Home power is not always consistent. Electricity flowing to your home cycles up and down throughout the day, depending on the demand of other homes and businesses in your power grid. You may not even notice these small power surges. However, when a power surge occurs, you will notice. The lights will get extremely bright and then go out quickly. Appliances and electronics will stop working, and you may notice a burnt plastic smell. This is one way to determine that the power surge was a severe situation. Home wiring systems can typically handle 120 volts of power, but with a severe power surge, the volts can exceed this amount. The wiring overheats and burns the plastic insulation. Mr. Electric of Chattanooga can install a whole home surge protector that can help protect your home from everyday power variance and power surges to save you money from expensive appliances and electronic replacements.

How Surge Protection Devices Work
A basic surge protection device on a power strip of outlets will govern electricity when it increases over a certain level, which is determined by the size of the capacitor. When the surge protector is tripped, it directs the excess power surge electricity into a grounding wire that is attached to the outlet the strip is plugged into. That grounding wire transfers electricity away from the outlet, which returns the voltage to a safe level.
If you are going to use power strip surge protectors, check the labels for these three different ratings:
- Clamping voltage: This is the voltage level that causes the surge protector to pass electricity to the ground wire on the outlet. The UL-approved devices have three ratings: 330 Volts, 400 Volts, and 500 Volts. If most wires can consistently handle 120 volts safely, then buy the surge protector strip with the lowest voltage rating you can afford.
- Energy absorption/dissipation: This rating explains how much electricity the surge protector can handle before it fails. A higher “joule” rating protects better—a surge protector with a capacity of 600 joules or higher offers good protection.
- Response time: A surge protector should respond in less than one nanosecond. The longer the response time, the longer your appliances and electronics will be suffering from a power surge. It doesn’t take long to burn out sensitive microchips in a computer or HDTV.
Standard electrical outlets can handle a surge protector power strip with breakers. Look for power strips that have working indicator lights. You also might want to consider:
- Equipment Warranties
- Automatic Warning Devices
- Power Shut Down Protection
- Resettable Circuit Breakers
- GFCI Protection
Some power strip surge protectors now have USB jacks, coax cable connectors, phone line jacks, and network plugs. Power surges also affect these kinds of wires as electricity is passed through devices that may be interconnected.
For example, a cable TV box receives power from a standard outlet and is connected to the coax cable to receive service. If there is a power surge through the power outlet connection, the additional electricity could travel through the coax cable to any other device (such as an HDTV) connected to the coax cable in another area of the house. Then, the power surge would affect that device as well.
