A whole home surge protector is a device that shields your home’s electrical devices from voltage spikes. This occurs by limiting the supplied electricity to an electric device either by obstructing or shorting it to decrease the voltage down to a safer level. The purpose of this device is to prevent damage to electronic equipment from electricity surges, which can happen due to various reasons.
Working Principle of Whole Home Surge Protection
Surge protectors work by using a simple principle: any surplus electric charge will be channeled into the grounding wire inside the device. This keeps the voltage levels in your power lines at a safe level for your electrical devices. Here’s a step-by-step breakdown:
-
A voltage spike occurs in your power lines due to an external event like a lightning strike or internal event such as a sudden change in electricity usage.
-
This spike in voltage travels through your electrical system and into the surge protector, which is usually installed next to the main electrical panel.
-
The surge protector, powered by metal oxide varistors (MOVs), activates in response to the spike. MOVs are semi-conductors that have variable resistance based on voltage levels. MOVs react almost immediately to a voltage surge, diverting the excess electricity to the ground wire.
-
The surge protector thus stops the voltage spike before it can reach your home’s electrical devices, keeping them safe from power surges.
Choosing the Right Surge Protector
When buying a whole home surge protector, make sure to compare the joule ratings. The higher the joule rating, the more energy the device can absorb. Also, make sure it is compatible with your home’s voltage level. Installation of a whole home surge protector should be performed by a professional electrician, due to the risk of electrical injury.
If you are also considering an EV charger installation in Orlando, it’s crucial to install a surge protector for it as well. This device can prevent any voltage spikes from damaging your EV charger system.
Benefits and Drawbacks of Whole Home Surge Protection
Installing a whole home surge protector provides several benefits. It presents a first-line defense against power surges, protecting your precious electrical devices. This reduces the chance of losing important data on your computers, for example, due to unexpected power surges. The device also improves the lifespan of your electrical devices by limiting their exposure to voltage spikes.
However, they also come with drawbacks. Whole home surge protectors cannot provide total protection against extremely high spikes caused by lightning. They may also need replacement after a major surge. Additionally, the cost of purchasing and installing the device can be a deterrent to some homeowners.
Despite the drawbacks, investing in whole home surge protection can be seen as a safeguard for your valuable electronic devices from unpredictable voltage spikes. Coupled with individual surge protectors for sensitive devices, this investment can save you the hassle and cost of replacing damaged devices.
