In recent years, surge protectors have become more important. The average American household has become more dependent on modern technology to maintain its standard of living. If you look around your home, you will notice that it is filled with new pieces of equipment that did not exist 5 or 10 years ago. All of this equipment brings with it a whole new set of problems that some of us never even thought of. What would happen if one day all of your appliances ceased to exist? I’m not talking about any far-fetched conspiracy: I am referring to the possibility that your home’s electrical system could be affected by a power surge. Los Angeles Electricians installs, repairs, and maintains surge protectors for your residential or commercial property.
Think about it: How much money is attached to your electrical system? How awful would it be if you did not have or needed to replace every piece of electrical equipment in your entire home? The average home gets hit with over 20 energy spikes per day. These spikes reduce the life of your appliances and electronics up to 30 percent.
If you owned one of the 30 million homes that got struck by lightening last year, you would understand how much you depend on your electrical devices throughout the day. A lightening strike could damage not only your computer and your television, but you could also lose your refrigerator, dishwasher and microwave. Your HVAC system runs on electricity, so it is also at risk. It only takes one summer storm to wipe out your air conditioning. The worst part is that many homeowners’ insurance policies do not cover lightening strikes. With the amount of money you would spend replacing all of that equipment, you could fly to a tropical island and spend a month drinking pina coladas!
What Do I Need to Know About Surge Protectors?
When you think about surge protectors, it should be addressed in two different ways, because all surges are not the same. Some start outside and work their way in. Others start from within the house itself. The two types of protection are whole-house surge protection and point-of-use surge protection.
Electrical surges coming from the outside of the home tend to be caused by things like lightening strikes and broken utility lines. These types of surges are less common than internal surges, but are more devastating to your home’s electrical system. Surges coming into your home from the main grid will not only destroy your sensitive electronics, but may also destroy all of your major appliances and damage the wiring in your walls as well.
Internal surges are generated from within the home. They make up about 70 percent of the power surges that a normal home confronts. They are usually not as devastating as surges coming from outside, but they will harm your home’s vulnerable electronics, such as televisions, computers and stereo equipment. The main cause of an internal surge is a sudden demand on the home’s electrical system. You may have noticed the lights dimming when the compressor in your refrigerator or air conditioner kicks on. This is the textbook definition of an internal surge.
Surge Protection Variables
There are three main ways that surge protectors should be judged: clamp level (when), surge strength (how much), and response time (how fast).
Clamp level refers to the voltage level that causes surge protectors to activate. In whole-house surge protectors, you should look for a clamp level of around 150 volts. For point-of-use, the clamp level should be an even lower 130 volts, because they are designed to protect the smaller, more sensitive electronics in your home.
Surge strength is the point at which surge protectors fail or sacrifice themselves. This is measured in amps of surge. You want whole-house surge protectors to be rated around 150,000 amps. A point-of-use surge protector can be a lesser 100,000 amps, because less power travels to specific points.
Response time refers to the amount of time it takes for a surge protector to activate after a spike has been detected. Quality devices activate so quickly that they are measured in nanoseconds! Point-of-use surge protectors need to be even quicker to protect at-risk electronics.
True surge protection should be handled by a professional electrician. Consumer-grade devices sold in most electronic stores are rated in joules. A joule is a measure of energy and is not a good standard of surge protection. The Institute of Electrical Engineers (IEEE) has published a warning that addresses joules as a measurement in surge protectors in IEEE C62, 33-1982, section 6.1. The warning states, “Users should be aware that energy rating (joule) does not necessarily mean a lower capability of survival.”
Do some Internet research. Talk to your neighbors. Call your Los Angeles Electrical Contractor. If you own a home, you should seek out additional information about surge protection. Think of a holiday without your dishwasher, an August night without your air conditioner, a lazy Sunday without your television, a Monday morning without your coffee maker… Feeling a little uneasy?
