Surge protectors aren’t just fancy power strips — they’re a key defense for your home’s most valuable electronics and appliances.
What causes power surges?
Surges can come from lightning strikes, utility switching, or even large appliances turning on and off. These quick spikes in voltage can seriously damage your TV, HVAC, fridge, and computers.
Plug-in vs. whole-home surge protectors
Plug-in models help protect single devices, like a desktop computer.
Whole-home systems are installed at your electrical panel and guard everything in your house at once.
Do you really need one?
If you have expensive electronics, work from home, or live in an area with frequent storms or grid changes — the answer is yes.
🛡️ Don’t wait for a costly burnout. Protect your home now.
Here’s what you should know about power surges:
• Surges happen more often than you think. They can be triggered by lightning strikes, utility grid switching, and even appliances like HVAC units cycling on and off.
• Power spikes can fry sensitive electronics. Think about your TV, gaming systems, computers, smart fridges — even your home automation gear. A strong enough surge can destroy them in an instant.
• Whole-home surge protectors stop the damage at the source. Installed at your main electrical panel, they protect everything plugged in throughout your house.
🛑 Still relying on power strips? That’s not enough. Those plug-in models don’t defend your full home or major systems like AC and heating.

Most homeowners think of power strips as surge protection — but those only guard what’s plugged into them. A whole house surge protector safeguards your entire electrical system from dangerous voltage spikes that can fry your appliances, HVAC systems, or even damage your home wiring.
Power surges can happen for many reasons:
Lightning strikes
Utility grid switching
Large appliances turning on and off
Transformer issues or tree damage
In places like North Reading, Peabody, and surrounding MA towns, older homes with outdated panels are especially vulnerable.
A whole house surge protector is typically hardwired into your main electrical panel by a licensed electrician. At CNE Electrical, our team:
Assesses your panel for compatibility
Installs a UL-listed surge protection device (SPD)
Verifies grounding and bonding systems
Pulls any necessary permits and handles inspection
Once installed, the SPD continuously deflects excess voltage away from your appliances and electronics, protecting your home 24/7.
Yes. Power strips only protect individual devices. A whole house surge protector covers your entire home, including hardwired appliances like refrigerators, HVAC systems, and washers/dryers.
Most surge protectors are rated for 5 to 10 years depending on brand and surge exposure. We’ll recommend models with indicator lights or alert systems to let you know when replacement is needed.
No system can stop a direct lightning strike, but whole house surge protectors help limit the damage from nearby strikes and electrical surges caused by lightning activity in your area.
