Who shall be permitted to work on electrical conductors or circuit parts that have not been put into an electrically safe work condition?

• A. Unqualified persons
• B. Journeyman electricians only
• C. Supervisors and technicians
• D. Qualified persons

Answer: (D)

Working on electrical conductors or circuit parts that have not been placed into an electrically safe work condition carries significant shock and arc-flash risk. Only a person who has been trained and demonstrated the ability to identify hazards and implement protective measures—someone qualified—may perform this work. A qualified person understands how to test for voltage, select and use the proper PPE and insulated tools, apply lockout/tagout, and determine whether de-energizing is feasible while keeping the work area safe. Unqualified individuals lack the necessary training to manage these hazards and should not perform such tasks. While a journeyman electrician is typically considered qualified, the rule is about qualification status, not just job title, so supervisors or technicians must also be qualified for the specific task if they are to work on such conductors or circuit parts.
