23、s cover cord reels for general use, as well as cord reels herein referred to as special-use cord reels intended to be mounted on or in electrical utilization equipment such as appliances, portable lamps, or similar equipment. These cord reels are intended for use in accordance with the National Elec
24、trical Code, NFPA 70. 1.2 These requirements also cover reels for use in factories, household workshops, garages, commercial facilities and construction sites where an additional degree of protection against the risk of the entrance of water, dust or other contaminates might be needed. 1.3 These req
25、uirements also cover cord reels for use above but not in hazardous locations in commercial garages as dened in the National Electrical Code, NFPA 70. 1.4 A cord reel, as covered by these requirements, is a reel equipped with, or intended for use with, a length of exible cord. The reel provides a mea
26、ns for the cord to be unwound by the user as desired. The reel is provided with a take-up mechanism, by which the cord is rewound on the reel. The mechanism by which the cord is extended or retracted to the desired length might or might not be driven by a motor. A latch is provided in some cases to
27、restrain the action of a spring take-up mechanism while the cord reel is in use. 1.5 A cord reel shall be permitted to employ Ground-Fault Circuit-Interrupter(s) (GFCI) outlet(s) at the load connection. The Ground-Fault Circuit Interrupters shall be investigated under the applicable requirements in
28、the Standard for Ground-Fault Circuit Interrupters, UL 943. Added 1.5 effective February 26, 2010 2 Glossary 2.1 For the purpose of this standard, the following denitions apply. 2.2 BRUSH The part, which is mounted on the xed part of the cord reel or the rotating hub, that conveys the current to the
29、 slip ring. 2.3 COMMERCIAL/INDUSTRIAL USE CORD REEL A cord reel subject to severe use in factories, commercial garages, construction sites, and similar locations requiring a harder service type cord. 2.4 CORD STORAGE DEVICE A spool for storage of insulated exible cord but does not enclose or support
30、 uninsulated live parts. 2.5 CORD REEL A device used to store insulated exible cord with allowance for variable lengths of cord to be extracted from the reel or spool. 2.6 GENERAL-USE INDOOR CORD REEL A cord reel for use only in indoor, dry, residential type applications. 2.7 GENERAL-USE OUTDOOR COR
31、D REEL A cord reel that is acceptable for use outdoors as well as indoors in residential applications. The cord reel is intended to be stored indoors when not in use.

32、ION FROM UL 2.7.1 OPEN NEUTRAL PROTECTION Consists of the opening of the line contacts of a protective device when either live contact loses power, whereby the output potential is interrupted to provide shock hazard protection. As an example, if the input neutral opens due to a broken conductor or l
33、oose plug connection, the protective device circuitry would not receive power, and therefore would not operate to provide protection. A current path from line to ground could exist, under these circumstances; a person in contact with the live conductor could receive a lethal shock. (A faulty applian
34、ce that has an internal insulation failure could allow the case to become energized.) Added 2.7.1 effective February 26, 2010 2.8 RETRACTION, AUTOMATIC Retraction by inherent force, such as by spring tension, to position the cord back onto the spool of the cord reel. 2.9 RETRACTION, MANUAL Retractio
35、n by the user, such as by hand cranking action, to position the cord back onto the spool of the cord reel. 2.10 SLIP RING The part, which is mounted on the xed part of the cord reel or the rotating hub, that is the circular conductor on which the brush rides.

37、ord is wrapped on when the cord is stored on the cord reel. 2.12 SPECIAL-USE CORD REEL A cord reel for use only permanently on or in electrical utilization equipment such as appliances, portable lamps, or similar equipment. 3 General 3.1 Components 3.1.1 Except as indicated in 3.1.2, a component of
38、a product covered by this Standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components generally used in the products covered by this standard. 3.1.2 A component is not required to comply with a specic requirement that: a) Involves a feat
39、ure or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 3.1.3 A component shall be used in accordance with its rating established for the intended conditions of use. 3.1.4 Specic components
40、 are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 3.2 Units of measurement 3.2.1 Valu
41、es stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 3.3 Undated references 3.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that
42、 code or standard. JUNE 25, 2004 CORD REELS - UL 355 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL CONSTRUCTION ALL CORD REELS 4 General 4.1 A cord reel shall be formed and assembled so that the cord reel has the strength and rigidity nec
43、essary to resist the abuses to which the cord reel is subjected in service, without increasing the risk of re, electric shock, or injury to persons due to total or partial collapse with resulting reduction of spacings, loosening or displacement of parts, or other serious defects. 4.2 The constructio
44、n and the mechanical functioning of a cord reel shall be such that the cord will not be subjected to abrasion, kinking, pinching, jamming, or other treatment that might damage the cord conductors or insulation. 4.3 A cord reel that employs Ground-Fault Circuit Interrupter outlet(s) and is connected
45、to the power supply by a means of exible cord with an attachment plug shall be provided with open neutral protection, with the GFCI. Added 4.3 effective February 26, 2010 4.4 A cord reel construction that employs slip rings or an equivalent mechanism and also employs Ground-Fault Circuit Interrupter
46、 outlet(s) shall be provided with open neutral protection, with the GFCI. Added 4.4 effective February 26, 2010 5 Enclosure 5.1 Wiring terminals that will be inside an outlet box or the equivalent when the reel is installed need not be additionally enclosed. 5.2 The enclosure of a cord reel provided
47、 with a motor shall prevent molten metal, burning insulation, aming particles, or similar objects from falling on ammable materials, including the surface upon which the product is supported. 5.3 The requirement in 5.2 will necessitate the use of a barrier of nonammable material under a motor unless
48、: a) The structural parts of the motor or of the product provide the equivalent of such a barrier; b) The protection provided with the motor is such that no burning insulation or molten material falls to the surface that supports the product when the motor is energized under each of the following fa
