SPD Surge Protective Devices are ingeniously crafted to shield against transient surge conditions. These devices stand as a formidable defense against large single surge events, like the mighty strike of lightning, which can unleash hundreds of thousands of volts, posing immediate or intermittent threats to equipment functionality. Interestingly, lightning and utility power anomalies contribute to only 20% of transient surges. The remaining 80% of surges are generated internally. While these internal surges might be smaller, their frequency and persistent exposure pose a significant risk, potentially degrading sensitive electronic devices within the facility.
A power surge is a fleeting overvoltage incident that has the potential to harm electrical devices and is a prevalent cause behind the malfunctioning of electrical equipment. Such surges can inflict damage and shorten the lifespan of:
NEW 2020 National Electrical Code Requirements
All new and newly renovated homes must now adhere to the 2020 code requirements by being equipped with Listed and Approved Type 1 or Type 2 Surge Protective Devices, ensuring a robust shield against unforeseen surges.
Type 1:
This Type 1 Surge Protective Device is a permanently connected shield, offering robust protection against both external and internal surges. Its versatile installation allows it to be placed inside or outside the home for optimal defense.
Type 2:
The Type 2 Surge Protective Device is also permanently connected, strategically installed in or next to the breaker box. It provides unwavering protection against both internal and external surges.
Type 3:
For enhanced security, the Type 3 device offers extra protection. As a point-of-use Surge Protective Device, it must be used alongside Type 1 or Type 2 SPDs to satisfy the 2020 code requirements.
For comprehensive protection, employing a combination of Type 1, 2, and 3 SPDs ensures the highest level of safety and peace of mind.
