Surge Protection


lightening storm

Since this is the time of year for tremendous lightning storms and heavy winds that can cause downed power lines, I thought I’d share some information on surge protection. Electrical surges are caused when higher than line voltages are inadvertently applied to the internal wiring of a building.

Most people have surge protection for their electronics in the form of power strips with built-in surge protection, and they are great, but they only protect the items plugged into them. What about your other electronics? Do you have one of the newer clothes washers? Dryer? Range? Microwave? If so, then a power surge could damage these items resulting in costly repairs. A whole house surge protection unit may be a good investment for your house. With whole house surge protection, all of the electronics in the house would then have surge protection. A whole house surge protector is installed in, or attached to, the main breaker panel. Some are even designed so that they replace one of the double pole (240 volt such as the range or dryer) breakers. Others mount to the outside of the panel.

A friend told me a few days ago that the control board went out on her kitchen range. When she had a service technician check the range, she was told that the part to fix her three-year-old range was no longer available, and if it were, it would cost $275.00 plus labor to install. Of course, we commiserated a bit about how things aren’t made the way they used to be, but the bottom line is that spending a few dollars for whole house surge protection may have prevented the damage. As the saying goes, “An ounce of prevention is worth a pound of cure.”

For more information on whole house surge protection, call a licensed electrician or visit the website for the manufacturer of your electrical panel. I have also included a link to a great article on the This Old House website.

Electrical Wiring – Do NOT Try This at Home!


At Least This Guy Survived!

Electrical wiring is best left to the professionals. In order to become a licensed electrical contractor in the state of South Carolina, one must meet several qualifications. The first is a minimum of two years experience under the supervision of a licensed electrician. Secondly, one must pass the master electrical exam and business exam: 80 questions, four hour time limit-50 questions, 3 hour time limit, respectively. Which means that you have about three minutes per question. Thirdly, once the exam have been passed, (most don’t make it this far!) you must submit your application to the state for an electrical contractor’s license. Oh, and you must complete the Code of Laws Take Home exam, 40 questions, and submit it with your application. Lastly, one should obtain a minimum one million dollar liability insurance policy, just in case. Fees, I almost forgot the fees, about $700 in fees just to get started.

Why is it so hard to get an electrical license? The reason is to protect you! 

Electrical contractors are held to a high standard of professionalism. Our work is subject to inspection by officials that are employed by the jurisdictions in which we work. We have a code that we are required to follow, the National Electrical Code, an 870 page book of regulations that is updated every three years. The purpose of the Code is: Article 90-Practical Safeguarding. The purpose of this Code is the practical safeguarding of persons and property from the hazards arising from the use of electricity.


Do yourself a favor, the next time you need some electrical work done don’t call your brother-in-law because he once hung his own ceiling fan, call a professional. And, by the way, when you get the bill, try to remember what I’ve said about the journey to be an electrical contractor. Your electrical contractor has invested literally thousands of dollars into becoming the professional that you want working in your home.
