Which of the following is NOT a major requirement for manufacturing live line tools?

Manufacturing live line tools involves ensuring that the tools can withstand the demands of high-voltage environments while maintaining safety and usability. Among the requirements for these tools, adequate insulation is critical to prevent electrical shock, while strength is necessary to endure the physical stresses encountered during use.

The emphasis on lightweight design is also vital because tools that are too heavy can lead to fatigue for the user, potentially compromising safety and efficiency. Therefore, a lightweight design enhances usability without sacrificing durability.

Heavyweight design, on the other hand, does not align with the requirements since heavier tools could be cumbersome, leading to higher risks for the worker. Therefore, some manufactured tools need to be designed with lightweight materials to ensure easy handling and operation. This makes heavyweight design an unsuitable approach in the context of manufacturing live line tools.
