When electrical appliances and devices are exposed to sudden power surges, whether it’s an increase or decrease of voltage, appliances plugged in during this duration can start to malfunction, and may even cause fires in the most extreme cases.

This is why, it’s necessary for homeowners to have power surge protectors in place at their homes to protect their appliances, devices, and electrical fittings from experiencing the aftereffects of power surges.

Cost of Buying Them

Cost of Installation

However, the choice is ultimately yours if you would rather purchase a single surge protector or a whole house surge protector, and it also depends on how frequent power surges are in your area, and the intensity of them.
