Which hard skills should a lineman possess?

The correct choice highlights essential hard skills that a lineman must possess to perform their job effectively. Electrical knowledge is crucial because linemen work with high-voltage power lines and must understand electrical theory, safety procedures, and the operation of various electrical systems. Climbing skills are also vital, as linemen often need to scale poles and towers to install and maintain equipment, requiring a combination of physical fitness and safety techniques. Lastly, equipment operation is key since linemen use a wide range of specialized tools and machinery, such as bucket trucks, transformers, and various hand tools.

The other options discuss skills that, while important in their respective fields, do not align with the core responsibilities of a lineman. Sales and marketing skills focus on promoting and selling products, which is not relevant to the technical and safety-focused work that linemen do. Communication and customer service skills, while beneficial for teamwork and interactions with the public, are considered soft skills and are not the specialized hard skills needed for performing lineman duties. Lastly, design and computer programming skills pertain more to technical fields like software engineering or electrical design and are not specifically necessary for a lineman's role, which centers around physical labor and electrical work in the field.
