Installed whole-home surge protection in a residential property. Mounted a Type 2 surge protection device (SPD) near the main electrical panel and connected it to a dedicated 20-amp breaker. Ensured all grounding connections were secure and compliant with NEC standards. Tested the SPD for correct operation, ensuring it effectively protects against transient voltage spikes. This setup safeguards all home electronics and appliances from electrical surges and potential damage.
