A RPT may include an integral Class 2

4、 power supply with anintegral lead and/or connector(s) output. RPT are for use as a movable power supply connection for cordand plug connected electrical utilization equipment in accordance with the National Electric Code, NFPA70.3 Glossary3.2.1 CLASS 2 LEAD - Consists of a factory-made, power-limit

5、ed cable with a connector at one end. Theother end is secured within the housing or enclosure of the RPT. The connector is intended for connectionto the Class 2 separable interface.3.2.2 CLASS 2 SEPARABLE INTERFACE A separable component containing Class 2 low-voltageconnector(s) only (such as Univer

7、Type CL2 cable in accordance with the Standard for Power-Limited Circuit Cables, UL 13b) An appliance wiring material with a maximum length of 10 feet (3.5 m), minimum of 26 AWG,rated minimum VW-1 flammability and minimum 300 V, in accordance with the Standard forAppliance Wiring Material, UL 758.11

8、.1.9 One end of a Class 2 lead shall be either molded-on or permanently attached to the RPT housingor enclosure.UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM UL11.1.10 The other end of a Class 2 lead shall terminate in a connector capable of b

The “Class 2” and output electrical rating shall be permanently marked andvisible after installation.RATIONALE FOR DECISION:UL 1363 permits a relocatable power tap to employ a Class 2 power supp

13、ly with low-voltage (such as USBoutputs). The Standard does not address a Class 2 power supply with low-voltage connectors where thelow-voltage connectors extend from the relocatable power tap housing by an insulated lead. The strainrelief pull values are based upon present pull force values for sim
