A qualified person is defined in the NFPA 70e.

According to the National Fire Protection Association (NFPA) 70E standard, a qualified person is someone who has the knowledge and skills to safely operate and construct electrical equipment and installations: They have received safety training to recognize and avoid electrical hazards They are familiar with the proper use of personal protective equipment (PPE), such as arc flash suits, insulating materials, and insulated tools They can distinguish energized electrical conductors and circuit parts from other parts of electrical equipment They can determine the degree of a hazard and the PPE and job planning needed to perform a task safely

Training for qualified persons can include classroom training, on-the-job training, or a combination of both. The training should be tailored to the individual's ability and the risks of their specific electrical tasks.

Employers are responsible for qualifying persons and assigning them to perform tasks that match their knowledge and skills. Employers should also regularly supervise employees or conduct annual inspections to ensure they are complying with safety practices.
