The answer to 'difference between surge protection' is that surge protectors and whole-home surge arresters are both devices that protect your home's electrical system from power surges, but they differ in their features, benefits, costs, and use cases. Surge protectors are plug-in devices that protect individual electronics or appliances, while whole-home surge arresters are permanently installed at the electrical panel to protect the entire home's wiring and connected devices.
Surge protectors are more affordable and portable, making them a good option for protecting valuable electronics like computers, TVs, and home entertainment systems. Whole-home surge arresters provide more comprehensive protection for the entire home, safeguarding against larger power surges that can damage the home's electrical infrastructure and multiple devices simultaneously. They are more expensive to install but offer long-term protection and peace of mind for homeowners.
