Power-Back Surge occurs when power returns after a power-cut and connected equipments receives a surge of electricity at an over-voltage level. Most households experience power surges at some point. So here's what you can do to recognise the dangers and protect your home from electrical damage. Power surges occur when there's an unexpected interruption to the flow of electricity through the grid, or when a device that is supposed to draw electricity puts it back into the system instead.
