What to Look for When Buying Whole House Surge Protectors
Whenever I purchase a surge protection device, the first thing I consider is its brand. Although I’m open to testing other models, I already prefer some specific brands, as long as I get positive feedback from my clients and colleagues.
However, for most people, these are the critical specifications to look out for: load capacity, surge capacity, breaker box compatibility, protection modes, and warranty.
- Load capacity – the surge protector you choose must support the current your system is using. If you have a 50-amp system, you cannot use a surge protector rated only for 30-amps.
- Surge capacity – different models have different capabilities. If you live in an area prone to lightning strikes, I recommend getting whole home surge protectors with the highest possible surge protection rating, but for other applications, you could settle for entry or mid-level models.
- Breaker box compatibility – as mentioned above, some protectors only work with specific load center models. Be aware of this before making your purchase to ensure compatibility.
- Protection mode – if you have a small system, the basic two modes of protection should suffice. However, if you have a larger or more complicated circuit, a more advanced surge protector might be required. It’s best if you consult a licensed electrician if you’re unsure.
- Warranty – I prefer models with warranties and guarantees as they make me confident that the company stands behind its product.
What are the Different Types of Whole House Surge Protectors
There are three primary types of power surge protectors: type 1, type 2, and type 3. These types refer to their placement in your system.
- Type 1: Service Entrance Home Surge Protectors – these are generally the most formidable surge protectors you can buy. They are the primary defense line for your home against electrical surges. They are installed between the utility pole or meter and the main breaker of your system.
- Type 2: Whole House Surge Protector Devices – these types of protectors are typically installed inside your main breaker. These typically protect the entire home circuit, hence the term “whole house”.
- Type 3: Receptacle Surge Protector – this is the smallest and most affordable surge protector. It’s most commonly found in power strips, which allow you to protect your devices while allowing them to share a single receptacle.
Although these power strips are effective against low-level surges, they will simply be overwhelmed by a significant jump in current or voltage. Nevertheless, I still recommend a surge strip for sensitive electronics.
Who Makes the Best Whole House Surge Protector
Any of the brands I’ve listed in the reviews should provide sufficient surge protection to your home. Another manufacturer worth checking out is Tripp Lite. Its 12-outlet model excels in protecting your gadgets and comes with an automatic power-off feature.
Do Whole House Surge Protectors Really Work
Yes, they do work! I have seen several instances where I was referred to work on my client’s neighbor’s electrical circuit after they lost several pieces of equipment due to a power surge. On the other hand, my clients just had to replace their surge protective device to maintain the circuit’s security.
These are the pros and cons of whole house surge protector. One positive about it is that it will prevent surge damage to your electrical equipment and help you save thousands of dollars. It can probably even reduce your insurance premium, as it protects all your plugged devices. Even if you don’t suffer from an extreme surge charge, low-level voltage spikes can damage sensitive circuit boards.
One negative I could think about is that it will cost you some money. It’s not much, but it’s still an expense. However, I prefer to think of it as an investment. After all, what is the cost of this device compared to the rest of my electrical equipment?
How Often Should a Whole Home Surge Protector be Replaced
In a perfect world, if you don’t suffer from electrical surges and power fluctuations, the best whole house surge protector devices will never need to be replaced. However, that is not the case. As most professionals agree, it’s best to replace this equipment every two years. Similarly, consumer reports indicate the same average effective life span for these items.
You should also occasionally check the status LEDs of your devices so you can visually inspect them. One rule of thumb we go by is that if you cannot remember when you purchased your protector, it’s high time you considered replacing it.
A surge protector is an investment. It will be the device that will take all the damage should your electrical circuit suffer from a massive power surge. Although it might be a bit expensive at the start, just think about what it will cost you if all your electrical devices, like your appliances, computers, smartphones, and everything else plugged in an outlet, get damaged or destroyed.
The bottom line is you should invest in the best whole house surge protector. This can potentially save you hundreds, if not thousands of dollars. It could also keep your electrical system and house from getting damaged. If you’re unsure whether you should get one or not, the best thing you could do is consult a professional.
