A qualified person is defined as someone who has demonstrated skills and knowledge related to the construction and operation of electrical equipment and installations and has safety training to identify the hazards and reduce the associated risk. Which two terms complete the phrase describing the required scope?

• A. Operation and maintenance
• B. Construction and operation
• C. Installation and testing
• D. Troubleshooting and repair

Answer: (B)

The required scope for a qualified person includes both the building and the use of electrical equipment and installations, along with safety training to identify hazards and reduce risk. That means the two terms that complete the phrase are construction and operation. Construction covers the activities involved in creating, wiring, and installing equipment and systems, while operation covers how those systems are used and controlled safely during normal and abnormal conditions. Together, they reflect competence in both setting up and operating electrical installations with an emphasis on safety. The other options miss part of this combined scope: they either emphasize only maintenance, only installation and verification, or only troubleshooting and repair, none of which fully capture both construction and ongoing operation.
