Just for clarification, Type-1 Surge protectors are installed at the service entrance, directly connected without a circuit breaker. Type-2 surge protectors are installed at the circuit breaker panel with a circuit breaker. This is important because the surge protector is designed differently for each application. Typically, premium surge protectors such as the Eaton Ultra or the PSP Vortex should provide enough protection when installed at the circuit breaker panel. The Seco protector installed at the meter is specifically designed to block and or manage very large surges originating from the power utility which is why it's warranty does not cover any device in your home with an electronic chip installed. Having both gives you the layered protection that's recommended. Although the new electrical code requires Type-1/2 surge protection, we would need to know exactly what was installed in these new homes to determine if an additional Type-2 protector would be beneficial. If you PM me, I would be happy to stop by and see what they installed.
