Electrical Safety, Regulations and Codes of Practice
Core concepts
Understand the regulatory framework: statutory duties, the role of standards and codes of practice, and the principle of working to the current edition. Know the concepts of competence, risk assessment, safe isolation, permits and lock-off, and the requirement to maintain installations in a safe condition. Be familiar with periodic inspection intervals, certification and reporting, and the duty to record departures from standards.
Traps in questions
Questions often test whether a candidate knows that regulations set outcomes, while standards give methods, or that a departure must be justified and recorded. Watch for scenarios where a worker is not competent for the task, or where safe isolation is skipped because the circuit is "known dead". Another trap is assuming a new installation needs no verification.
Worked example / rule of thumb
If a design cannot meet a particular requirement, document the departure, justify the alternative, and record it on the certificate. Rule of thumb: if it is not written down and justified, it did not happen. Always confirm competence and apply safe isolation before any work.
