With the 7-Outlet Pivot-Plug Surge Protector, you will always know whether or not your electronic devices are protected against damaging voltage fluctuations, surges, and spikes. The green "protected" indicator lets you know your equipment is secure, while the red "not grounded" indicator warns you when the electrical wiring is not properly grounded.
Please note: The protective components inside surge protectors absorb over-voltage spikes to protect your connected devices which means they will eventually wear out. Replace them every 3 years or immediately after any over-voltage spike event such as a thunderstorm or power outage because surge protectors degrade faster if they are exposed to high intensity events. Periodically check the surge protector enclosure and cable for signs of wear or heat distress. Replace an expired surge protector with a new one at the end of its useful life.With the 7 Outlet Home/Office Surge Protector, you never have to worry about power spikes, storms, voltage fluctuations, or transient electricity from damaging your valuable devices. Intelligent built-in voltage sensing circuitry detects and responds to your device's power needs, while safety features, such as thermal fuses that power off your system in the event of a severe occurrence, ensure that your devices are protected.
