Many offices have surge-protected sockets and extension cables for their computers, monitors and printers, but are they really needed? Well, let’s answer this by understanding how surge protectors actually work. They are designed to detect excess voltage and divert any extra electricity into the grounding wire. This is why all surge protectors will have a grounding pin (the third prong on a plug) and all surge protectors must be plugged into a properly grounded outlet for them to work as intended. So with that in mind, the answer would be yes they are very important. They essentially save your devices from obtaining too much voltage and if you care about your expensive equipment at all you’ll want to make sure you protect your items as best you can. Electrical surges happen, and the easiest way to stop them from damaging your electrical goods is to buy surge protectors.
