20、y noted in this document. The standard may not use all types of thesedeviations.DR - These are deviations based on the National Electrical Code (NEC) and other U.S. RegulatoryRequirements.D1 - These are deviations which are based on basic safety principles and requirements, elimination ofwhich would

21、 compromise safety for U.S. consumers and users of products.D2 - These are deviations based on safety practices. These are deviations for IEC requirements that maybe acceptable, but adopting the IEC requirements would require considerable retesting or redesign on themanufacturers part.DC - These are

22、 deviations based on the component standards and will not be deleted until a particularcomponent standard is harmonized with the IEC component standard.DE - These are deviations based on editorial comments or correctionsJANUARY 16, 2004NATIONAL DIFFERENCES FOR UL UL 60730-2-184UL COPYRIGHTED MATERIA
