Is Placing a Surge Protector Extension Cable Behind a Microwave Safe?

Many households include a microwave in their everyday appliances. When dealing with electronics, it's essential to ensure safety and efficiency. This article will explore whether placing a surge protector extension cable behind a microwave is a safe practice.

Risk of Heating and Overloading

As Jacob pointed out, placing an extension cable behind a microwave can lead to overheating. Microwaves are high current appliances, and when an extension cable is coiled up or not properly rated to carry the current, it can get hot. This heat can accumulate, especially when the microwave is in use, leading to potential hazards.

Commercial Microwave Experience

A personal experience with a commercial microwave highlights the risks involved. Robert, who used to have a commercial microwave in his kitchen, faced weekly blown fuses. Upon investigation, the factory representative suggested that voltage spikes at night were causing the damage. To address this issue, Robert used a plug-type surge protector that fits directly into the outlet, thereby bypassing the plug strip issues.

General Safety Guidelines

Generally, it's advisable to avoid using extension cables with high-power appliances unless they are specifically designed and rated for the task. Other low-power units behind a TV, for instance, might necessitate extension cables. However, when it comes to microwave safety, it's crucial to consider the following:

Ensure the extension cable is rated to carry the current of the microwave oven or more. Avoid coil-up or tight bundling of the cable behind the microwave. Check for any signs of overheating or wear on the cable. Keep the area around the extension cable free from flammable materials like paper towels.

Conclusion

Placing a surge protector extension cable behind a microwave can be safe if the cable is properly rated and the conditions are managed. However, it's not a recommended practice due to the risks of overheating and potential damage. For maximum safety, the best approach is to use a plug-in surge protector directly into the outlet, especially if you're dealing with high-powered appliances like a microwave.

Additional Tips

Whenever using extension cables, especially those behind appliances, consider the following tips to enhance safety and efficiency:

Use only UL-listed and/or certified extension cables. Ensure that the cable and surge protector are properly grounded. Avoid using extension cables in areas where they could be exposed to moisture or physical damage. Regularly check the cable and surge protector for wear and tear.
