About NEMA Surge Protection Institute

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.

What are Surges?

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.
