What is the minimum rating of fiberglass live line tools?

The correct choice reflects the established standard for fiberglass live line tools, which is rated for a minimum of 100,000 volts per foot. This rating is crucial because these tools are designed for use on high-voltage systems, providing electrical workers with the necessary safety margin when working near live electrical lines. The 100,000 volts per foot rating ensures that the tools can safely withstand electrical stress without breaking down or allowing current to pass through, which is essential for protecting the worker from electrical hazards.

Understanding this standard is important for anyone involved in electrical maintenance and safety practices, as using tools that meet or exceed this minimum rating significantly reduces the risk of electrical accidents when working with high voltages.
