14、 FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover wire binding screw terminals of receptacles and switches rated 15 or 20 A intended for use with solid conductor aluminum building wire, and that require direct connection of wiring

15、conductor(s) to the binding head screw terminal(s) prior to insertion of the device in an outlet box. 1.2 These performance requirements for wire binding screw terminals are in addition to the requirements for the products covered by the Standard for Attachment Plugs and Receptacles, UL 498, and the

16、 Standard for General-Use Snap Switches, UL 20. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this Standard shall comply with the requirements for that component. 2.2 A component need not comply with a specic requirement that: a) Involves a feature or characteristi

17、c not needed in the application of the component in the product covered by this Standard, or b) Is superseded by a requirement in this Standard. 2.3 A component shall be used in accordance with its recognized rating established for the intended conditions of use. 2.4 Specic components are recognized

18、 as being 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 restricted to use only under those specic conditions for which they have

19、 been recognized. 3 Units of Measurement 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information.

PERFORMANCE 5 General 5.1 Test Wire Size Products rated 15 or 20 A shall be investigated for use with 12 (3.3 mm

21、2 ) and 10 AWG (5.3 mm 2 ) aluminum conductors when they are intended for use on branch circuits protected by overcurrent protection rated either 15 or 20 A in accordance with the National Electrical Code (NEC) ANSI/NFPA-70. Products rated 20 A shall be investigated for use with 10 AWG wire. Product

22、s rated 15 A that are not intended for use on a 20-A branch circuit shall be investigated with 12 AWG wire. 5.2 Test Wire Characteristics The aluminum test wire shall be thermoplastic insulated building wire, Type TW or THW. The conductor shall be EC alloy 1350 aluminum having the characteristics in

23、dicated in Table 5.1 with an ultimate tensile strength of 17000 21000 lbf/in 2 (117.2 144.8 MPa), a minimum percentage elongation of 7 and a maximum percentage elongation of 10. The test conductor shall be drawn from 3/8 inch (9.5 mm) diameter rod to the nished size without any intermediate annealin

24、g. The conductor shall be batch annealed with air atmosphere to obtain the physical characteristics.

The ground pin slot of a receptacle is to be at the top. The d

26、evices shall be secured to special test frames in a normal position of mounting, arranged to minimize the transfer of heat from adjacent terminals. The position of the terminal surface shall be vertical so as to permit free air ow across the terminal when consistent with the normal mounting position

27、. Any specic marked mounting position of the device shall be observed. The devices mounting strap shall be thermally insulated from the test frame to minimize heat transfer from the terminals. (See 6.10). MARCH 16, 2012 UL 1567 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DIST

28、RIBUTION WITHOUT PERMISSION FROM UL 5.4 Test Connections The devices are to be connected in a circuit using the appropriate gauge and interconnecting lead lengths specied in the individual tests. 5.5 The test circuit is to be connected to a regulated 60 Hz power supply using supply conductors having

29、 an ampacity at least that of the test current. 5.6 Where the construction of the product terminals meets the intent of the requirement for through connection, such as a duplex receptacle with two terminal screws per terminal, the product terminals shall be utilized for connection of feed-through co

30、nductors. See Figure 5.1. This is generated text for gtxt. 5.7 When the product terminal construction precludes through connection of wiring, such as a switch with a single terminal screw per terminal, the test wires shall be connected to the product such that the product performs its normal functio

Figure 5.1 Wiring for through connection terminal examples MARCH 16, 2012 UL 1567 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 5.8 In order to evaluate a device mentioned in 5.7, modied

32、devices are not prohibited when unrelated variables inuence the test results. For example, in order to obtain a through connection, switch contacts and internal current carrying parts of a receptacle bonded, jumpered by a soldered 14 AWG (2.1 mm 2 ) copper wire or equivalent means, meet the intent o

33、f the requirement. Modications are not to provide any increase in overall thermal or electrical conductivity, mechanical strength and so forth, beyond that of the basic unmodied device construction. 5.9 The end of the aluminum test wires to be connected to the device wire binding screws shall be for

34、med in a plane to have a 180 degree bend. The inside diameter of the bend shall be equal to 0.02 inch (0.5 mm) more than the nominal diameter of the device terminal screw. The end of the conductor shall not project from under the head of the screw more than approximately 1/2 of the diameter of the t

35、est conductor. A conductor forming jig shall be used to facilitate wiring in a reproducible fashion (see Figure 5.3). This is generated text for gtxt.

36、IBUTION WITHOUT PERMISSION FROM UL 5.10 The insulation of the test wire shall be removed in order to expose 1/4 inch (6.4 mm) of conductor beyond the head of the binding screw. Exception: When the device incorporates provisions, such as wire guides or channels, intended to minimize the transmission

37、of wire bending forces to the terminals, as in the case of a device that is wired and then moved into place, the length of the exposed conductor beyond that necessary to make the connection shall be selected so as to result in the least favorable test condition for the wire disturbance test. For exa

38、mple, a wire guide intended to accept an insulated conductor is to be tested with the wire insulation stripped back beyond the wire guide, and a wire guide intended to accept a 12 (3.3 mm 2 ) and a 10 AWG (5.3 mm 2 ) uninsulated conductor is to be tested with the 12 AWG (3.3 mm 2 ) conductor wire in

39、sulation not removed in the area of the guide when the guide accepts the insulated conductor. 5.11 Temperature Measurements Those parts of the test program that require measurement of the terminal temperatures generated by current ow through the device shall be conducted in a substantially draft-fre

40、e location. The room ambient temperature shall be maintained between 20 and 35C (68 and 95F). 5.12 Temperatures shall be measured using thermocouples as described in 5.14 and an appropriate indicating instrument. A potentiometer type of indicating instrument is to be used whenever referee temperatur

41、e measurements are required. Thermocouples shall be placed close to the point of maximum heating of the terminal.

42、, exploratory tests to determine the accessible point where maximum heating occurs are not prohibited. Thermocouples are to be located so as not to interfere with any wire disturbance test. On devices that meet the intent of the requirement for through connections, the thermocouple is to be placed o

43、n the break-off strap (if provided) or between the terminal screws of a solid plate. When the terminal plate is recessed or otherwise inaccessible, placing the thermocouple on the terminal screw or conductor, whichever results in the highest temperature rise, meets the intent of the requirement. 5.1

44、4 Thermocouples are to consist of 30 AWG (0.05 mm 2 ) iron and constantan wire. The thermocouple wire shall conform with the requirements specied in the Tolerances on Initial Values of EMF versus Temperature tables in the Standard Specication and Temperature-Electromotive Force (emf) Tables for Stan

45、dardized Thermocouples, ANSI/ASTM E230/E230M. 5.15 All temperature measurements shall be made after thermal equilibrium has been achieved. Thermal equilibrium occurs within the rst 2-3/4 hours of the 3-1/2 hour on part of the heat cycle. The ambient temperature shall be measured in the immediate vic

46、inity of the device under test at a point that is not affected by the heat from the device and its wiring. 6 Heat Cycling 6.1 A wire binding screw terminal shall be subject to a heat cycling test. Twenty-four wire binding screw terminal connections shall be tested: a) Using 10 AWG (5.3 mm 2 ) test w

47、ire with a test current of 53 A for device terminals rated 20 A. b) Using 12 AWG (3.3 mm 2 ) test wire with a test current of 40 A for device terminals rated 15 A. Exception: When a product terminal rated 15 A is such that it is also capable of being connected to a 20 A branch circuit, as in a duple

48、x receptacle, a second set of 24 terminal connections shall be tested using 10 AWG (5.3 mm 2 ) test wire at 53 A. 6.2 The test current through the terminals shall be cycled 3-1/2 hours on and 1/2 hour off for 500 cycles. The temperature rise at any time during the heat cycling on a terminal shall no

49、t exceed 100C (180F) and the stability factor (see 6.7) shall not exceed 10 (18 when temperatures are measured in degrees F). Exception: When the temperature rise exceeds 100C (180F) on any one or more terminals and does not exceed 125C (225F), the heat cycling shall be continued until 1000 cycles are completed as intended. When the temperature rise exceeds 125C (225F) and does not exceed 150C (270F), the heat cycling shall be
