BLOG The Essential Guide to Whole House Surge Protectors Sep 27, 2024

A service entrance rated whole home surge protector is a device designed to protect your entire household electrical system from power surges.

Here's how it works:

1. Installation Point:

This surge protector is typically installed at the main electrical panel, also known as the service entrance panel, where electricity from the utility company enters your home

2. Protection Scope:

Unlike individual surge protectors that you might plug into outlets, a whole home surge protector guards all the electrical devices and appliances connected to your home's wiring. This includes everything from major appliances like refrigerators and HVAC systems to sensitive electronics like computers and TVs.

3. Surge Absorption:

When a power surge occurs—whether from lightning, utility grid fluctuations, or other sources—the surge protector detects the excess voltage and diverts it away from your home's electrical system. It essentially absorbs or redirects the surge, preventing it from damaging your devices and appliances.

4. Service Entrance Rating:

The term "service entrance rated" indicates that the surge protector is capable of handling high-voltage surges that originate from the main power line entering your home. This rating ensures that the surge protector can effectively manage even the most severe spikes in voltage.

5. Professional Installation:

Installing a service entrance rated whole home surge protector requires a licensed electrician due to its placement at the main electrical panel. It's important to ensure proper installation to maximize its effectiveness and ensure safety.
