FAQs

How do I choose a whole house surge protector?

When choosing a whole-house surge protector, the minimum rating is usually 10kA (10,000 amps). However, it is important to note that the rating depends on the type of device. The best whole-house surge protectors are usually rated from 30kA and up. This is generally sufficient to deal with the worst storms or power generation problems. However, if you live in an area with particularly severe weather conditions, you may want to consider a surge protector with an even higher rating.

Is it worth getting a whole house surge protector?

Whole house surge protectors are definitely worth the investment if you want to ensure that your entire home is protected from power surges. While power strip surge protectors can help during frequent small surges, they are not nearly as effective during a high-surge situation. Whole house surge protectors will help to reduce both the frequency and severity of power surges, keeping your home and your appliances safe.

How long does a whole house surge protector last?

You can expect a whole house surge protector to last between 2 and 5 years. Because a surge protector's functional lifespan is measured by the cumulative total of the number and size of the surges it absorbs, not years, any lifespan estimate is going to be somewhat rough. 

But in general, you can expect a good quality whole house surge protector to last for a few years before it needs to be replaced. This is why it's important to choose a surge protector with a good warranty - so you can get it replaced if it does go bad within a few years.

Are expensive surge protectors worth it?

Yes, expensive surge protectors are definitely worth it! They offer much better protection against power surges than cheap surge protectors, so if you want to be safe from damage caused by lightning or power fluctuations, it's definitely worth spending the extra money on a high-quality surge protector.
