Modern homes rely on more electronics than ever…smart TVs, computers, gaming systems, smart home devices, and sensitive HVAC equipment. With all these devices plugged in, protecting your home from electrical power surges is more important than ever. While power strips and whole house surge protectors both offer protection, they work very differently and provide very different levels of protection against power surges.
The licensed electricians at Central Heating Cooling Plumbing Electrical created this guide to help you understand the difference, so you can choose the right level of protection for your Kalispell home.
What Is a Power Strip?
A power strip is a small device with multiple outlets that makes it easy to plug in more devices at a single location. Some power strips include light surge protection, but many are simply extension outlets with no built-in safety features.
They’re commonly used for entertainment centers, home offices, and small electronics, but their protection is limited.
Pros of Power Strips
- Affordable and easy to find
- Simple to install, just plug into an outlet
- Portable and can move room to room
Cons of Power Strips
- Limited surge protection, most can’t handle large or repeated surges
- Only protects the devices plugged into it, not your whole home
- Short lifespan, the internal surge protector degrades over time
- Can cause clutter or even overloaded outlets when misused
What Is a Whole House Surge Protector?
A whole house surge protector (also called a surge protective device or SPD) is installed at your main electrical service panel. Instead of protecting only one outlet, it protects your entire home’s electrical system, including large appliances and sensitive equipment.
This level of protection is especially important in areas like Montana, where weather, fallen power lines, and grid fluctuations can cause large, unexpected surges.
Whole-home surge protectors help defend:
- Furnaces, boilers, and HVAC systems
- Refrigerators, freezers, washers, and dryers
- Computers, Wi-Fi routers, and home office equipment
- TVs, smart home devices, and charging stations
- Dishwashers, microwaves, and kitchen appliances
Pros of Whole House Surge Protectors
- Comprehensive protection for everything in your home
- Designed to handle large surges from lightning or grid issues
- Long service life and more reliable than power strips
- Reduces fire risk caused by overloaded or damaged equipment
Cons of Whole House Surge Protectors
- Higher initial cost for device and installation
- Professional installation required—this is not a DIY project and must be installed by a licensed electrician.
Why Upgrade to Whole House Surge Protection?
While power strips offer convenience, they don’t provide true whole-home defense. A single powerful surge can destroy thousands of dollars’ worth of electronics in seconds.
Upgrading to a whole-home surge protector offers:
Protection from Large Surges
Powerful surges from lightning, storms, or utility issues are diverted before they reach your appliances and electronics.
Long-Term Savings
Instead of replacing damaged HVAC systems, kitchen appliances, computers, or TVs, a surge protector absorbs the hit and helps prevent costly repairs or replacements.
Enhanced Home Safety
By preventing overheating and electrical damage, whole-home surge protectors lower the risk of electrical fires and help protect your home and family.
Are Whole Home Surge Protectors Required in Montana?
Yes, whole-home surge protectors are required in all new residential units in Montana built after 2020. The National Electric Code (NEC) mandates that a surge protection device (SPD) be installed in new construction, remodels, and upgrades to existing electrical services.
The surge protection device can be either a Type 1 or Type 2 and can be integrated into the electrical panel or located right next to it. In all cases, installation should be performed by a licensed electrician to ensure safety and code compliance.
Do You Still Need Power Strips if You Have Whole House Protection?
In most homes, the answer is yes. Whole-home surge protectors stop major surges, but smaller everyday fluctuations can still occur inside your home’s wiring.
Using quality surge-protecting power strips for sensitive electronics—such as TVs, computers, and gaming systems—adds a helpful second layer of defense. Think of whole-home surge protection as your first line of defense, and point-of-use surge strips as backup protection at the outlet.
