Do whole house surge protectors really work?
Do Whole House Surge Protectors Really Work? Yes! A whole-house suppressor instantly blocks the surge from entering home circuits to provide comprehensive lightning protection. Individual plug-in suppressors can’t protect electronics that aren’t plugged in, but are hard-wired instead.
How are whole house surge protectors installed?
Step 1: Shut Off the Power. Open the door on your home’s main electrical service panel and turn off the main breaker switch located at the top of the panel. Step 2: Prep the Panel. Step 3: Mount the Surge Protector. Step 4: Connect the Wires. Step 5: Reassemble the Electrical Panel and Test.
Does whole house surge protector need dedicated breaker?
Surge protectors do not have circuit breakers. They have a connection to the ground wire. When they encounter a surge, surge protectors divert the excess current to the ground. This allows them to send the excess electricity to the ground.
Where does a whole house surge protector go?
A whole house surge protector that is installed at your circuit breaker panel within the house. It is wired directly into a dual-pole breaker, which is in your main breaker. And in some cases can be routed through your sub-panel for down-streaming.
How often should a whole house surge protector be replaced?
Surge protectors that regularly absorb power surges wear out faster than those in homes with fewer surges. Many devices have warranties of five years or more, but electricians generally recommend replacing surge protectors every two years.
What size whole house surge protector do I need?
The recommended minimum protection from a whole-house system is 40,000 amps, though many are much higher. A lightning strike is usually around 30,000 amps. That said, it’s always advisable to unplug what you can if a lightning storm is imminent.
Are some surge protectors better than others?
A higher joule rating is the best indicator of greater protection. Choose a surge protector with a joule rating at the very least in the 200 to 400 range. Sensitive or costly equipment, such as computers, displays and audio/video equipment, warrants a joule rating of at least 1000.
Are whole house surge protectors required by code?
Since the 2020 code has yet to be adopted by any government entity, the recommendation for whole-house surge protection is currently not required under law. The decision to install whole-house surge protection is advisory, Sargent says.
Do refrigerators need surge protectors?

What size breaker do I need for surge protector?
Essentially, the circuit breaker must be sized to the protector’s wire size and the electrical panel’s ratings. For example, a surge protector with 10 AWG wires should be used with a breaker rated at 30A. The circuit breaker’s ratings (interrupt rating, voltage rating) must also be suitable for the panel.
What happens when a whole house surge protector trips?
These minor power surges may not cause a noticeable response, such as tripping circuit breakers. Over time, however, they cause problems with your appliances and electronics, degrading their performance and potentially frying the circuit boards of everything from your electric stove or computer to even LED light bulbs.
How much power does a whole house surge protector use?
Whole-house systems should be rated to stop a 40,000-amp surge, at minimum. Features to look for include thermal fuses, and lights or alarms that indicate when a device has taken a hit. Protection for an average house with 200-amp service will run about $500—including a couple of hours of an electrician’s labor.
