23、ERMISSION FROM ULINTRODUCTION1 Scope1.1 These requirements cover cord reels for general use, as well as cord reels herein referred to asspecial-use cord reels intended to be mounted on or in electrical utilization equipment such asappliances, portable lamps, or similar equipment. These cord reels ar

24、e intended for use in accordancewith the National Electrical Code, NFPA 70.1.2 These requirements also cover reels for use in factories, household workshops, garages, commercialfacilities and construction sites where an additional degree of protection against the risk of the entranceof water, dust o

25、r other contaminates might be needed.1.3 These requirements also cover cord reels for use above but not in hazardous locations in commercialgarages as defined 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

26、, alength of flexible cord. The reel provides a means for the cord to be unwound by the user as desired. Thereel is provided with a take-up mechanism, by which the cord is rewound on the reel. The mechanism bywhich the cord is extended or retracted to the desired length might or might not be driven

27、by a motor. Alatch is provided in some cases to restrain the action of a spring take-up mechanism while the cord reelis in use.1.5 A cord reel shall be permitted to employ Ground-Fault Circuit-Interrupter(s) (GFCI) outlet(s) at theload connection. The Ground-Fault Circuit Interrupters shall be inves

28、tigated under the applicablerequirements in the Standard for Ground-Fault Circuit Interrupters, UL 943.Added 1.5 effective February 26, 20102 Glossary2.1 For the purpose of this standard, the following definitions apply.2.2 BRUSH The part, which is mounted on the fixed part of the cord reel or the r

29、otating hub, thatconveys the current to the 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 fle

30、xible cord but does not enclose orsupport uninsulated live parts.2.5 CORD REEL A device used to store insulated flexible cord with allowance for variable lengths ofcord 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 typeap

31、plications.2.7 GENERAL-USE OUTDOOR CORD REEL A cord reel that is acceptable for use outdoors as wellas indoors in residential applications. The cord reel is intended to be stored indoors when not in use.AUGUST 26, 2008 CORD REELS - UL 355 4AUL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUC

32、TION ORDISTRIBUTION WITHOUT PERMISSION FROM UL2.7.1 OPEN NEUTRAL PROTECTION Consists of the opening of the line contacts of a protectivedevice when either live contact loses power, whereby the output potential is interrupted to provide shockhazard protection. As an example, if the input neutral open

33、s due to a broken conductor or loose plugconnection, the protective device circuitry would not receive power, and therefore would not operate toprovide protection. A current path from line to ground could exist, under these circumstances; a personin contact with the live conductor could receive a le

34、thal shock. (A faulty appliance that has an internalinsulation failure could allow the case to become energized.)Added 2.7.1 effective February 26, 20102.8 RETRACTION, AUTOMATIC Retraction by inherent force, such as by spring tension, to positionthe cord back onto the spool of the cord reel.2.9 RETR

35、ACTION, MANUAL Retraction by the user, such as by hand cranking action, to positionthe cord back onto the spool of the cord reel.2.10 SLIP RING The part, which is mounted on the fixed part of the cord reel or the rotating hub,that is the circular conductor on which the brush rides.AUGUST 26, 2008COR
