The ground pin slot of a receptac

27、le is to be at the top. The devices 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

28、 the normal mounting position. 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).

29、 FURTHER REPRODUCTION OR DISTRIBUTION 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 u

30、sing supply conductors having 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

31、connection of feed-through conductors. 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 produc

32、t performs its normal function. See Figure 5.2 This is generated text for gtxt.

33、ice mentioned in 5.7, modied 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 equiva

34、lent means, meet the intent of 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 wir

35、e binding screws shall be formed 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

36、 1/2 of the diameter of the test 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.

37、FURTHER REPRODUCTION OR DISTRIBUTION 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

38、to minimize the transmission 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 w

39、ire disturbance test. For example, 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

40、3.3 mm 2 ) conductor wire insulation 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

41、 in a substantially draft-free 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 use

42、d whenever referee temperature measurements are required. Thermocouples shall be placed close to the point of maximum heating of the terminal.

43、FROM UL 5.13 In applying 5.12, 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 t

44、hermocouple is to be placed on 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 i

45、ntent of the requirement. 5.14 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-Electromotiv

46、e Force (emf) Tables for Standardized 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

47、measured in the immediate vicinity 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) Us

48、ing 10 AWG (5.3 mm 2 ) test wire 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

49、branch circuit, as in a duplex 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 not exceed 100C (180F) and the stability factor (see 6.7) shall not exceed 10 (18 when temperatures are mea
