We all have many electronic devices in our homes, some of them more expensive than others. Since you invest quite a bit of money into purchasing them, you should make sure that they are protected in case of lightning striking your power grid, or a power surge occurring. A small investment you can make to ensure this is to buy a surge protector. Surge protectors are designed to redirect unsafe voltages back through to the ground.
Due to this, it is very important that your surge protector is connected to a properly grounded outlet, otherwise it will not function as intended.
It is important to note, too, that your surge protector will fail after it has dealt with a few surges, so if you experience them regularly, you will need to replace it quite often.
Often, your surge protector will come with a guarantee for electronics up to a certain value, but this is only valid if it is corrected properly.
