  • SCOPE

    1 Scope

    1.1 These requirements 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 Electrical 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 requirements also cover cord reels for use above but not in hazardous locations in commercial garages 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, a length of flexible cord. The reel provides a means 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 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 the Standard for Ground-Fault Circuit Interrupters, UL 943.
