2.9 GROUND-SUPPORTED APPLIANCE – An appliance that, during normal operation, is supported entirely or in part by the ground. 2.1 0 GUARD – A part of an assembly provided for shielding parts that may present a risk of fire, electric shock, or injury to persons. 2.1 1 HAND-SUPPORTED APPLIANCE – An appliance that, during normal operation, must be completely supported by the user. 2.1 2 LEAKAGE CURRENT – All current or currents, including capacitively-coupled currents, that may be conveyed between exposed conductive surfaces of an appliance and ground or other exposed conductive surfaces of the appliance. 2.1 3 LIVE PART – A part energized with respect to earth or energized with respect to some other part. 2.1 4 OPERATOR CONTROL – Any device necessary for operating an appliance including a drive- engaging control, a movable-guide control, a drive-speed changing control, and a deflector control. 2.1 5 REINFORCED INSULATION – An improved basic insulation with such mechanical and electrical qualities that it, in itself, provides the same degree of protection against electric shock as double insulation. It may consist of one or more layers of insulating material. 2.1 6 SUPPLEMENTARY INSULATION – An independent insulation provided in addition to the basic insulation to protect against electric shock in case of mechanical rupture or electrical breakdown of the basic insulation. An enclosure of insulating material may form a part or the whole of the supplementary insulation.3 Components 3.1 Except as indicated in 3.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered by this standard. 3.2 A component is not required to comply with a specific requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 3.3 A component shall be used in accordance with its rating established for the intended conditions of use. 3.4 Specific components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specified limits, and shall be used only under those specific conditions. 4 Units of Measurements 4.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. CONSTRUCTION 5 Frames and Enclosures 5.1 General 5.1 .1 The frame and enclosure of an appliance shall have the strength and rigidity necessary to resist the abuses to which it is likely to be subjected during normal service without total or partial collapse resulting in a risk of fire, electric shock, or injury to persons due to reduction of spacings, loosening or displacement of parts, and other serious defects.
7 Handles 7.1 An appliance shall have a handle or handles that permit grasping the appliance with both hands. Exception: An appliance that is manipulated with one hand, such as grass shears, may have only one handle. 7.2 Other than as noted in 7.4, the handles or surfaces most likely to be grasped by the user during the normal operation of an appliance shall be made of or covered with an insulating material that complies with the requirements in 7.5, the Handle Tests, Section 34, and the dielectric voltage withstand test in accordance with 79.1 and entry 2 of Table 79.1 . 7.3 With reference to 7.2, examples of surfaces that are likely to be grasped by the user during normal operation include a lever, handle, or button for a switch or other operator control. Surfaces of a guard for a switch or other operator control are also included if located where likely to be grasped. 7.4 The outer surfaces of a handle or other area likely to be grasped during normal operation shall not be of electrically conductive material, unless: a) Insulation complying with the requirements in 79.1 and entry 2 of Table 79.1 is interposed between the surfaces likely to be grasped and: 1 ) The cutting member; and 2) Any metallic guard for the cutting member; and b) Surfaces likely to be grasped: 1 ) Are double-insulated from live parts; or 2) Do not enclose electrical components and are separated from all dead metal parts that enclose electrical components by insulation complying with the requirements in 79.1 and entry 2 of Table 79.1 .UL 82-2008 pdf download.
