Frequently Asked Questions (FAQ) about Surge Protectors

Thursday, April 14, 2022

There’s about $15,000 worth of electrical equipment in the average home that can be ruined by a surge, according to the National Electrical Manufacturers Association. Compared to the cost and inconvenience of having to replace all the major appliances in your home, a few hundred dollars for a surge protector looks like a bargain. And now one is required by code in all new homes. 

Here’s links to answers for the most-often-asked questions we get about surge protectors:

• How do I find the right whole house surge protector? 

• Why is an undersized wire between a circuit breaker and whole-house surge protector acceptable?

• Can a home surge protector be installed loose in the bottom of an electrical box?

What is life expectancy of whole house surge protector? 

Does code require a whole-house surge protector for houses? 

• Can you plug a surge protector into a two prong outlet? 

• Does a whole-house surge protector need a dedicated circuit breaker?
