30、operated snow movers rated 250 V or less to be employed in accordance with the National Electrical Code, ANSI/NFPA 70. 1.2 These requirements do not cover riding-type snow movers or snow movers intended for commercial or industrial use or for use in hazardous locations as dened in the National Elect
31、rical Code, ANSI/NFPA 70. 1.3 In addition to the requirements in this standard, a snow mover shall comply with 4.1, 4.2.2 4.2.3, 4.2.5, 5, 6, 9.1 9.5, 10.1, and 11 of the Snow Throwers Safety Specications, ANSI B71.3. Exception: Markings shall be considered durable and permanent if they comply with
32、Permanency of Marking, Section 44, of this standard.

33、asurement 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 3.2 Unless otherwise indicated, all voltage and current values specied in this standard are root-mean-square. 4 Glossary 4.1 For the purpose of this standard the fol
34、lowing denitions apply. 4.2 APPLIANCE COUPLER A single-outlet, female contact device for attachment to a exible cord as part of a detachable power-supply cord to be connected to an appliance inlet (motor attachment plug). 4.3 APPLIANCE INLET (Motor Attachment Plug) A male contact device mounted on a
35、n end product appliance to provide an integral blade conguration for the connection of an appliance coupler or cord connector. 4.4 APPLIANCE (FLATIRON) PLUG An appliance coupler type of device having a cord guard and a slot conguration specied for use with heating or cooking appliances. 4.5 AUTOMATI
36、CALLY CONTROLLED PRODUCT A product is determined to be automatically controlled if it complies with one or more of the following conditions: a) The repeated starting of the product is independent of any manual control after one complete cycle of operation, after which some form of limit device opens
37、 the circuit.

39、n the product is energized, the initial starting of the motor may be intentionally delayed beyond intended, conventional starting. d) For a product employing a motor with a separate starting winding, during any single predetermined cycle of operation, automatic changing of the mechanical load reduce
40、s the motor speed sufficiently to reestablish starting-winding connections to the supply circuit. 4.6 COMPONENT A device or fabricated part of the appliance covered by the scope of a safety standard dedicated to the purpose. When incorporated in an appliance, equipment otherwise typically eld instal
41、led (e.g. luminaire) is considered to be a component. Unless otherwise specied, materials that compose a device or fabricated part, such as thermoplastic or copper, are not considered components. 4.7 CONTROL, AUTOMATIC ACTION A control in which at least one aspect is non-manual. 4.8 CONTROL, AUXILIA
42、RY A device or assembly of devices that provides a functional utility, is not relied upon as an operational or protective control, and therefore is not relied upon for safety. For example, an efficiency control not relied upon to reduce the risk of re, electric shock, or injury to persons during nor
43、mal or abnormal operation of the end product is considered an auxiliary control. 4.9 CONTROL, MANUAL A device that requires direct human interaction to activate or rest the control. 4.10 CONTROL, OPERATING A device or assembly of devices, the operation of which starts or regulates the end product du
44、ring normal operation. For example, a thermostat, the failure of which a thermal cutout/limiter or another layer of protection would mitigate the risk of re, electric shock, or injury to persons, is considered an operating control. Operating controls are also referred to as regulating controls . 4.1
45、1 CONTROL, PROTECTIVE A device or assembly of devices, the operation of which is intended to reduce the risk of re, electric shock, or injury to persons during normal and reasonably anticipated abnormal operation of the appliance whereby during the evaluation of the protective control/circuit, the p
46、rotective functions are veried under normal and single-fault conditions of the control. For example, a thermal cutout/limiter, or any other control/circuit relied upon for normal and abnormal conditions, is considered a protective control. Protective controls are also referred to as limiting control
47、s and safety controls . 4.12 CONTROL, TYPE 1 ACTION The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain conditions) of its operating value, operating time, or operating sequence has not been declared and tested under this stan
48、dard. 4.13 CONTROL, TYPE 2 ACTION The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain conditions) of its operating value, operating time, or operating sequence have been declared and tested under this standard. 4.14 CORD CONNE
49、CTOR A female contact device wired on exible cord for use as an extension from an outlet to make a detachable electrical connection to an attachment plug or, as an appliance coupler, to an equipment inlet. 4.15 DIRECTLY ACCESSIBLE MOTOR A motor that can be contacted without opening or removing any part, or that is located so as to be accessible to contact. 4.16 ENCLOSURE That portion of the snow mover that: JANUARY 20, 2012 ELECTRIC SNOW MOVERS - UL 1090 7UL C
