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.

Guide for the Application of Plug-in Multiservice Surge-Protective Devices (MSPDs) for Equipment Connected to AC Mains and Information and Communication Technology (ICT) Metallic Cables
This Guide considers the ramifications of deploying multiservice surge protective devices (MSPDs) as specified in C62.50: Standard for Performance Criteria and Test Methods for Plug-in (Portable) Multiservice (Multiport) Surge-Protective Devices for Equipment Connected to a 120/240 V Single Phase Power Service and metallic conductive communication line(s). Topics covered are: * MSPD protected and unprotected side port overvoltage conditions * Ground/earth potential rise effects * Stress levels of items connected to the MSPD unprotected side ports * Use of multiple MSPDs * Simulations of premises surge conditions.
