The insulation resistance of two kinds of hand-held power tools is not less than
Insulation resistance is the most basic insulation index of electrical equipment and electrical circuit. For the handover test of low voltage electrical equipment, the insulation resistance of the motor, the distribution equipment and the distribution line shall not be lower than 0.5M at ambient temperature (for the running equipment and circuit, the insulation resistance shall not be lower than 1M /kV).
The insulation resistance of two types of hand-held power tools is not less than 2M.
Low voltage electrical equipment and its connecting cables and two circuit insulation resistance should not be less than 1M ohms; in a relatively humid environment should not be less than 0.5M; the two circuit of the small bus insulation resistance should not be less than 10M. The insulation resistance of class I hand held electric tools should not be less than 2M.
