          Information is provided to specifiers and users of surge-protective devices (SPDs) about the application considerations of SPDs associated with power distribution systems within North America. This guide applies to SPDs to be connected to the load side of the service entrance main over current protective device of 50 Hz or 60 Hz ac power circuits rated at 100–1000 V rms. The effects and side effects on the presence and operation of SPDs in low-voltage power distribution systems are described. The coordination of multiple SPDs on the same circuit is described.<br />\n
          \t\t\t\t<br />\n
          The transient overvoltages or surge events that are described and discussed in this guide are those that originate outside of a building or facility and impinge on a power distribution system (PDS) through the service entrance conductors. Transient overvoltages or surge events that originate from equipment within a specific facility are not within the scope of this document.<br />\n
          This guide applies to surge-protective devices (SPDs) that are manufactured for connections to 50 Hz or<br />\n
          60 Hz ac power circuits that are rated between 100 V rms and 1000 V rms. This guide applies to SPDs that<br />\n
          are specifically identified, labeled, or listed for connections on the load side of the service entrance main<br />\n
          overcurrent protective device. This guide does not cover those SPDs identified, labeled, or tested as a<br />\n
          secondary surge arrester intended for connections on the line side of the service entrance main overcurrent<br />\n
          protective device.<br />\n
          The SPDs covered in this guide are those manufactured for use in an association with electrical power<br />\n
          distribution equipment such as load centers, motor control centers, panelboards, switchboards, switchgear,<br />\n
          and end-use equipment installed in commercial and industrial facilities. This guide excludes SPDs<br />\n
          associated with retail and consumer appliances and components for residential use.<br />\n
          This guide does not specify or set limits on insulation levels of any components associated with power<br />\n
          distribution systems or end-use equipment. In addition, it is not the intent of this guide to address individual<br />\n
          SPD component specifications associated with any specific manufacturer of surge protection products.The SPDs discussed in this guide contain at least one nonlinear component for either diverting surge currents<br />\n
          and/or dissipating surge energy. Examples of such nonlinear components are metal-oxide varistors (MOVs),<br />\n
          silicon avalanche diodes (SADs), spark gap tubes, or thyristors. Ferroresonators, motor-generators, uninterruptible<br />\n
          power supplies, and filters containing only inductive or capacitive components are not considered SPDs in the<br />\n
          guide.<br />\n
          The primary purpose of an SPD is to provide a desirable level of surge protection by diverting surge currents and by reducing surge voltages to a level that can be tolerated by the PDS and the equipment connected to the system.<br />\n
          When specifying and installing any SPD in low-voltage power distribution equipment associated with commercial and industrial installations, numerous application considerations should be reviewed and evaluated before installation. Failure to consider the applications or misapplications of any SPD can directly influence the expected performance of the SPD and can result in undesirable effects on a PDS and/or end-use equipment. It is the intent of this guide to inform specifiers and users of SPDs, such as specifying engineers, electrical inspectors, facilities engineers, or authorities having jurisdiction, of application and installation considerations for the purpose of desirable and satisfactory application of SPDs.

          New IEEE Standard - Superseded.<br />\n
          Information is provided to specifiers and users of surge-protective devices (SPDs) about the application considerations of SPDs associated with power distribution systems within North America. This guide applies to SPDs to be connected to the load side of the service entrance main over current protective device of 50 Hz or 60 Hz ac power circuits rated at 100–1000 V rms. The effects and side effects on the presence and operation of SPDs in low-voltage power distribution systems are described. The coordination of multiple SPDs on the same circuit is described.<br />\n
          \t\t\t\t<br />\n
          The transient overvoltages or surge events that are described and discussed in this guide are those that originate outside of a building or facility and impinge on a power distribution system (PDS) through the service entrance conductors. Transient overvoltages or surge events that originate from equipment within a specific facility are not within the scope of this document.<br />\n
          This guide applies to surge-protective devices (SPDs) that are manufactured for connections to 50 Hz or<br />\n
          60 Hz ac power circuits that are rated between 100 V rms and 1000 V rms. This guide applies to SPDs that<br />\n
          are specifically identified, labeled, or listed for connections on the load side of the service entrance main<br />\n
          overcurrent protective device. This guide does not cover those SPDs identified, labeled, or tested as a<br />\n
          secondary surge arrester intended for connections on the line side of the service entrance main overcurrent<br />\n
          protective device.<br />\n
          The SPDs covered in this guide are those manufactured for use in an association with electrical power<br />\n
          distribution equipment such as load centers, motor control centers, panelboards, switchboards, switchgear,<br />\n
          and end-use equipment installed in commercial and industrial facilities. This guide excludes SPDs<br />\n
          associated with retail and consumer appliances and components for residential use.<br />\n
          This guide does not specify or set limits on insulation levels of any components associated with power<br />\n
          distribution systems or end-use equipment. In addition, it is not the intent of this guide to address individual<br />\n
          SPD component specifications associated with any specific manufacturer of surge protection products.The SPDs discussed in this guide contain at least one nonlinear component for either diverting surge currents<br />\n
          and/or dissipating surge energy. Examples of such nonlinear components are metal-oxide varistors (MOVs),<br />\n
          silicon avalanche diodes (SADs), spark gap tubes, or thyristors. Ferroresonators, motor-generators, uninterruptible<br />\n
          power supplies, and filters containing only inductive or capacitive components are not considered SPDs in the<br />\n
          guide.<br />\n
          The primary purpose of an SPD is to provide a desirable level of surge protection by diverting surge currents and by reducing surge voltages to a level that can be tolerated by the PDS and the equipment connected to the system.<br />\n
          When specifying and installing any SPD in low-voltage power distribution equipment associated with commercial and industrial installations, numerous application considerations should be reviewed and evaluated before installation. Failure to consider the applications or misapplications of any SPD can directly influence the expected performance of the SPD and can result in undesirable effects on a PDS and/or end-use equipment. It is the intent of this guide to inform specifiers and users of SPDs, such as specifying engineers, electrical inspectors, facilities engineers, or authorities having jurisdiction, of application and installation considerations for the purpose of desirable and satisfactory application of SPDs.

          New IEEE Standard - Superseded.<br />\n
          Information is provided to specifiers and users of surge-protective devices (SPDs) about the application considerations of SPDs associated with power distribution systems within North America. This guide applies to SPDs to be connected to the load side of the service entrance main over current protective device of 50 Hz or 60 Hz ac power circuits rated at 100–1000 V rms. The effects and side effects on the presence and operation of SPDs in low-voltage power distribution systems are described. The coordination of multiple SPDs on the same circuit is described.<br />\n
          \t\t\t\t<br />\n
          The transient overvoltages or surge events that are described and discussed in this guide are those that originate outside of a building or facility and impinge on a power distribution system (PDS) through the service entrance conductors. Transient overvoltages or surge events that originate from equipment within a specific facility are not within the scope of this document.<br />\n
          This guide applies to surge-protective devices (SPDs) that are manufactured for connections to 50 Hz or<br />\n
          60 Hz ac power circuits that are rated between 100 V rms and 1000 V rms. This guide applies to SPDs that<br />\n
          are specifically identified, labeled, or listed for connections on the load side of the service entrance main<br />\n
          overcurrent protective device. This guide does not cover those SPDs identified, labeled, or tested as a<br />\n
          secondary surge arrester intended for connections on the line side of the service entrance main overcurrent<br />\n
          protective device.<br />\n
          The SPDs covered in this guide are those manufactured for use in an association with electrical power<br />\n
          distribution equipment such as load centers, motor control centers, panelboards, switchboards, switchgear,<br />\n
          and end-use equipment installed in commercial and industrial facilities. This guide excludes SPDs<br />\n
          associated with retail and consumer appliances and components for residential use.<br />\n
          This guide does not specify or set limits on insulation levels of any components associated with power<br />\n
          distribution systems or end-use equipment. In addition, it is not the intent of this guide to address individual<br />\n
          SPD component specifications associated with any specific manufacturer of surge protection products.The SPDs discussed in this guide contain at least one nonlinear component for either diverting surge currents<br />\n

          power supplies, and filters containing only inductive or capacitive components are not considered SPDs in the<br />\n
          guide.<br />\n
          The primary purpose of an SPD is to provide a desirable level of surge protection by diverting surge currents and by reducing surge voltages to a level that can be tolerated by the PDS and the equipment connected to the system.<br />\n
          When specifying and installing any SPD in low-voltage power distribution equipment associated with commercial and industrial installations, numerous application considerations should be reviewed and evaluated before installation. Failure to consider the applications or misapplications of any SPD can directly influence the expected performance of the SPD and can result in undesirable effects on a PDS and/or end-use equipment. It is the intent of this guide to inform specifiers and users of SPDs, such as specifying engineers, electrical inspectors, facilities engineers, or authorities having jurisdiction, of application and installation considerations for the purpose of desirable and satisfactory application of SPDs.

          Information is provided to specifiers and users of surge-protective devices (SPDs) about the application considerations of SPDs associated with power distribution systems within North America. This guide applies to SPDs to be connected to the load side of the service entrance main over current protective device of 50 Hz or 60 Hz ac power circuits rated at 100–1000 V rms. The effects and side effects on the presence and operation of SPDs in low-voltage power distribution systems are described. The coordination of multiple SPDs on the same circuit is described.<br />\n
          \t\t\t\t<br />\n
          The transient overvoltages or surge events that are described and discussed in this guide are those that originate outside of a building or facility and impinge on a power distribution system (PDS) through the service entrance conductors. Transient overvoltages or surge events that originate from equipment within a specific facility are not within the scope of this document.<br />\n
          This guide applies to surge-protective devices (SPDs) that are manufactured for connections to 50 Hz or<br />\n
          60 Hz ac power circuits that are rated between 100 V rms and 1000 V rms. This guide applies to SPDs that<br />\n
          are specifically identified, labeled, or listed for connections on the load side of the service entrance main<br />\n
          overcurrent protective device. This guide does not cover those SPDs identified, labeled, or tested as a<br />\n
          secondary surge arrester intended for connections on the line side of the service entrance main overcurrent<br />\n
          protective device.<br />\n
          The SPDs covered in this guide are those manufactured for use in an association with electrical power<br />\n
          distribution equipment such as load centers, motor control centers, panelboards, switchboards, switchgear,<br />\n
          and end-use equipment installed in commercial and industrial facilities. This guide excludes SPDs<br />\n
          associated with retail and consumer appliances and components for residential use.<br />\n
          This guide does not specify or set limits on insulation levels of any components associated with power<br />\n
          distribution systems or end-use equipment. In addition, it is not the intent of this guide to address individual<br />\n
          SPD component specifications associated with any specific manufacturer of surge protection products.The SPDs discussed in this guide contain at least one nonlinear component for either diverting surge currents<br />\n
          and/or dissipating surge energy. Examples of such nonlinear components are metal-oxide varistors (MOVs),<br />\n
          silicon avalanche diodes (SADs), spark gap tubes, or thyristors. Ferroresonators, motor-generators, uninterruptible<br />\n

          This standard applies to surge-protective devices (SPDs) intended to be installed on the load side of the service equipment connected to 50 Hz or 60 Hz alternating current (ac) power circuits rated at 1000 V (root mean squared [rms]) or less. Performance characteristics and standard methods for testing and rating are established for these devices, which may be composed of any combination of components. The tests in this standard are aimed at providing comparisons among the variety of surge-protective devices available.<br />\n
          The purpose of this standard is to provide users, independent laboratories, and manufacturers with test methods and test specifications applicable to low-voltage surge-protective devices used on the load side of the service equipment, intended for limiting transient overvoltages that can appear on ac power circuits of 1000 V (rms) or less.
