Question

Quizplus · Accepted Answer

A double insulated drill has a plastic case with the electrical connections and motor insulated within the tool, which eliminates the need for a separate grounding wire. Option A is not correct because a double insulated tool does not require a ground wire. Option C is not correct because using a three-to-two-prong adapter would have no effect on the insulation of the tool. Option D is not correct because a double insulated tool can be powered by either batteries or electricity, and the type of power source does not affect its insulation.
