You might be wondering why we are making it out to be such a big issue. Let us start by having a better understanding of the threat you might be dealing with. Power surges or spikes are minor to major increases in the voltages in your electrical power lines. These can typically last only milliseconds, but their impacts are immensely considerable. The spikes in power can be one huge surge or multiple small surges. Every electrical appliance you have plugged in a power supply, may vulnerable to them. These include your refrigerator, oven, air conditioners, electric lighting, PCs, gaming consoles, or any gadgets plugged into your wall power outlets. Even though the majority of your devices are equipped with precautionary measures, they can, for the most part, only tackle small scale power surges.

This is where the surge protectors come into play. When installed, they not only allow the designated electricity levels to pass through but also actively monitor any increases in voltage. Any excess power is redirected to the ground wire, ensuring that your appliances only receive the allotted energy. They are therefore essential devices in protection against your appliances getting destroyed and costing hundreds to thousands of dollars to replace, or even worse!

At this point, now that you are familiar with what surge protectors or suppressors are and why they are crucial, there is one more detail that you have to consider: what type you need. Generally, you will come across 4. Type 1 surge protectors are installed outside of your premises and prevent your home from power spikes due to lightning strikes. Type 2, also known as service or branch surge panels protect you from all the internally generated surges in power.

These account for more than 80% of general power surges and are the most important of the bunch. Type 3 shares a lot of visual details with the power strips you use, as an extension of your wall outlet. Naturally, they offer protection to the devices only plugged into them and are generally inadequate against huge power surges. There is also a Type 4 category which is designed specifically for in an industrial application, to protect the commercial equipment. It is therefore completely unnecessary for domestic uses.

It is true, that in order to have a complete package, you should install all three (Type 1, 2 & 3) of the varieties of surge suppressors, but our opinion is to have or at least start with the Type 2. This is undoubtedly the most efficient and necessary one, as it offers the biggest range of protection. We have researched extensively into the online marketplace for the best possible whole house power surge protectors, prioritizing reliability, compatibility, convenience, lifespan, and most importantly, customer opinions.
