Whole House Surge Protector Buyer's Guide
Written by Jim WilliamsIntroduction
A whole house surge protector is a device that is installed in the main service panel of your home. It is designed to protect all the electronic devices in your home from power surges. A power surge is a sudden spike in voltage that can cause permanent damage to your electronic equipment. A whole house surge protector can help protect your electronics and appliances from damage caused by power surges. It is important to understand the different types of whole house surge protectors and the features they offer in order to make an informed decision when purchasing one.
Types of Whole House Surge Protectors
There are two main types of whole house surge protectors: point-of-use surge protectors and whole house surge protectors. Point-of-use surge protectors are designed to be installed directly at the outlet and can provide protection for any device plugged into the outlet. Whole house surge protectors are designed to be installed in the main service panel of your home and are designed to provide protection for the entire home.
Main Features
The main features to look for when purchasing a whole house surge protector include protection rating, response time, and joule rating. The protection rating is the highest voltage your surge protector can handle before it shuts off power to your home. The response time is how quickly the surge protector will respond to a power surge. The joule rating is the amount of energy that the surge protector can absorb before it shuts off power to your home.
Surge Protection Rating
The surge protection rating is measured in volts and indicates how much voltage your surge protector can handle before it shuts off power to your home. The higher the number, the better the protection. Most surge protectors are rated for 120 volts, but some higher-end models may be rated for up to 240 volts.
Response Time
The response time is how quickly the surge protector will respond to a power surge. The faster the response time, the better the protection. Look for surge protectors with a response time of 10 nanoseconds or less.
Joule Rating
The joule rating is the amount of energy that the surge protector can absorb before it shuts off power to your home. The higher the joule rating, the more energy the surge protector can absorb before it shuts off power. Look for surge protectors with a joule rating of at least 1000 joules.
