Surge protectors play a crucial role in safeguarding our electronic devices from voltage spikes, which can cause irreparable damage. However, like any other device, surge protectors can become faulty over time, losing their protective capabilities. It's essential to test your surge protector power strip regularly and know how to replace it if it fails to ensure continuous protection for your valuable electronics. This article guides you through the process of testing and replacing a faulty surge protector power strip.
Understanding Surge Protectors
Before diving into testing and replacement procedures, let's briefly understand what surge protectors do. A surge protector power strip diverts excess voltage away from connected devices during a surge, typically through a component called a metal oxide varistor (MOV). Over time, the MOV can degrade due to repeated exposure to surges, diminishing the effectiveness of the surge protector.
Signs Your Surge Protector May Be Faulty
- Visible Damage: Look for signs of wear, such as frayed wires, burn marks, or melted plastic.
- Indicator Light: Many surge protectors have an indicator light that shows whether the protection is active. If this light is off or flickering, it may indicate a problem.
- Age: If your surge protector is over three years old, it might be time for a test, even if there are no visible signs of failure.
Testing Your Surge Protector
Visual Inspection
Start with a thorough visual inspection. Check for any signs of physical damage as mentioned above. Also, ensure that the power switch (if present) is functioning correctly and that the surge protector is not overloaded with too many devices.

Using the Built-In Test Function
Some surge protectors come with a built-in test function. Consult the user manual and follow the instructions to test the unit. Typically, this involves pressing a test button and observing if the indicator lights behave as expected.
Multimeter Testing
For a more hands-on approach, you can use a multimeter to test the surge protector.

- Preparation: Disconnect all devices from the surge protector and turn off the power.
- Testing Continuity: Set your multimeter to the continuity setting. Test each outlet by inserting one probe into the hot slot (shorter slot) and the other into the ground. The multimeter should beep or show a reading close to zero, indicating continuity. Repeat for the neutral slot (longer slot) to ground. Lack of continuity suggests a fault.
- Testing Protection: Unfortunately, without specific equipment, testing whether the MOV is still functional is challenging for the average consumer. The lack of continuity or visual/indicator signs of damage might be the only practical way to assess its condition at home.
Replacing Your Surge Protector
If you find that your surge protector is faulty, it's crucial to replace it immediately to ensure your devices are protected. Here's how:
Choosing a Replacement
- Joule Rating: This rating indicates the amount of energy the surge protector can absorb before failing. Higher numbers offer better protection.
- Response Time: Look for surge protectors with a response time of one nanosecond or less.
- Outlets and USB Ports: Consider how many outlets and USB ports you need. Ensure there's enough spacing for large adapters if necessary.
- Warranty: Some manufacturers offer warranties that cover damage to connected equipment. This can be a sign of the manufacturer's confidence in their product.
Proper Disposal
Dispose of your old surge protector responsibly. Do not simply throw it in the trash as it contains components that can be harmful to the environment. Many electronic stores offer recycling programs for such items.

Installation of the New Surge Protector
- Location: Place your new surge protector in a location where it won't be covered by furniture or carpeting, as it needs proper ventilation to prevent overheating.
- Connection: Connect your devices to the surge protector. Avoid daisy-chaining surge protectors together, as this can be dangerous and might void any connected equipment warranty.
Conclusion
Regularly testing and promptly replacing faulty surge protectors is key to ensuring the longevity and safety of your electronic devices. While the testing process can be somewhat limited for the average consumer, being vigilant about signs of wear, understanding the limitations of your surge protector, and choosing a high-quality replacement can significantly mitigate the risk of damage caused by voltage spikes. Remember, a surge protector is an investment in the protection of all your electronic devices.
