Power surges have always existed, but the need for an effective whole house surge protector installation is greater than ever. We have more electronic devices in our homes than ever before. Those devices typically incorporate circuitry and microprocessors highly sensitive to voltage fluctuations. Did you know some of the largest power surges come from within your own home? It’s not always thunderstorms or other external activity. A power surge occurs when the voltage exceeds the normal flow of electricity. Power surges are transient spikes in voltage that usually last only a few millionths of a second but can permanently damage vulnerable electronics and appliances. A whole house surge protector is installed at you main panel. When it detects a surge, the suppressor automatically diverts the dangerously high voltage to ground instead of letting it enter the house’s circuits, leaving the electronics and appliances protected.
