UL 82-2009 pdf download – Electric Gardening Appliances.
1 Scope 1 .1 These requirements cover cord-connected, electrically-operated gardening appliances, such as cultivators, edger-trimmers, and the like, rated 250 volts or less for use in accordance with the National Electrical Code, NFPA 70. 1 .2 These requirements also cover battery-operated gardening appliances. 1 .3 These requirements do not cover sprayers, foggers, or equipment for use in hazardous locations as defined in the National Electrical Code, NFPA 70. 1 .4 These requirements do not cover electrically operated lawn mowers or garden tractors or their attachments. 1 .5 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard. 2 Glossary 2.1 For the purpose of this standard the following definitions apply. 2.2 ACCESSIBLE PART – A part so located that it can be contacted by a person, either directly or by means of a probe or tool, or that is not recessed the required distance behind an opening. See Accessibility of Moving Parts, Section 8. 2.3 BASIC INSULATION – The insulation applied to live parts to provide basic protection against electric shock. 2.4 CUTTER AREA – The area through which the cutting means moves and in which a foreign object may be struck by the cutting means. 2.5 DEAD-MAN CONTROL – A control intended to automatically interrupt power when the actuating force supplied by the operator is removed.
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.
