If you recently spent a tidy sum on a new appliance or a piece of electronic equipment, you may be wary of putting out extra money to purchase a surge protector. However, when you consider the fact that just one power surge or even a spike has the potential to damage expensive equipment, which may result in spending even more to replace it, the $20.00 to $50.00 it will cost to protect your investment is quite a bargain.
Surge protectors look like a strip or a box, covered with electrical receptacles (outlets). Power flows through the surge protector rather than directly to your equipment, so the unit can absorb power surges and spikes, protecting your appliances and electronics.
Power surges and spikes occur when there is a brief increase in voltage. How brief? Mere fractions of a second, and while surges are the most dangerous, spikes are potentially dangerous as well. This is especially true if they are recurring.
Even if your equipment is not destroyed, severe damage can occur. It may not even be noticeable at first, but continued exposure to spikes and surges will have a harmful effect on your equipment.
There are several different causes for spikes and surges, and lightning strikes can be a factor. It is best to turn off sensitive equipment during storms, even if you have installed surge protectors.
When shopping for surge protectors, there are certain features you need to look for:
-Quality units bear the ¡°UL¡± symbol. This symbol stands for Underwriter¡¯s Laboratories, which is non-profit, independent organization that has been testing and certifying products for over one hundred years, to insure that they meet industry standards for safety.
-Look for a good warranty. A reliable manufacturer should guarantee your equipment if the unit is properly installed but your equipment is still somehow damaged or destroyed.
-For computers, make sure the surge protector also protects the phone line.
-Check the clamping voltage. This is the level at which a surge protector will redirect the power. Choose a surge protector with the lowest possible clamping voltage, under 500.
-Examine the joules rating. This rating specifies how much power the surge protector can absorb. Unlike clamping voltage, where the lowest number offers the best protection, the joules rating should be high. Choose a unit with 500 joules or more.
Installing a surge protector is something anyone can do. Just plug the unit into an electrical outlet, plug your equipment into the receptacles on the unit, and turn the unit on.
Having a surge protector also makes it much easier to turn off your equipment in case of a sudden storm. Rather than running around turning things off or unplugging each item, just unplug the surge protector.
Using a surge protector for any item that contains a microchip is the safest bet. Of course, if you have a ¡°smart¡± toaster that only cost $25.00, you are not likely to purchase a surge protector that costs as much as the appliance. However, if you own top of the line appliances and electronics that cost hundreds or even thousands of dollars, spending a small fraction of that amount to protect them is an affordable precaution that makes good sense.
