What Is Whole House Surge Protection?
Whole house surge protection guards your home’s electrical system from sudden voltage spikes. It works by controlling high voltage that could damage your appliances and electronics.
Understanding its purpose, how it functions, and the types available will help you decide if it’s right for your home.
Definition and Purpose
Whole house surge protection is a system installed at your main electrical panel. Its job is to block extra electrical power, called surges, before they reach your outlets and devices.
These surges often come from lightning strikes, utility switching, or problems with wiring. The purpose is to keep all your appliances safe at once, unlike regular surge protectors that only cover a few devices.
This protection helps prevent damage to your fridge, TV, HVAC system, and other important electronics. It also can save you money on repairs and replacements.
How Surge Protectors Work
Surge protectors sense when voltage spikes above safe levels. When this happens, they redirect or block the extra power, stopping it from passing through to your appliances.
They use components like metal oxide varistors (MOVs) to absorb or divert excess electricity. This prevents the power surge from damaging sensitive electronics.
Whole house surge protectors connect directly to your electrical panel. This position lets them protect everything in your home before electricity spreads to outlets.
Types of Whole House Surge Protection Devices
There are mainly two types of whole house surge protectors:
Type 1 Devices: Installed where power enters your home, usually outside or at the meter. They stop large surges from outside sources like lightning.
Type 2 Devices: Installed inside your electrical panel. They protect against smaller, internal surges caused by appliances turning on and off.
You can also combine both types for greater protection. Licensed electricians typically install these systems to ensure your home stays safe and code-compliant.
Why Appliances Need Whole House Surge Protection
Power surges happen quickly and can come from many sources. These surges can damage your home’s wiring and appliances, leading to costly repairs or replacements.
Protecting your whole home helps keep your devices safe and working longer.
Common Causes of Power Surges
Power surges can come from outside your home or inside it. Lightning strikes are a big cause of surges and can send dangerous voltage into your electrical system.
Utility grid issues, like sudden changes in power from your electric company, are another cause. Inside your home, large appliances like air conditioners, refrigerators, or washers can cause surges when they turn on or off.
These changes send extra voltage through your wiring that can harm other devices.
Risks to Home Appliances
When power surges happen, they push too much electricity through your appliances. This can cause parts of the device to burn out or stop working properly.
Over time, even small surges can shorten the life of your electronics and appliances. Without protection, your expensive devices like your TV, computer, or HVAC system are at risk.
Damage from surges can lead to expensive repairs or replacements you could avoid with proper protection.
