The Electrical Safety Foundation and The National Electrical Manufacturers Association’s (NEMA) Low Voltage Surge Protective Devices Section (BI-VS) recently released a series of videos highlighting the causes of power surges and detailing the benefits of installing surge protective devices to protect businesses and facilities.
This guide serves primarily for those who use or specify Surge Protective Devices to provide uniformity of specifications, understandable parameters, as well as improved comprehension, application, and utilization of SPDs.
The 2020 NEC contains increased requirements for the use of Sure Protective Devices to include dwelling units.
Surges can damage, degrade, or destroy sensitive electronic equipment in offices or businesses. NEMA has shown that all electrical products, sensors, and systems containing electronic components are at risk of suffering damage from electrical surges.
The NEMA Surge Protection Institute (NSPI) is an educational outreach effort initiated by the Low Voltage Surge Protective Devices Section of the National Electrical Manufacturers Association (NEMA), a not-for-profit trade association. Our mission is to heighten awareness of the benefits of surge protection to all users of low voltage electrical systems in North America for the purpose of promoting proper application and usage.
Surges, or transients, are brief overvoltage spikes or disturbances on a power waveform that can damage, degrade, or destroy electronic equipment within any home, commercial building, industrial, or manufacturing facility. Transients can reach amplitudes of tens of thousands of volts. Learn more.
This guide is the first in a new series intended to guide the evaluation, specification, and use of SPD’s deployed in low-voltage power distribution system applications. | Download
The purpose of this paper is to present the test results of actual devices in a real-world surge environment and will generate information on the surge susceptibility for various electrical components. | Download
The intent of this paper is not to evaluate the safety and/or product performance of companies installed electrical systems, but to create awareness and offer guidance based on real-world testing of protection that will help prevent problems with products. | Download
