Whole-Home Surge Protection: An Important Upgrade Contractors Should Be Offering

One moment, a family is enjoying a quiet evening at home. One child is deep into an online game in the media room, another is glued to the latest binge-worthy series, and mom is putting the finishing touches on her online store’s big sale.

Without warning, the lights flicker, and a loud crack of thunder rattles the home. In the blink of an eye, a powerful surge is sent throughout the home’s electrical systems. Screens go dark, the Wi-Fi router dies and the gaming console won’t restart.

The kids are screeching in agony and drama, mom is upset and now several of their electronics are nothing more than paperweights. Dad has a sinking feeling as he realizes how expensive this could soon get. Replacing gaming systems, EV charging units, televisions, networking gear and computers quickly adds up to thousands of dollars.

Even more frustrating is that much of this damage could have been avoided with a simple surge protection strategy designed to protect their electronics.

Gone are the days when plugging electronics into a basic surge strip was enough. Today’s homes are filled with electronics, smart devices and systems that require comprehensive surge protection. The demand for essential surge protection for modern technology is simply not an option anymore.

As safety standards evolve, contractors are in a unique position to help customers manage their energy usage, improve safety and take control of their systems with Leviton solutions.

Power Surges Cause Immediate and Hazardous Damage

Power surges occur for a variety of reasons, including lightning, transformer malfunctions, power grid switches by the electric utility company, and the turning on and off of high-powered electrical appliances such as refrigerators or air conditioners.

An electrical boost above 169 volts creates an electrical current arc, generates heat and damages the electronic circuit board and other components. Additionally, small daily surges wear on electrical equipment and reduce their lifespan.

Modern homes contain more electrical components than they did just a few short years ago. Smart home revenue is projected to reach $193.5 billion dollars in 2026, and this trend won’t be slowing for the foreseeable future. The market is expected to have a compound annual growth rate (CAGR) of 23.1% through 2032.

 

National Electrical Code Changing with the Times

The National Electrical Code (NEC)is changing to accommodate these rising demands. NEC Article 230.67 Surge Protection was introduced in the 2020 code, requiring that all services supplying dwelling units be provided with a Type 1or Type 2 surge protection device (SPD) as an integral part of the equipment or installed immediately adjacent. In 2023, the NEC expanded the requirement list to include dormitory units, nursing homes, guest rooms at hotels and patient sleeping rooms.

The most recent 2026 NEC update shows just how important elevated surge protection is and includes fire stations, police stations, ambulance and rescue stations, ranger stations and similar facilities with overnight occupancy.

Leviton, Your Trusted SPD Brand for Decades

Leviton has been a trusted surge protection brand in homes for decades. By expanding and building Type 1, 2, and 3 SPDs, Leviton provides a comprehensive and complete approach to home protection, incorporating the latest in surge technology.

Leviton offers the Type 1, Type 2, and Type 3 surge protection devices your customers need to keep their homes safe and connected.

  • Type 1 surge protectors can be installed before the service equipment overcurrent device and protect against external surges when mounted at this location. Type 1 devices can also be used in Type 2 applications.
  • Type 2 surge protectors must be mounted on the load side of the service equipment overcurrent device. These devices protect against externally and internally generated surges, such as those driven by motor loads.
  • Type 3 surge protectors are used at the protected equipment, such as TVs, gaming systems, and computers, shielding them from surge transients and serving as the last line of defense.

With the MyLeviton app, monitoring homeowner energy usage is so easy. When you install the Leviton Whole Home Energy Monitor (LWHEM) in any Leviton Load Center, you give homeowners a way to view their energy usage in real time and remotely control the units. Giving them peace of mind and improving efficiency.

Surge Protective Breakers: For use in the Leviton Load Center, these Type 1 in-panel breakers feature an easy-to-read LED indicator light showing power and protection status and stay lit even if the breaker is off or tripped.

Surge Protective Panels: Leviton offers R, P, B, M Series Panels and X Series Panels. Leviton’s SPD panels are NEC-compliant, and contractors can choose the best panel for the needed application.

Tony Pulsonetti, Leviton’s Sr. Director of Strategy and Planning and Product Management for C&I, said, “The panels meet key NEC and UL requirements, including a 200kA SCCR rating and the NEC‑required nominal discharge current for dwelling units.”

For use with TVs, computers, and other expensive electronics, Leviton’s Type 3 surge protected receptacles are ideal for point-of-use surge protection. With several models, an audible alarm sounds when the surge outlet needs to be replaced, and all have an LED indicator that will extinguish when surge protection is lost, giving added confidence.
