21、le reels and above 50 V and not exceeding 440 V for all other cable reels, and a rated current not exceeding 16 A. They are intended for household, commercial and light industrial and similar purposes, either indoors or outdoors, with particular reference to safety in normal use. This standard does
22、not apply to: cable reeling devices incorporated in appliances or luminaires; cable reeling devices associated with appliances or luminaires. NOTE 1 Requirements for cable reeling devices incorporated in appliances are specified in IEC 60335-1 and IEC 60335-2-2. NOTE 2 Requirements for cable reeling
23、 devices incorporated in luminaires are specified in IEC 60598-1 and IEC 60598-2-25. NOTE 3 A cable reeling device associated with an appliance or luminaire is a device designed to supply a specific appliance or luminaire. It must be fixed to or delivered with the appliance or luminaire, without bei
24、ng incorporated in it and having its own enclosure which provides protection against electric shock. An example is a cable reeling device associated with handlamps according to IEC 60598-2-8. This standard may be used as a guide for cable reeling devices incorporated or associated in appliances or l
25、uminaires as far as it is applicable. 61242 Amend.1 IEC:2008 3 Cable reels complying with this standard are suitable for use at ambient temperatures not normally exceeding 25 C, but occasionally reaching 35 C.
