What is the main consideration when installing SPDs at service entrances?

The primary consideration when installing Surge Protective Devices (SPDs) at service entrances is compliance with safety standards. This is crucial because safety standards ensure that the installation adheres to established guidelines and regulations designed to protect both the electrical system and the people using it. By following these standards, one can minimize the risk of electrical fires, equipment damage, and personal injury that could result from surges or lightning strikes.

While factors such as cost reduction, aesthetics, and connection quality are important in an overall project, they should not overshadow the foundational necessity of meeting safety standards. Proper compliance assures that the installation is reliable and effective, protecting the system and ensuring that it operates correctly within the defined regulatory framework.
