A tool made of non-conductive material and insulated from electrical energy is called what?

The term that accurately describes a tool made of non-conductive material and insulated from electrical energy is "double insulated tool." Double insulation is a design standard that provides protection against electric shock by incorporating two levels of electrical insulation, effectively allowing the tool to be used safely without a separate ground connection.

In double insulated tools, the outer casing is made of non-conductive material, providing the first layer of insulation, while the internal electrical components are also insulated. This design minimizes the risk of electrical shock, even if there is a failure in the primary insulation.

Understanding this standard is important for workplace safety, as it allows electricians to utilize certain power tools without needing to worry about them being grounded. Tools designed with this level of insulation are particularly useful in environments where grounding may be impractical or poses additional hazards.

The other types of tools mentioned, such as grounded tools or electrically safe tools, have different safety characteristics and may involve specific grounding practices or different insulation standards.
