Science and technology have gifted many life-changing things to humanity in every sector of life. Ranging from better human colonization to equal and efficient health benefits and from fast-paced travel to almost everything, scientific and technological sectors played a crucial role in making life on Earth better. 

Why is Electricity Important?

Electricity is one of the finest examples of the application of science in the direction of a better humanity. Without it, our lives would be entirely incompatible and so much difficult in every way. Electricity has made a positive impact on our homes, in our foods, industrial sector, communication, transport, entertainment, education, and healthcare sector. 

This list is widely incomplete. Electricity is beneficial in so many ways that we can’t even count. 

For instance, in our home, we have so many appliances and devices that work with electricity. Refrigerators, lights, dishwashers, ovens, TVs all work with electricity. 

But, with so many benefits of these electric appliances in our home, there is a slight problem. Surges!

As you know, with every problem, there is a solution, just wanted to be found. 

We found this solution in Best Whole House Surge Protectors. 

Simply put, a whole house surge protector protects all the appliances in your home from voltage spikes, limiting excess electrical current by blocking its flow or shorting it to the ground, much like a pressure relief valve. 

Why do we need a whole house surge protector? 

Not everyone has one of it in their homes, but it is the best investment so far! Think of it as insurance for your expensive devices. 

Sudden surges are not your fault. It can be caused when excess lightning happens or what so ever reasons. You should stay protected at your end. 

Surge Protectors burn themselves but protect your whole house from surges. 

Think of it, Is it worth spending several thousand dollars to replace an expensive device, or are you better of spending between $100-$200 on a whole house surge protector? 

What to look in a best whole house surge protector? 

Professionals advise these factors to must-have in a surge protector.  

We always look up to these crucial characteristics of a whole house surge protector. 

  • Warranty: This one’s a lot easier to explain– the larger the warranty, the much better. Not just for the obvious factor that if something goes wrong, you’ll be able to make a claim, but for the signal that a long warranty suggests about the quality of the whole house surge protector. 
  • Voltage and Surge Protection Rating: Manufacturers of whole-house surge protectors often use terms like “high voltage protection.” A lightning strike can send 30,000 volts into a household electrical system, so protecting against that kind of power certainly sounds impressive. However, while the voltage protection rating is calculated by UL and CSA in their testing, they are often not prominent within the product details. Always check them up. 
  • UL Certification: UL, formerly known as Underwriters Laboratories, is an independent organization recognized worldwide for safety testing and certification. The current standard for surge-protection devices is UL 1449 (3rd Edition). The term “UL-listed” is frequently used. A whole-house surge protector is also listed and labeled as TVSS on devices. UL 1449 covers numerous aspects of the SPD, including how fast it reacts to a surge, the current required to trip it, and the level of protection offered. In order to pass, a whole-house surge protector must be able to produce results within the specified limits for as many as 15 consecutive tests.
  • Enclosure Type of NEMA: A NEMA enclosure is a rate of protection measured against environmental factors including dust, oils, water, coolant, and corrosive agents.It stands for The National Electrical Manufacturers Association. 
  • Nominal and Maximum Continuous Operating Voltage: The nominal voltage in the U.S. (the voltage provided at your household outlets) is 110/120 volts. In many other countries, it is 220/240 volts. Whole-house surge protectors are frequently capable of switching to either, but it is worth checking. The maximum continuous operating voltage (MCOV) is the amount of voltage the surge protector will allow through without tripping. This provides a margin of between 15 percent and 20 percent. For example, a 120-volt surge protector with a 20 percent margin would have an MCOV of 144 volts. 

Some General FAQ’s

 How often should a surge protector be replaced? 

Professional advice to replace your surge protector by every two years or so. The lifespan of a surge protector merely depends on the number of surges it bears every day. The metal oxide coating wears off with every spike. Yes, they can last longer but, the safest thing to do is to change your protector every two years.

Let us compare a whole-house surge protector with an ordinary power strip: 

The main contrast between a surge protector and a power strip is the ability to protect attached pieces of equipment. The first one uses a metallic coat to bear any excess power and can conduct electricity through it. A power strip only provides extra outlets to use. 

A surge protector can also act as a power strip, but a power strip cannot act as a surge protector.
