Understanding Whole-Home Surge Protection
A power surge is a sudden increase in electricity flowing through a circuit, which can have detrimental effects on the home’s wiring, outlets, switches, and electrical appliances. Lightning strikes, downed power lines, and fluctuations in electricity usage can all contribute to power surges. It is crucial to understand whole-home surge protection to safeguard your electrical system and appliances from potential damage.
At the core of whole-home surge protection is the surge protector, a device designed to continuously monitor the voltage of the current entering the home and within the electrical system. When it detects a dangerous increase in voltage, the surge protector diverts the excess voltage to the ground wire, effectively grounding the power and preventing it from flowing through the electrical system.
Surge protectors act as pressure-relief valves, shielding your home’s electrical system and appliances from the harmful effects of power surges. By diverting excess voltage, surge protectors ensure that only safe levels of electricity flow through your electrical system, mitigating the risks of damage and costly repairs.
There are different types of surge protectors available:
