Busting Myths about Lightning and Surge Protection: Separating Fact from Fiction

Lightning and surges can wreak havoc on electronic devices and electrical systems, making lightning and surge protection crucial for safeguarding our homes and businesses. However, navigating the vast sea of information can be overwhelming, leading to the perpetuation of myths and misconceptions. In this article, we debunk prevalent myths surrounding lightning and surge protection, shedding light on the facts to help you make informed decisions.

  1. Myth: Surge Protectors Are Only Necessary During Thunderstorms

Fact: Surges can occur at any time.

While lightning is a common cause of power surges, they can also result from everyday occurrences like utility switching, faulty wiring, or even appliances cycling on and off. A surge protector offers year-round protection, defending your valuable electronics from unexpected voltage spikes.

  1. Myth: All Surge Protectors Are the Same

Fact: Not all surge protectors are created equal.

Choosing the right surge protector involves more than picking the first one off the shelf. Consider factors like joule rating, response time, and clamping voltage. Higher joule ratings indicate better protection, while a lower clamping voltage ensures faster response to surges. Invest in a quality surge protector tailored to your specific needs for optimal defense against electrical threats.

  1. Myth: Surge Protectors Last Forever

Fact: Surge protectors have a lifespan.

Surge protectors degrade over time due to the cumulative effect of absorbing power surges. It’s essential to replace them periodically, especially if they have sacrificed themselves to protect your devices. Regularly inspect and replace surge protectors to ensure continued effectiveness.

  1. Myth: Unplugging Devices During a Storm Is Sufficient Protection

Fact: A surge protector provides a more comprehensive defense.

While unplugging devices during a storm may reduce the risk of damage, it’s not foolproof. Lightning can enter your home through various paths, including plumbing and wiring. Surge protectors, equipped with technologies like Metal Oxide Varistors (MOVs), offer a robust line of defense, minimizing the risk of damage to connected devices.

  1. Myth: Lightning Never Strikes the Same Place Twice

Fact: Lightning can strike the same place repeatedly.

The notion that lightning doesn’t strike the same place twice is a dangerous myth. Tall structures, such as buildings and towers, are susceptible to multiple strikes. Implementing proper lightning protection systems, including lightning rods and grounding, can mitigate the risks associated with repeated lightning strikes.

  1. Myth: Power Strips Provide Adequate Surge Protection

Fact: Power strips are not sufficient for robust surge protection.

While power strips offer additional outlets, they lack the necessary components to provide comprehensive surge protection. Investing in dedicated surge protectors designed to absorb and divert excess voltage ensures a higher level of defense for your electronic devices.

  1. Myth: Surge Protectors Can Withstand Unlimited Surges

Fact: Surge protectors have limits.

Surge protectors can handle a finite number of surges before their effectiveness diminishes. Continuous exposure to surges may wear them out over time. Regularly check the manufacturer’s guidelines and replace surge protectors as recommended to maintain optimal protection levels.


Q1: Are all surge protectors waterproof for outdoor use?
A1: Not all surge protectors are designed for outdoor use. Look for models specifically labeled as weatherproof or suitable for outdoor installations.

Q2: Can I use a surge protector with a power strip?
A2: Yes, you can use a surge protector with a power strip for additional outlets. However, avoid daisy-chaining multiple power strips together, as this can overload the circuit and reduce the effectiveness of surge protection.

Q3: How often should I replace my surge protector?
A3: Surge protectors should be replaced every 2-3 years, or sooner if they have experienced a significant surge event. Regular replacement ensures continued reliability.

Q4: Can lightning cause damage even if I have surge protection?
A4: While surge protectors provide a high level of defense, no system is entirely foolproof. Lightning can create powerful surges, so it’s essential to follow additional lightning protection measures, such as grounding and lightning rods.

By dispelling these myths, we hope to empower you with the knowledge needed to make informed decisions about lightning and surge protection. Stay vigilant, invest in quality protection measures, and create a safer environment for your electronic devices.
