What type of service flexible cords No. 12 or larger can be repaired if spliced correctly?

Flexible cords that are rated No. 12 or larger and referred to as "hard service" cords can indeed be repaired if spliced correctly. Hard service flexible cords are designed to withstand heavier mechanical stress and environmental conditions compared to lighter duty cords. They are commonly used in industrial settings and where a durable electrical connection is necessary.

The ability to repair hard service cords hinges on the fact that these cords are constructed to handle more demanding applications, which includes potential splicing. The process of splicing must involve proper techniques, ensuring that the electrical and mechanical integrity of the cord is maintained and that its protective features are adequately restored.

In contrast, lighter service cords would not typically support the same level of mechanical stress or environmental factors, making repairs less viable in a safe and reliable manner. Thus, recognizing the properties and intended use of hard service cords is crucial in understanding why they are the correct option in this scenario.
