavy machinery), and 4) Agricultural. Each has distinct environmental conditions, loadings and regulatory considerations.

2. Distinguish between a 'main contractor' and a 'subcontractor' on a construction project.

   The main (principal) contractor holds the overall contract with the client and manages the whole build. A subcontractor is engaged by the main contractor to carry out a specialist part of the work (e.g. an electrical installation firm).

3. What is the role of a clerk of works on a construction project?

   An independent inspector, employed on behalf of the client/architect, who monitors workmanship and materials on site to ensure they comply with the specification, drawings and standards.

4. Within the construction team, what does an 'M&E' consultant or contractor deal with?

   Mechanical and Electrical services — the building services such as electrical power, lighting, heating, ventilation, air conditioning and plumbing, as opposed to the building structure itself.

5. What is the difference between a quantity surveyor and a building services (electrical) engineer?

   A quantity surveyor manages costs, quantities, valuations and contracts. A building services/electrical engineer designs the electrical and mechanical systems and specifies how they are installed and tested.

6. List the typical hierarchy of operatives on an electrical installation job, from most to least experienced.

   Qualified Supervisor / Approved Electrician → Electrician (qualified) → Apprentice / Trainee → Labourer/Electrician's mate. Supervision and responsibility decrease down the chain.

7. What is the role of the 'principal designer' under CDM 2015?

   The principal designer plans, manages and coordinates health and safety during the pre-construction (design) phase, ensuring risks are designed out where possible and information is passed to others.

8. Name the UK competent person scheme bodies an electrical contractor may register with.

   NICEIC, NAPIT, ELECSA, STROMA and similar Part P / competent person schemes. Registration allows self-certification of notifiable domestic work under Building Regulations.

9. Which document is the UK national standard for electrical installations, and who publishes it?

   BS 7671 (the IET Wiring Regulations), published jointly by the IET (Institution of Engineering and Technology) and BSI (British Standards Institution).

10. What is the JIB and what does it regulate?

    The Joint Industry Board for the Electrical Contracting Industry. It sets grading (e.g. Electrician, Approved Electrician, Technician), pay rates, conditions of employment and the ECS card scheme.

11. What does the ECS card scheme verify?

    The Electrotechnical Certification Scheme card proves an individual's identity, qualifications, grade and health & safety knowledge (via the ECS H&S assessment) for site access.

12. What is the legal status of BS 7671 in the UK?

    BS 7671 is non-statutory (not law in itself), but it is the recognised means of meeting the legal requirements of the Electricity at Work Regulations 1989 and is cited under Part P of the Building Regulations.

13. Define 'competence' as required by the Electricity at Work Regulations 1989.

    A person is competent when they possess sufficient technical knowledge, skill and experience, with an understanding of the hazards involved, to prevent danger or injury when working on or near electrical systems.

14. What are the key features of effective verbal communication on site?

    Clear, concise language; correct technical terminology; active listening; confirming understanding (feedback); appropriate tone; and avoiding jargon when speaking to non-technical clients.

15. Give two advantages of written communication over verbal communication on a project.

    It provides a permanent, traceable record (proof and reference), and it reduces ambiguity by allowing precise instructions, drawings and figures to be conveyed and re-checked.

16. What is a 'permit to work' and why is it used?

    A formal written document authorising specific work under defined safe conditions (e.g. isolation). It controls high-risk tasks, records who is responsible, and ensures coordination so danger is prevented.

17. What is a 'snagging list' in construction?

    A list of minor defects or incomplete items identified (usually near handover) that the contractor must put right before the work is accepted as fully complete.

18. What is the difference between a block diagram and a circuit (schematic) diagram?

    A block diagram shows the main functional units as blocks and their interconnections in simple form. A circuit/schematic diagram shows every component and conductor with standard symbols and the exact electrical connections.

19. What does a 'wiring diagram' show compared with a 'layout drawing'?

    A wiring diagram shows the actual connections and terminations between components (how to wire it). A layout (location) drawing shows the physical position of equipment on a scaled plan of the building.

20. On a layout drawing, what does the scale '1:50' mean?

    1 unit on the drawing represents 50 of the same units in reality — e.g. 1 cm on paper equals 50 cm on site, so $\text{actual length} = \text{drawn length} \times 50$.

21. If a cable run measures 80 mm on a drawing at scale 1:100, what is the real length?

    $80 \text{ mm} \times 100 = 8000 \text{ mm} = 8 \text{ m}$.
