Overvoltages are up to 20 times higher than normal operating voltages – Equipment at home is vulnerable to damage

Overvoltages can be caused by lightning strikes that hit a property directly or close to a property. Lightning overvoltages can travel to a property from the supplying electricity network, outside cables of the property, telephone lines, aerial leads, and data cables. Overvoltages and the damages they cause can be prevented with the correct overvoltage protection.
