Surge Protection Installation

What do surge protectors do?

A surge protection device is like a superhero for your electronics! It helps protect your computer, TV, and other things that use electricity from something called a power surge.

A power surge happens when there is too much electricity going through the wires in your house all at once. This can happen if there is a big storm nearby or if a big machine turns on or off somewhere close by. When this happens, it can make your electronics not work well or even break them.

A surge protection device is like a shield that catches the extra electricity and sends it to the ground instead of letting it go to your electronics. Think of it like a big bucket that catches the extra water when it rains, so it doesn't flood your house.

There are different types of surge protection devices. Some you can plug into an outlet, like a lamp, and it will protect the things you plug into it. Others are installed in your whole house and can protect everything from power surges.

In summary, surge protection devices are a superhero for your electronics, they catch and redirect extra electricity that can damage your devices and appliances during a power surge.
