Category: Start Here

Start here if you are deciding whether whole-home surge protection belongs in your electrical plan or trying to understand what the equipment actually does. These guides explain transient overvoltage, Type 1, Type 2, and Type 3 protection, the difference between panel and point-of-use devices, code context, lightning limits, and the tradeoffs behind a layered system. They do not treat an SPD as a guarantee or a repair for grounding, bonding, wiring, sustained voltage problems, or a complete lightning-protection system. Begin with the homeowner’s guide, then use the type comparison and need-assessment articles to identify the questions that apply to your house. Panel- and service-connected products require compatibility review and qualified installation; the educational path here helps you prepare without opening the panel or guessing from a product label.
