UL 250:2000 pdf download Household Refrigerators and Freezers
Scope
i.1 This Standard applies to self-contained household refrigerators and freezers designed to be installedand used in residential occupancies in accordance with the Canadian Electrical Code, Part l. CSAStandard C22.2, and the National Electrical Code,ANSI/NFPA 70.
1.2 These requirements apply to household refrigerators and freezers intended for connection to 15 or 20A. 100 to 140 V or 15 A. 200 to 250 V. sinale phase. alternating-current (ac) circuits: and combinationac/dc circuits or direct-current (dc) circuits where the dc voltage does not exceed 30 V.
1.3 The terms “appliance”,”refrigerator,”product,”equipment , and “unit” are used interchangeablyand refer to all household refrigerators, combination refrigerator-freezers,freezers, and refrigeratedkitchen units or any part thereof covered by this Standard unless specifically noted otherwise.
1.4 The equipment is air-cooled emploving hermetic refrigerant motor-compressors or is of the absorptiontype employing electricity as a heat source. These requirements apply to (a) freestanding, wal-hungrecessed, and buil-in refrigerators and freezers: (b) refrigerators and freezers for use in recreationavehicles;(c) refrigerated kitchen units; and (d) accessories.
1.5 A product that contains features, characteristics, components, materials, or systems new or differentfrom those in use when the Standard was developed, and that involves a risk of fire, electric shock, orinjury to persons, shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the level of safety for the user of the product asoriginally anticipated by the intent of this Standard.
2 Definitions
2.1 For the purpose of this Standard, the following definitions apply
2.2 ABSORPTION TYPE REFRIGERATOR – A refrigerator in which electricity is used as a heatsource.
2.3 ACCESSORY – An optional electrical device, such as an ice maker, intended for installation in orconnection to a refrigerator for the purpose of modifying or supplementing the functions of therefrigerator. lt may be factory installed or intended for installation by the user or service personnel
2.4 BARRIER – A partition for the insulation or isolation of electric circuits, for the isolation of electricarcs, or for isolation of moving parts or hot surfaces. ln this respect, a barrier may serve as a portion ofan enclosure or as a functional part.
2.5 BOND STRENGTH – The load applied in tension, compression, flexure, peel, impact, cleavage, orshear, required to break an adhesive assembly with failure occurring in or near the plane of the bond.
2.6 BUILT-IN REFRIGERATOR (OR FREEZER) – A recessed type refrigerator (or freezer) intended forslide-in installation, into a confined space and trimmed to blend with room decor.
2.7 CIRCUIT, EXTRA-LOW VOLTAGE – A circuit that has an ac potential of not more than 42.4 V peak (30 V), and power of 1 00 VA or less; or 30 V dc supplied by a primary battery; or supplied by a Class 2 transformer; or supplied by a combination of a transformer and fixed impedance that, as a unit, complies with all the performance requirements for a Class 2 transformer. A circuit that is derived from a circuit that exceeds 30 V by connecting resistance or impedance, or both, in series with the supply circuit to limit the voltage and current, is not considered to be an extra-low voltage circuit.
