The answer
Yes. Up to 80% of surges originate internally from cycling motors. Type 1/Type 2 panel-mounted SPDs divert high-voltage spikes to ground, protecting all hardwired appliances, while Type 3 plug-in strips protect fine electronics. NEC 230.67 mandates Type 1/2 SPDs on all new and upgraded residential services.
