Which of the following best describes a journeyman electrician?

A journeyman electrician is defined as an individual who has successfully completed a formal apprenticeship program in the electrical field and has obtained the necessary licensure to work independently. This designation signifies that the electrician possesses both the theoretical knowledge and practical experience required to perform electrical work safely and competently across a variety of settings.

Completion of an apprenticeship not only involves extensive hands-on training under the supervision of experienced professionals but also the study of relevant theories, codes, and standards that govern electrical installations and systems. As a result, a journeyman electrician is qualified to take on projects without direct oversight, embodying the skillset necessary to ensure compliance with building regulations and safety protocols.

The other choices do not accurately capture the essence of a journeyman electrician. For instance, having no formal training, supervising apprentices, or still being in training do not fulfill the criteria needed to attain licensure and independence in the electrical trade. Thus, the best description of a journeyman electrician is someone who has completed an apprenticeship and is licensed to operate alone in their field.
