The City & Guilds 2365-02 Level 2 Diploma in Electrical Installations (Buildings & Structures) is the foundation-level UK electrical qualification for trainee electricians, delivered through approved centres. It is assessed by several online e-volve multiple-choice unit exams - typically 40 questions for Health & Safety (Unit 201), Principles of Electrical Science (Unit 202) and Installation Technology (Unit 203), and 20 for Communication (Unit 210) - plus a practical wiring assessment (Unit 204) and short written tasks. Pass marks vary by unit, for example around 65% for Unit 202. The qualification covers HASAWA and the Electricity at Work Regulations, Ohm's law, power, AC theory and magnetism, cable and containment types, final circuits, TN-S/TN-C-S/TT earthing systems, and basic inspection and testing. It is the natural stepping stone to the Level 3 Diploma (2365-03) and the 18th Edition. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

Sample C&G 2365 Level 2 Practice Questions

Try these sample questions to review concepts for the C&G 2365 Level 2 exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which UK statute is the primary piece of legislation placing a general duty on employers and employees to ensure health and safety at work?
A.The Electricity at Work Regulations 1989
B.The Health and Safety at Work etc. Act 1974
C.The Building Regulations 2010
D.BS 7671:2018+A2:2022
Explanation: The Health and Safety at Work etc. Act 1974 (HASAWA) is the overarching primary legislation in the UK that places general duties on employers, employees and the self-employed. Other regulations such as the Electricity at Work Regulations 1989 are made under its umbrella.
2Under the Electricity at Work Regulations 1989, what is the FIRST action that should normally be taken before working on an electrical circuit?
A.Connect a temporary supply
B.Prove the test instrument, isolate and prove the circuit is dead
C.Inform the client in writing
D.Replace the protective device
Explanation: Safe isolation requires proving the voltage indicator on a known live source, isolating and locking off the supply, then proving the circuit dead, and finally re-proving the tester. This 'prove-test-prove' sequence prevents working on conductors that are still live.
3Which device is used to lock off an isolator so that it cannot be re-energised while work is in progress?
A.A residual current device
B.A padlock and lock-off kit
C.A circuit breaker
D.An RCBO
Explanation: A lock-off kit with a personal padlock physically secures the isolating device in the OFF position. The worker keeps the only key, ensuring no one else can restore the supply while they work on the circuit.
4What is the correct order of priority in the hierarchy of risk control measures?
A.PPE, isolation, substitution, elimination
B.Elimination, substitution, engineering controls, administrative controls, PPE
C.Administrative controls, PPE, elimination, substitution
D.Engineering controls, PPE, elimination, isolation
Explanation: The hierarchy of control prioritises removing the hazard entirely (elimination), then substitution, then engineering controls, then administrative controls, with personal protective equipment (PPE) as the last resort because it only protects the individual wearing it.
5Which UK regulations require certain dangerous occurrences, injuries and diseases to be reported to the enforcing authority?
A.COSHH 2002
B.RIDDOR 2013
C.PUWER 1998
D.The Work at Height Regulations 2005
Explanation: RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013) requires employers and the self-employed to report specified workplace injuries, occupational diseases and dangerous occurrences to the HSE.
6Which set of regulations is concerned with the safe handling of substances hazardous to health, such as solvents and dusts?
A.COSHH 2002
B.RIDDOR 2013
C.The Manual Handling Operations Regulations 1992
D.The Electricity at Work Regulations 1989
Explanation: The Control of Substances Hazardous to Health (COSHH) Regulations 2002 require employers to assess and control exposure to hazardous substances such as dusts, fumes and solvents, using safety data sheets and control measures.
7When selecting a ladder for short-duration access work, which check should be carried out before use?
A.Confirm it is painted to identify ownership
B.Inspect for damage and ensure it is on firm, level ground at the correct angle
C.Ensure it is at least 6 metres long
D.Tie it only at the bottom
Explanation: Under the Work at Height Regulations a ladder must be inspected for defects, placed on firm, level ground and set at the correct angle (approximately 75 degrees, the 1-in-4 rule), and secured to prevent slipping before use.
8A small electrical fire involving live equipment has started. Which type of fire extinguisher is suitable for use on live electrical equipment?
A.Water (red)
B.Foam (cream)
C.Carbon dioxide (black)
D.Wet chemical (yellow)
Explanation: A carbon dioxide (CO2) extinguisher, identified by a black label, is suitable for electrical fires because it is non-conductive and leaves no residue. Water and foam conduct electricity and must not be used on live equipment.
9What is the main purpose of a safety data sheet (SDS) supplied with a hazardous product?
A.To advertise the manufacturer's other products
B.To provide information on hazards, safe handling, storage and first aid
C.To record who purchased the product
D.To list the product's retail price
Explanation: A safety data sheet provides the information needed to use a hazardous substance safely, including its hazards, precautions for handling and storage, PPE requirements, and first-aid and emergency measures. It supports the COSHH risk assessment.
10Which colour combination identifies a mandatory safety sign, such as 'eye protection must be worn'?
A.Red and white
B.Yellow and black
C.Blue and white
D.Green and white
Explanation: Mandatory signs, which instruct that a specific action must be taken, are blue circles with a white symbol. Examples include 'wear ear protection' or 'wear eye protection'.

C&G 2365 Level 2: Suggested Study Strategy

1Focus your hours on Unit 202 (Electrical Science) - it is the largest knowledge unit, so master Ohm's law (V = I x R) and power (P = V x I) until the calculations are automatic
2Learn the safe isolation sequence cold: prove the tester, isolate and lock off, prove dead, then prove the tester again
3Memorise the harmonised cable colours (brown = line, blue = neutral, green-and-yellow = earth) and standard device ratings (6 A lighting, 20 A radial, 32 A ring)
4Be able to tell TN-S, TN-C-S (PME) and TT earthing systems apart by how the earth is provided
5Know the dead-test sequence in order: continuity of protective conductors, continuity of ring conductors, insulation resistance, then polarity
6Complete all 100 practice questions and review every miss with the AI tutor before sitting each unit exam
