The Top 8 Best Whole House Surge Protectors [2021]

Last updated on January 8, 2021

This is something you can’t afford to save on. You need a good whole house surge protector to protect your entire system of electronics from power surges. Here are the best options for 2021.

Our top choice: Siemens FS140

A whole house surge protector is one of those things that you don’t give a second thought about when it’s doing it’s job. But if it’s not present (or if it’s broken) you’ll notice it when the worst happens (a big power surge burns your electronics worth thousands). So paying a few hundred to get and install a protector is very much worth it because surges do happen more often than you think.

What do you need to know when choosing a power suppressor (another way to call it) device?

  • It has to meet the UL Standard 1449 (it has to be accredited) – all of our picks for this list do.
  • You need a powerful device but you don’t have to overpay for it. The recommended surge current protection rating is at least 20,000 amps (20kA). Other specifications to look for: voltage clamping (400V or less), energy absorption (600J or more), protecting all lines, having a circuit breaker.
  • You never actually notice when a surge protector works (or when a surge happens, especially if it’s small) so LED indicators are a simple but a must-have feature to let you know about the status.

Of course, they don’t come with just the features, there are also some issues you might encounter. Knowing them is half the battle.

Some common issues you need to be aware of:

  • Quality of the build – you don’t want to waste your money and time on something that won’t do the job properly.
  • How to install – if you’re not an electrician you need to hire one to install these, and the more time they need to install it the more money you spend.
  • Compatibility so that you won’t waste time buying something that won’t fit into your power panel.

Finally, please be aware that even the most powerful surge protector won’t protect your electronics from the surges that happen inside your home power circuit. These are usually caused by power-hungry devices like a microwave, an AC, a heater, and so on. So be sure you use power strips to plug in your computers, home theater, and other sensitive devices (and never to the same strip as the big appliances.)
