Electric tools are divided into two types: handheld and movable. According to the purpose and classification of electric tools: metal cutting, grinding, assembly, road construction, mining, etc
Classification
Class I tools
Tools not only rely on basic insulation in terms of protection against electric shock, but also include an additional safety precaution. The method is to connect accessible conductive parts with the protective (grounding) wire in the installed fixed circuit, in order to prevent accessible conductive parts from becoming charged in the event of basic insulation damage accidents.
Class II tools have a rated voltage exceeding 50V. Tools not only rely on basic insulation for protection against electric shock, but also provide additional safety precautions for double insulation or reinforced insulation, as well as measures that do not protect grounding or rely on installation conditions. There are two types of tool casings for this type of tool: metallic and non-metallic, but the handheld part is non-metallic with a "return" symbol at the non-metallic partClass III tools
