What is one benefit of using double insulation in electrical devices?

Using double insulation in electrical devices provides a significant benefit in terms of safety, specifically through reducing the risk of electric shock. Devices with double insulation are designed with two independent layers of insulating material, which provide two barriers between the electrical components and the user. This design is particularly important in preventing electrical shock, as it minimizes the chances of current reaching the user even if the outer layer is damaged.

In general, double insulation is especially common in handheld tools and appliances used in environments where grounding cannot be easily implemented. The effectiveness of this approach is reflected in safety standards and regulations that promote the use of double insulation as a means to protect both users and equipment from electrical hazards. Hence, through this additional layer of protection, users can operate devices with a much lower likelihood of encountering harmful electrical issues.
