Surge protector
Due to the global temperature phenomenon, a lot of unpredictable weather has been occurring in the world, such as thunder storms, lightning & heavy rains tends to happened frequently. These harsh weathers can be harmful to expansive electronically equipments for example; lightning strike may burn the circuitry thus resulting in expensive repairs.
As a precaution method, it is wise to install surge protectors as it will receive the lightning so damaging it rather than the expensive electronic devices.
