What is the main advantage of using a double-insulated tool?

• A. It is lighter
• B. It protects from electrical hazards
• C. It is easier to use
• D. It has fewer parts

Answer: (B)

The main advantage of using a double-insulated tool is its ability to protect the user from electrical hazards. Double insulation refers to a safety feature that includes two layers of insulation between the electrical components and the tool's exterior, which minimizes the risk of electric shock. This design is crucial because it eliminates the need for a ground connection, providing added safety in environments where grounding may not be reliable or feasible. By using materials that are less conductive and incorporating a secondary layer of insulation, these tools ensure that if the first layer were to fail, the second layer serves as a backup to prevent any electrical leakage that could harm the user. This feature makes double-insulated tools particularly important in construction and carpentry settings, where moisture and other factors could elevate the risk of electrical shock.
