Q1. Which piece of UK legislation places the core legal duty on employers to ensure electrical equipment is maintained to prevent danger?
  • A.  The Electricity at Work Regulations 1989
  • B.  The Portable Appliance Testing Act 1990
  • C.  The Consumer Protection Act 1987
  • D.  The Electricity Safety, Quality and Continuity Regulations 2002
Show answer & explanation
✓ Answer: A. The Electricity at Work Regulations 1989
The Electricity at Work Regulations 1989 (EAWR), specifically Regulation 4(2), require that electrical systems be maintained so as to prevent danger. There is no 'Portable Appliance Testing Act' - PAT is simply an industry term for one method of demonstrating compliance. The 2002 Regulations govern electricity distribution networks, not workplace appliances.
Q2. Which statement best describes the protection principle of Class III equipment?
  • A.  Protection relies on limiting the supply voltage rather than insulation or earthing alone
  • B.  Protection relies on a double-pole switch disconnecting both conductors
  • C.  Protection relies entirely on the earth fault loop impedance
  • D.  Protection relies on residual current detection at the socket
Show answer & explanation
✓ Answer: A. Protection relies on limiting the supply voltage rather than insulation or earthing alone
Because Class III equipment is fed from a SELV source, the voltage itself is kept low enough that even direct contact with live parts is unlikely to cause a dangerous shock, removing the reliance on insulation class or earthing as the primary safeguard.
Q3. For a Class II (double-insulated) desk lamp used in a low-risk office, what does HSE-aligned guidance typically suggest regarding formal testing frequency compared to a Class I appliance in the same environment?
  • A.  Class II items generally need less frequent, or in some cases no, earth continuity related testing, though visual checks still apply
  • B.  Class II items always require monthly testing regardless of environment
  • C.  Class II items require the exact same frequency as Class I items with no distinction
  • D.  Class II items are exempt from all future inspection requirements
Show answer & explanation
✓ Answer: A. Class II items generally need less frequent, or in some cases no, earth continuity related testing, though visual checks still apply
Because Class II equipment relies on double insulation rather than an earth path, certain earth continuity tests are not applicable, and testing needs are generally lighter, though visual inspection remains important. This does not mean Class II items are exempt from all future checks.
