- Surge protection ratings
- Understanding the Arrester The two most important factors used to select an arrester rating are the system voltage and the neutral grounding configuration of the source transformer.
- Understanding Surge Protective Device Ratings The surge rating or kA rating of an SPD is one of the most misunderstood ratings. Customers commonly ask for an SPD to protect their 200A panel. There's also a tendency to think that the larger the panel, the larger the kA device rating needs to be for protection.
