Electrical surges are a common yet often overlooked threat to our homes. A surge is a sudden spike in electrical voltage that can damage or destroy your electrical devices, appliances, and even the wiring within your home. Understanding how to protect your home from these surges is crucial to safeguarding your valuable electronics and ensuring the longevity of your electrical systems. Here’s what you need to know.

Understanding Electrical Surges

Electrical surges can be caused by various factors, both internal and external. Common causes include:

• Lightning Strikes: One of the most significant sources of surges, lightning can produce a surge that travels through power lines, damaging anything connected to the electrical system.
• Power Outages and Restorations: When power is restored after an outage, the sudden influx of electricity can create a surge.
• Electrical Equipment: Large appliances, such as refrigerators, air conditioners, and power tools, can create surges when they cycle on or off.
• Faulty Wiring: Damaged or outdated wiring can lead to surges and other electrical issues within your home.

Understanding these causes can help you better prepare and protect your home from potential damage.

Install Surge Protectors

One of the most effective ways to protect your home from electrical surges is to install surge protectors. These devices are designed to absorb excess voltage and prevent it from reaching your appliances. There are two primary types of surge protectors:

1. Point-of-Use Surge Protectors: These are the most common type and can be found in various forms, such as power strips or wall-mounted outlets. They are typically used for individual devices like computers, televisions, and gaming consoles. When purchasing point-of-use surge protectors, look for those with a higher joule rating, as this indicates better protection.
2. Whole-House Surge Protectors: These are installed at your main electrical panel and provide comprehensive protection for your entire home. Whole-house surge protectors can protect against external surges, such as those caused by lightning, while also safeguarding your internal electrical systems.

Unplug Devices During Storms

During thunderstorms or severe weather, it’s wise to unplug sensitive electronics and appliances. Lightning can cause powerful surges that can bypass surge protectors, especially if they are not properly grounded. By disconnecting devices like televisions, computers, and gaming consoles, you can prevent potential damage from unexpected surges.

Maintain Your Electrical System

Regular maintenance of your home’s electrical system can help reduce the risk of surges. Schedule periodic inspections with a licensed electrician to check for issues such as:

• Outdated Wiring: Older homes may have wiring that cannot handle modern electrical demands. Upgrading to a newer system can help prevent surges and other electrical problems.
• Loose Connections: Poor connections can create resistance, leading to surges. An electrician can identify and fix these issues before they become problematic.
• Overloaded Circuits: Ensure that your circuits are not overloaded, as this can lead to surges and potential fire hazards.

Invest in Quality Appliances

When purchasing new appliances, opt for high-quality products that come with built-in surge protection features. Many modern appliances, particularly those with digital components, are designed to withstand minor surges. However, this doesn’t mean you should forego external protection; using surge protectors in conjunction with quality appliances offers the best defense.

Consider Insurance Coverage

Lastly, consider reviewing your homeowner’s insurance policy to ensure it covers damage from electrical surges. Some policies may have exclusions, so it’s wise to clarify what is covered and whether you need additional coverage.
