1.1 This Standard applies to self-contained household refrigerators and freezers designed to be installed and used in residential occupancies in accordance with the Canadian Electrical Code, Part I, CSA Standard C22.2, and the National Electrical Code, ANSI/NFPA 70.

These requirements apply to household refrigerators and freezers intended for connection to 15 or 20 A, 100 to 140 V or 15 A, 200 to 250 V, single phase, alternating-current (ac) circuits; and combination ac/dc circuits or direct-current (dc) circuits where the dc voltage does not exceed 30 V.

The terms “appliance”, “refrigerator”, “product”, “equipment”, and “unit” are used interchangeably and refer to all household refrigerators, combination refrigerator-freezers, freezers, and refrigerated kitchen units or any part thereof covered by this Standard unless specifically noted otherwise.

The equipment is air-cooled employing hermetic refrigerant motor-compressors or is of the absorption type employing electricity as a heat source. These requirements apply to (a) freestanding, wall-hung, recessed, and built-in refrigerators and freezers; (b) refrigerators and freezers for use in recreational vehicles; (c) refrigerated kitchen units; and (d) accessories.

A product that contains features, characteristics, components, materials, or systems new or different from those in use when the Standard was developed, and that involves a risk of fire, electric shock, or injury to persons, shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally anticipated by the intent of this Standard.
