Surge Protection

Power surges may result in damage to electrical devices within the home. Many homeowners choose to install surge protectors, which regulate the voltage supplied to an electronic device by diverting excess electricity through a grounding wire. Common plug-in surge protectors plug into a single wall outlet and feature a hub into which several electronic devices can be plugged, offering moderate protection to those devices.

Whole-house units, which protect all electric devices within the home, are also available. These are installed by an electrician at the meter or at the service panel. A whole-house unit monitors voltage levels entering the home. Whole-house units only protect from incoming surges. They should be used in conjunction with plug-in units to fully protect against voltage fluctuations originating either within or from outside the home.
