In regards to flexible cords, what is defined as "hard-usage"?

Cords that are easily damaged
Cords used for light duty applications
Cords designed for heavy-duty work conditions
Cords only permitted indoors

The correct answer is: Cords designed for heavy-duty work conditions

The term "hard-usage" in the context of flexible cords refers to cords that are specifically designed for heavy-duty work conditions. These cords are constructed to withstand harsher environments and demanding applications, such as in industrial settings or for outdoor use where they may be subjected to abrasion, mechanical stress, or exposure to chemicals. Such durable construction typically involves materials that are resilient to wear and tear, ensuring that they can support high power loads while maintaining safety and reliability. In contrast, options that describe cords as easily damaged or used for light duty applications do not meet the criteria for "hard-usage," as they lack the necessary durability and strength. Additionally, the mention of cords being permitted only indoors does not align with the concept of hard-usage, since these cords are often utilized in various environments, including outdoor conditions where toughness and resistance to external factors are crucial. Therefore, the definition of "hard-usage" specifically pertains to cords that are engineered to perform well under challenging conditions, making heavy-duty work applications their primary focus.
