Do double insulated equipment require a third wire?

Explanation:
Double insulated equipment uses reinforced insulation to keep all live parts isolated from the user, so there are no exposed metal parts that could become live. Because of that safety design, a protective earth (third) wire isn’t required. If you see a device with a ground connection, it isn’t Class II double-insulated.
