Whole-Home Surge Protection
Protect every circuit, outlet, and appliance in your home from power surges with professional whole-home surge protection installed by Kochs Electric. Our comprehensive surge protection services are designed for homeowners who want reliable house surge protection across their homes and properties.
5 Highlights on Whole-Home Surge Protection
- Full-service coverage at the main panel. Whole-home surge protection installs directly at your service entrance, so every branch circuit, sub-panel, and downstream outlet gets shielded from transient voltage spikes before they reach your devices.
- MOV-based suppression technology. Metal-oxide varistors clamp overvoltage events in nanoseconds, diverting excess current away from conductors and receptacles throughout your home.
- NEC-compliant, UL-listed devices. Every SPD (surge protective device) Kochs Electric installs meets ANSI, IEEE, and NEMA standards, and our work is permitted, coded, and inspected.
- Joule-rated capacity you can count on. We size each whole-home TVSS unit to match your service amperage, whether you run a 100-amp or 400-amp single-phase residential system.
- Indicator light and alarm monitoring. Installed units include status indicators so you know your surge protection is active, absorbing, and functioning after every electrical event.

Signs You Need Whole-Home Surge Protection
Your appliances or electronics fail earlier than expected: Repeated exposure to small transient voltage spikes degrades motors, compressors, and circuit boards over time. If your HVAC system, refrigerator, or washer is failing ahead of its rated lifespan, cumulative overvoltage events from the utility feed may be the cause. Common power surges are also caused by appliances cycling on and off, creating sudden swings in electrical demand that accelerate wear and lead to costly replacements. Whole-home surge protection suppresses those transients before they reach your equipment.
You’ve had a lightning strike nearby: A nearby lightning event can send a massive voltage spike through your service entrance and into every connected circuit. If you’ve experienced flickering lights, tripped breakers, or dead outlets after a storm, your wiring and devices absorbed that energy. Installing a whole-home SPD at the main panel protects against future lightning strikes and shields your entire electrical system from destructive surges.
Your home has older wiring or an aging panel: Older residential panels and ungrounded or uninsulated conductors are more vulnerable to transient interference and harmonic noise from the utility grid. Kochs Electric can inspect your panel, diagnose any existing fault conditions, and install a surge protective device rated for your service. Our electrical inspections help identify vulnerabilities before they become expensive problems – protecting your valuable assets and keeping your electrical services running reliably.
You run sensitive electronics or home office equipment: Computers, smart home systems, and medical devices are especially vulnerable to EMF interference and voltage spikes. Smart devices and valuable electronics face constant electrical stress from unregulated power – and repeated surges can eventually trigger electrical fires or total device failure. Point-of-use surge strips don’t provide the upstream protection that a whole-service SPD delivers at the meter or main panel.
Your utility provider has frequent switching transients: Utility grid switching, power restoration after outages, and load changes on the distribution network generate transient spikes that travel downstream into your home. If your lights flicker regularly without an internal cause, your service entrance is absorbing those events. A whole-home surge protector installed at the service entrance stops them at the source – ensuring clean electricity throughout your home and maintaining electrical safety for your family.
Our Whole-Home Surge Protection Process
Step 1 — Assessment and evaluation. We inspect your main panel, sub-panel configuration, service entrance, and grounding system. We check amperage, identify your single-phase or three-phase setup, and confirm your grounding and bonding are code-compliant before we install anything.
Step 2 — Device selection. We select a UL-listed, NEC-compliant SPD with the correct joule capacity, clamping voltage, and let-through voltage rating for your service. We match the device to your panel’s breaker configuration and available mounting space.
Step 3 — Safe de-energization. We disconnect and de-energize the appropriate circuits at the main breaker or service disconnect. We follow all safety protocols before we open the panel enclosure or touch any hot conductors.
Step 4 — Installation and connection. We mount the SPD in or adjacent to the main panel, connect the hot, neutral, and ground conductors, torque all terminals to manufacturer spec, and verify proper bonding to the grounding system.
Step 5 — Testing and inspection. We re-energize the service, test the SPD’s indicator light and status function, verify no fault conditions exist, and walk you through what the device does and how to monitor it. We document the installation for permit and inspection purposes. Thorough electrical inspections help ensure every component of your surge protection solutions is working correctly before we consider the job complete.

FAQs About Whole-Home Surge Protection
What is whole-home surge protection?
Whole-home surge protection is a surge protective device (SPD) installed at your main electrical panel or service entrance. It clamps transient voltage spikes and diverts excess current before it travels downstream to your circuits, outlets, and connected appliances – protecting the flow of clean electricity throughout your home.
How does whole-home surge protection work?
The SPD uses metal-oxide varistors (MOVs) to detect overvoltage events. When voltage exceeds the device’s clamping threshold, the MOVs absorb and divert the excess energy to the grounding system in nanoseconds, protecting everything connected to your panel.
When should I install a whole-home surge protector?
Install one now, before a surge event occurs. Transient spikes from lightning, utility switching, and large motor loads happen without warning. Waiting until after damage occurs means replacing appliances, electronics, and wiring that a properly rated SPD would have protected. If you have questions about your surge protection needs, contact Kochs Electric to schedule an appointment.
Why isn’t a power strip surge protector enough?
Point-of-use surge strips only protect devices plugged directly into them. They don’t protect hardwired appliances like your HVAC system, water heater, or refrigerator. A whole-home SPD at the service entrance protects every circuit in the building simultaneously.
Can Kochs Electric install surge protection on any panel?
Yes. We install whole-home surge protection on single-phase residential panels, sub-panels, and branch circuit configurations. We assess your existing panel before recommending a device to make sure the installation is safe, code-compliant, and correctly sized for your service amperage.
Does whole-home surge protection require a permit?
In most jurisdictions, yes. Kochs Electric pulls the required permits, completes the installation to NEC standards, and coordinates inspection so your surge protection is fully approved and documented.
How long does a whole-home surge protector last?
Most UL-listed whole-home SPDs are rated for years of continuous service, but their joule capacity depletes with each surge event they absorb. Kochs Electric can inspect and test your existing device, handle any necessary repairs, and replace it if its protection capacity has been exhausted.
