Whole-House Surge Protection in Louisville & Lexington
Having your home’s electricity go out during a power surge may not seem like a big deal. Still, this common household headache can damage the performance and quality of your electronics. If this happens to you, it’s important to address it quickly to protect your home from future surges.
Fortunately, Dauenhauer offers whole-house surge protection for residents in Louisville and Lexington. Our skilled technicians have the certification and experience to protect your home and electronics.
What is a Whole-Home Surge Protector?
When a power surge happens, extra electricity is pushed from power outlets to electronic devices, causing them to overheat, burn, or malfunction. A whole-home surge protector prevents this by redirecting extra electrical power away from external devices.
As you know, electronics can be expensive. Surge protectors help protect your investments and keep your household safe. Dauenhauer’s professional electricians install whole-home surge protectors at your home’s main electrical panel, offering comprehensive coverage of your entire electrical system.
Why Surge Protection is Important for Kentucky Homes
Kentucky is no stranger to severe lightning and thunderstorms, and most homeowners’ insurance policies do not cover damage to electronic devices. Additionally, replacing damaged power outlets and electricity sources can be quite expensive.
Installing one of Dauenhauer’s surge protectors or whole-house generators is a great way to ensure your home is always powered and protected from unexpected power surges.
By installing surge protectors and whole-house generators, you can expect that:
- You will have restored power quickly
- You can keep your devices running (personal, medical)
- You are protected against power surges post-outage
- You stay safe during an emergency

Power surges are unpredictable, and when they happen, nothing can prevent damage to your electronic devices besides a surge protector.
Installing a whole-house surge protector and conducting regular electrical maintenance can save you time and money when it comes to keeping your home and electronics safe.
Types of Damage Surge Protectors Help Prevent—and Don’t Prevent
Surge protectors are designed to protect your electronic devices from damage caused by power surges and voltage spikes. However, it is also essential to know what they don’t protect.
Here’s a list of what surge protectors can’t do.
- Surge protectors cannot stop power outages. Whether caused by natural events or human error, power outages happen regardless of whether you have a surge protector.
- Surge protectors cannot prevent a lightning strike. Lightning strikes happen at the hands of Mother Nature—something that a surge protector cannot and will not prevent.
- Surge protectors cannot counteract voltage drops. Voltage drops indicate potential issues in your electrical system; surge protectors cannot fix this.
- Surge protectors cannot shield your devices from physical damage or wear and tear. They are designed to defend against electrical spikes, not drops, spills, or long-term component degradation.
- Surge protectors cannot protect data cables; they only protect power cords. To safeguard Ethernet, coaxial, or phone lines, you’ll need a surge protector specifically designed for those types of connections.
- Surge protectors cannot stop electrical damage due to bad wiring. Faulty or outdated wiring can cause consistent voltage irregularities that bypass standard surge protection.

Surge Protection FAQs
Is a whole-home surge protector now required by code?
Yes, for new or replacement residential service equipment. NEC 2020 Article 230.67 requires that all services supplying dwelling units be provided with a Type 1 or Type 2 surge protective device (SPD), either integral to the service equipment or located immediately adjacent, and this requirement carries through the 2023 NEC. The rule also applies when existing service equipment is replaced (a panel upgrade triggers it). Jurisdictions enforce this on final electrical inspection.
What’s the difference between a Type 1 and Type 2 surge protector?
Type 1 SPDs are installed on the line (utility) side of the main breaker — directly between the meter and the main disconnect — and catch surges before they ever enter the panel. They’re rated to do so without an external overcurrent device. Type 2 SPDs are installed on the load side of the main breaker, typically bolted into a dedicated two-pole slot in the main panel, and protect everything downstream. For most homes a Type 2 at the main panel is the standard spec; in lightning-heavy areas or homes with expensive equipment (servers, medical), adding a Type 1 at the meter gives a two-stage cascade.
Do I still need power strips at the outlet if I have a whole-home SPD?
Yes — a whole-home (Type 2) SPD is stage-one protection. It clamps the big hits (lightning-induced transients, grid switching spikes) but allows a residual voltage through, typically under 600V let-through. Sensitive electronics (PCs, AV gear, smart-home hubs, medical equipment) benefit from a second-stage point-of-use surge protector on a quality power strip. The two-stage “cascade” is what manufacturers (APC, Tripp Lite, Eaton) recommend for full protection.
Does a surge protector protect against lightning?
A direct lightning strike on the service drop is unsurvivable — no residential SPD is rated for that. What SPDs are built for is the far more common indirect/induced surge: a strike on a nearby line that sends a transient voltage down the utility feed, or a utility-side switching event. ESFI, NFPA and Ditek data show that over 80% of damaging residential surges originate inside the home (motor loads cycling on and off), not from lightning — which is why code now requires a SPD on every new panel.
