UL 355:2016 pdf free download – STANDARD FOR SAFETY Cord Reels.
6.7 During the examination of a product to determine compliance with 6.1 or 6.2, a part of the enclosure that can be opened or removed by the user without using a tool (to attach an accessory, to make an operating adjustment, or for other reasons) is to be opened or removed.
6.8 With reference to 6.1 and 6.2, insulated brush caps are not required to be additionally enclosed.
7 Means for Mounting
7.1 A cord reel shall not be provided with means for permanent mounting if the reel is intended to be connected to the power supply by a means of flexible cord with an attachment plug. For this type of construction, the source of supply is connected at the hub of the cord reel. See 16.3.
Exception: A general-use cord reel provided with a flexible cord and attachment plug provided with a means for permanent mounting is acceptable if the flexible cord complies with 13.4.
7.2 The requirement in 7.1 does not preclude the permanent mounting of a special-use cord reel connected to the power supply by means of the retractable flexible cord. A cord terminated with an attachment plug is acceptable if the reel is also provided with means for permanent connection to the load, for example, a cord reel mounted on a mobile appliance. For this type of construction, the source of supply is connected at the unspooled cord.
7.3 With reference to 7.1, a keyhole slot, a notch, a hanger hole, or a hanger ring 1/2 in (12.7 mm) or
larger in diameter is not considered to be a means for permanent mounting. If a hanger ring is employed,
the hanger ring shall form a complete loop after the cord reel is mounted as intended. A separate bracket
intended for permanent attachment to a wall or other surface, to which the cord reel might be attached by
a removable swivel pin or similar device, is not considered to be a means for permanent attachment.
Revised 7.3 effective January 23, 2006
7.4 A cord reel that is intended for permanent connection to the power supply shall be provided with means for permanent mounting.
8 Bonding
8.1 All exposed dead-metal parts of a cord reel:
a) Intended for permanent connection to the power supply shall be bonded to the point on the reel to which the supply system will be connected, and to the equipment-grounding terminal or lead if such is provided on the reel.
Exception: This requirement does not apply to a dead-metal part of a load-end fitting of a reel employing a 2-wire cord.
b) Intended to be connected to the power supply by a cord employing an equipment-grounding conductor shall be bonded to the equipment-grounding conductor, or to the terminal to which
the equipment-grounding conductor will be connected if the cord is to be field installed.
9 Protection Against Corrosion
9.1 Iron or steel parts, other than stainless steel, shall be protected against corrosion by plating, galvanizing, enameling, or the equivalent.
10 Live Parts
10.1 Current-carrying parts shall be of copper, copper alloy, silver alloy, carbon composition, or other material rated for the purpose. Iron or steel shall not be used for current-carrying parts.
10.2 Uninsulated live parts shall be mounted and shall be prevented from turning by means other than friction between surfaces.
11 Overcurrent Protection
11.1 A cord reel employing or intended to be used with flexible cord having conductor sizes smaller than 16 AWG shall be provided with overcurrent protection (short-circuit and overload protection) unless.
