Surge Protection – do you need it?
Not very many people really understand surge suppression. Here’s some information that can help you answer important questions and find the solutions you need.
What is a surge?
A “surge” is a boost in electrical charge in a power line. This can be caused by lightning, but it is more commonly caused by high-power electrical devices such as air conditioners and refrigerators which require a lot of energy for starting and stopping compressors and motors. Some surges can also be caused by faulty wiring. Telephone and cable lines can also conduct high voltage and need surge suppression as well.
Why is surge suppression needed?
Electronic devices are much more delicate, sensitive and expensive than the older equipment ever was, which is why protecting them is very important.
How to select the right surge protection for you
All surge protectors are not the same. Pick a surge protector system that balances price with the cost of losing data or expensive electronic equipment. The general rule of thumb is that you get what you pay for, so look for a quality product. Here are a few important things to look for:
- Get a surge protector that states it is a "transient voltage surge suppressor" and meets criteria for UL 1449. (Some products look like a surge protector but are no more than extension cords.)
- Get a clamping voltage of 400V or less. The lower the better.
- Look for a joule rating of at least 200 to 400 minimum.
- Buy a surge protector with an indicator light that tells you the protection components are functioning.
- Better surge protectors come with a guarantee on performance backed by an insurance guarantee on your equipment.
Consolidated Electric offers a whole house surge protector that will protect the large appliances in your home (range, refrigerator, etc.). It is also a good idea to have individual surge protection on your computer, stereo, and other electronic equipment.
