A surge protector is a defense against unpredictable spikes in electrical current that can severely damage your home’s electric systems and your devices.

But what does a whole house surge protector cost to safeguard your home with one of these devices? Let’s dive in and find out.

Understanding Surge Protectors

What Is a Surge Protector?

Essentially a surge protector is a device designed to protect electronic devices from voltage spikes. It attempts to limit the voltage supplied to an electric device by either blocking or shorting to ground any unwanted voltages beyond the safety threshold.

How Do Surge Protectors Work?

Surge protectors use components like metal oxide varistors (MOVs) to absorb excess voltage, ensuring that only the necessary amount of power reaches your devices. This is crucial for preventing damage and extending the life of your electronics.

Common Sources of Power Surges

Power surges can come from various sources, including lightning strikes, power outages, and even the operation of high-power electrical devices. Understanding these sources is the first step in recognizing the importance of surge protection.

The Impact of Power Surges on Home Appliances

Without protection, power surges can significantly damage or even destroy home appliances and electronics, leading to costly replacements and repairs.

Types of Whole House Surge Protectors

These are installed at your home’s breaker box and provide protection from surges originating inside your home.

Combination Surge Protectors

Offering the benefits of both Type 1 and Type 2, combination surge protectors provide comprehensive protection against internal and external power surges. These surge protectors provide protection from both internal and external sources of power.

Russell did a great job getting my older home generator going. It seemed a simple fix - a tune up, but the other electrician who's serviced it multiple times didn't do a routine tune up. Now she runs strong when the weekly cycle starts, and she can hold the full load. 3 Phase has done other jobs too, but the generator was the one thing stressing me.out. I highly recommend 3 Phase.
