Questions and Answers:Surge and Spike Protectors
Q. |
I have lived here 15 years and I've never had any trouble with my appliances. Why do I need protection now?
|
|
Many older appliances were not sensitive to variances in power, but with the huge increase in the number of products that utilize microchips, the need to protect against surges and spikes is greater than ever. The typical devices that use microchips are televisions, VCRs, stereos, telephones, telephone answering machines, personal computers, sewing machines and microwave ovens. |
Q. |
Why can't EWEB protect me from sags, spikes and surges? |
A. |
The majority of sags, spikes and surges are triggered by an activity within your home, and sometimes, by your neighbor's use of machinery or equipment. Occasionally, you may experience a sag, spike or surge from weather-related events. |
Q. |
I have noticed that some surge and spike protectors have plug-ins for a telephone. What are these used for? |
A. |
Communication lines are attached to the same poles as power lines. When these two services come into contact, an electrical surge could result and travel down the telephone line. Surge and spike protectors will prevent the surge or spike from coming through the telephone line and damaging your equipment. Cordless phones, answering machines and personal computers with a modem seem to be especially sensitive. |
Q. |
Why should I buy a surge and spike protector for $50 or more when I can buy one for $10? |
A. |
Some surge protectors may not have adequate circuitry to protect your electronics from large or numerouse surges and spikes. Furthermore, the more expensive protectors come with a guarantee that covers any damage your equipment sustains when plugged into the protector. |
Purchasing a Surge Protector
When investing in a surge protector, look for these qualities:
- The surge protector should meet UL TVSS Standard 1449.
- It should allow for protection of communication lines (telephone and cable) in addition to your electric service.
- The surge protector should include a lifetime guarantee covering both the suppressor and your equipment.
- It should include an indicator light to clearly show that the device is functioning.
