5.9 Spacings
5.9.1 There shaH be a spacing through air or over surface of not less than 1.2 mm (3/64 inch) for a device rated 250 V or less, and not less than 3.2 mm (1/8 inch) for a device rated greater than 250 V, between uninsuLated live parts and dead-metal paris that are likely to be grounded or exposed to contact by persons when the device is installed as intended.
5.9.2 The dead metal mentioned in 5.9.1 includes a metal surface on which the device Is mounted in the intended manner. A dead-metal screw head, rivet, or the like is not considered to be exposed to contact by persons after the device is installed in the intended manner, it the dead metal is located in a hole not larger than 7.1 mm (9/32 inch) in diameter and recessed not less than 4.8 mm (3/16 inch).
5.9.3 In measuring a spacing, an isolated dead-metal part interposed between live parts of opposite polarity, or between a live part and a grounded or exposed dead-metal part, Is considered to reduce the spacing by an amount equal to the dimension of the isolated dead-metal part in the direction of the measurement.
5.10 Assembly
5.10.1 A device shall be capable of being readily wired as intended.
5.10.2 Electrical contact shall be reliably maintained at any point at which a connection is made between currentcarrying pails.
5.10.3 An outlet device shall have live parts protected against unmtentional contact by persons when the outlet is assembled and installed as intended.
5.10.4 Means shall be provided for securely attaching the contact of a panel inlet or outtet to the mounting base. The contact shall be prevented from turning with respect to the mounting base.
5.10.5 Panel inlets and outlets shall be provided with at least two independent mechanical means of fixation to prevent rotation or movement, when assembled to a panel in the intended manner.
5,10.6 A metal-covered device intended for connection to a flexible cord shall be provided with an insulating bushing.
5.11.2 relocated as 5.10.8
5.107 A bushing made of hard fiber is acceptable it the fiber is not less than 1.2 mm (3/64 inch) thick and It Is so formed and secured in place that it will not be affected by ordinary conditions of moisture.
5,11.3 relocated as 510,7
5.10.8 If the metal covering of a device is not In proximity to the cord-entry hole, and the insulating material of which the connector is made serves as a smooth, well-rounded bushing for a flexible cord or cable, a separate bushing is not required.
6.2 Comparative tracking index test
6.2.1 A polymeric material used for electrical insulation, an internal barrier necessary to maintain electrical spacings, or an enclosure of live parts tested in accordance with the Comparative Tracking Index and Comparative Tracking Performance Level Class of Electrical Materials test described in the Standard for Polymeric Materials — Short Term Property Evaluations. UL 746A, shall have a performance level class value not greater than 3. See also 53.3.
6.2.2 Notwithstanding 6.2.1, a polymeric material having a maximum Comparative Tracking Index (CTI) performance level class of 3 or a minimum CTI value of 175 need not be subjected to the test.
6.3 Glow wire test
6.3.1 A polymeric material used for electrical insulation, an internal barrier necessary to maintain electrical spacings, or an enclosure of live parts shall be tested in accordance with the requirements of 6.3.2 in order to determine its resistance to ignition from overheated conductors caused by circuit overloads.
6.3.2 Notwithstanding 6.3.1, a polymeric material having Hot Wire Ignihon (HWI) performance level class values not greater than those shown in Table ifor the applicable flammability classification need not be subectod to the Glow Wire Test. 6.3.3.
6.3.3 Devices shall be subjected to the Glow-Wire Resistance to Ignition Test described in the Standard for Polymeric Materials — Short Term Properly Evaluations, UL 746A or CSA C22.2 No. 0.17, As a result of this test, there shall not be Ignition of the Insulating material during 30 seconds of application of the probe.
