FAQ:

Q: Do surge protectors really work?

A: Surge protectors only have a limited lifespan depending on how often they are put to work. Even when the surge protector properly diverts a surge so your electronics aren’t damaged, the protector itself can be damaged in the process. One of the most important features then is an indicator light.

Q: What to look for in a surge protector?

A: The three things to look for in a surge protector are: A big power rating. A good self test that lets you know it has died. It has both line to line and line to earth protection.

Q: Should I use a surge protector?

A: A surge protector is a set of electrical sockets that allow you to plug more than one appliance into a wall socket. It can be used by a range of appliances including computers and home entertainment systems. They provide a much safer alternative to adaptor plugs, protecting the user and the appliance from injury and damage.

Q: What is the difference between a surge suppressor and a surge protector?

A: Surge suppressor, as name suggests suppresses and regulates the voltage and makes the power constant in a case of a spike or surge. While a protector simply detects the surge and turns the unit off. Suppressor is good for things like computers, where you don’t want to keep turning on and off.
