The scope of this standard is to define performance criteria and test methods for plug-in (portable) multiservice (multiport) surge protective devices (MSPDs) intended to protect equipment connected to one or more metallic conductive communication line(s) and a 120 V/240 V single phase ac power service, with the neutral grounded at the service equipment. These devices are intended for installation at receptacles supplying power via a branch circuit of the installation, and jointly at receptacles or jacks delivering signals from communications services, for the purpose of providing protected power and signals to a variety of information technology equipment.
The purpose of this project is to provide a uniform specification/test document for design and application engineers, specifiers, and test laboratories to use in designing and testing this type of surge protective device.
New IEEE Standard – Inactive-Reserved. Test methods and performance criteria for plug-in (portable) multiservice (multiport) surge protective devices (MSPDs) intended to protect equipment connected to one or more metallic conductive telecommunication line(s) and a 120 V/240 V single phase two-wire (line and neutral) ac power service, with the neutral grounded at the service equipment are defined in this standard. Performance testing covers three areas: the ac power SPD section, the telecommunication SPD section, and the MSPD as whole. Essential MSPD performance characteristics are the reduction of surge current in the equipment ground loops and surge coupling between the individual SPD sections.
