Tools made of nonconductive material and insulated from electrical energy are called?

• A. Double-Insulated/Ungrounded tools
• B. Grounded tools
• C. Insulated tools
• D. Ungrounded tools

Answer: (A)

The situation tests electrical protection through layered insulation and the absence of a grounding path. Double-insulated tools are built with two independent layers of insulation between live parts and the user, so a fault won’t create a conductive path to the hands. Because there’s no grounding connection, these tools are ungrounded, which is exactly what keeps the user safe when the tool is in contact with energized parts. While grounded or simply insulated tools might offer some protection, they rely on different designs, and the description “nonconductive material and insulated from electrical energy” aligns most closely with double-insulated/ungrounded tools.
