SPD Surge Protective Devices are the vigilant guardians of your valuable electronics, meticulously engineered to defend against transient surge events that can wreak havoc on your equipment. While notorious large surges like lightning surges can unleash hundreds of thousands of volts, leading to immediate or sporadic equipment failures, these account for only 20% of all transient surges. The true culprits, responsible for 80% of surges, are born within the very walls of your facility. Though more modest in intensity, these frequent internal surges pose a significant threat over time, stealthily eroding the integrity of sensitive electronics.
A power surge is a fleeting spike in voltage that, despite its brief nature, harbors the potential to inflict severe damage on electrical devices and stands as a primary culprit in the premature failure of electrical equipment. The havoc wreaked by surges extends to and shortens the lifespan of:
NEW 2020 National Electrical Code Requirements
In a commitment to safeguarding our homes, the 2020 National Electrical Code mandates that all new and renovated homes must be fortified by Listed and Approved Type 1 or Type 2 Surge Protective Devices.
Type 1:
A robust, permanently connected Surge Protective Device, Type 1 provides comprehensive defense against both external and internal surges. Designed for versatility, it can be installed either indoors or outdoors, offering a steadfast shield for your home.
Type 2:
This reliable, permanently connected Surge Protective Device is strategically installed in or adjacent to the breaker box. Type 2 SPDs excel at guarding against both internal and external surges, ensuring a secure environment for your electrical systems.
Type 3:
Offering an added layer of security, the Type 3 Surge Protective Device is a point-of-use defender. To meet the stringent 2020 code requirements, it must be used in conjunction with Type 1 or Type 2 SPDs, amplifying your protection strategy.
For unparalleled security and peace of mind, employ the power of Type 1, 2, and 3 SPDs together, ensuring the ultimate safeguard for your valued electronics.

Selection of SPD:
For ensuring utmost safety and efficiency in a power distribution system, the pivotal characteristics for defining a robust lightning protection system and selecting an appropriate SPD to safeguard an electrical installation in a building encompass the following:
The additional characteristics essential for the selection of a SPD are pre-established for an electrical installation, ensuring optimal performance and safety.
This sub-section Design of the Electrical Installation Protection System elaborates comprehensively on the criteria for adeptly selecting the protection system in accordance with the distinct characteristics of the installation, the equipment poised for protection, and the surrounding environment.
Location and Types of SPD:
Connection of SPD:
For optimal functionality, ensure that connections of a SPD to the loads are as succinct as possible, minimizing the value of the voltage protection level (installed Up) at the terminals of the protected equipment.
The cumulative length of SPD connections to the network and the earth terminal block must not surpass 50 cm, ensuring efficiency and safety.
