21、 of branch circuit wiring and Class 2connections;Figure 86.1Test setupNOTE Duplex receptacle shall be wired as intended and installed into the outlet box.STANDARD NUMBER: UL 1310 -3-UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULb) Not permit

22、 contact to be made between the probes shown in Figure 16.1, Figure 16.2, orFigure 16.4 and any live part through the Class 2 output connectors or through any opening orjoint surrounding the installed device; andc) Not permit contact to be made between the Class 2 output connector and receptacle lin

23、econtacts with an ANSI/NEMA 1-15P attachment plug.87.2 The device shall be checked for compliance with 87.1(a). Following assembly to the test setup FigureSA6.1, the device shall be checked for compliance with 87.1(b). The probes of Figure 16.1, 16.2 and 16.4are to be applied to any opening or joint

24、 surrounding the Class 2 output and through the Class 2 outputconnector slot openings with a force of 8 ounces (2.2 N) in attempt to contact live parts. A suitableindicating device (such as an ohmmeter, battery-and-buzzer combination, or similar device) is to beconnected between the probe and the wi

25、ring terminal of the receptacle to determine whether contact ismade. The probes are to be inserted in the Class 2 output connector slot opening successively in threedirections in any orientation that may permit access to contact live parts. The probes are to be applied forapproximately 5 seconds in

26、each of the three directions. During each application, the probes shall not bemoved or rotated and shall be withdrawn when moving from one direction to the next.87.3 The same representative assembly as described in 87.2 shall be checked for compliance with87.1(c), using an ANSI/NEMA 1-15P polarized

27、attachment plug. One blade shall be inserted into the slotopenings of the Class 2 output connector and the other blade into the slot openings of the receptaclecontacts with a force of 10 pounds (45 N) in an attempt to contact live parts. A suitable indicating device(such as an ohmmeter, battery-and-

28、buzzer combination, or similar device) is to be connected between theClass 2 output connector and the contacts of the receptacle to determine whether contact is made. Theattachment plug is to be manipulated in any direction or orientation that may permit access to contact liveparts. The attachment p

29、lug is applied for approximately 5 seconds in each direction.88 Installation Instructions88.1 Installation instructions shall appear on the device, on the smallest unit container, or on a separateinstruction sheet provided with each device. If the installation instructions are provided on the smalle

30、st unitcontainer or on a separate sheet, they shall be attached to the device in such a manner that they areunable to become detached during normal conditions of handling and storage prior to initial installation orusage. The use of an individual carton, blister pack, or equivalent securing of the d

31、evice to theinstructions, meets the intent of the requirement. However, friction attachment shall not be employed.88.2 A device intended for installation with receptacle cover plate or cover plate screw removed shall beprovided with detailed installation instructions to enable proper installation of

32、 the device with the coverplate removed. The inclusion of a pictorial representation is optional.88.3 A device intended for installation over receptacle cover plates of specific dimensions shall beprovided with installation instructions that describe the maximum overall dimensions of the receptaclec

33、over plate with which the device is intended to be used.88.4 A device having blade spacing not in accordance with Standard for Current Taps and Adapters, UL498A, Figure 9.1, shall be provided with installation instructions that specify, by catalog number orequivalent designation, the receptacles wit

34、h which the device is to be used.88.5 Instructions shall include information to alert the user that a single branch circuit shall supply thedevice. The instructions shall include a pictorial or photograph illustrating proper installation.89 MarkingsSTANDARD NUMBER: UL 1310 -4-UL COPYRIGHTED MATERIAL
