Avoid Plugging These 7 Appliances into Extension Cords

Understanding Extension Cord Limitations

While extension cords can be convenient for providing electricity to gadgets situated far from a wall socket, caution should be exercised. They are not suitable for all items, particularly for those with higher energy requirements.

Devices like fridges and toaster ovens, while electronic, require more power than what extension cords can generally offer, due to their higher amperage needs.

The Risks of Overloading Cords

Each extension cord has a specific limit on how much electrical current it can manage, tied to the wire gauge in use. For example, 16-gauge cords support up to 13 amps, while the thicker 14-gauge options handle about 15 amps, or 1,800 watts, matching a standard outlet in the United States.

Using a cord for a device that demands more electricity than it can handle risks overheating and fire hazards, as insulation can melt, exposing wires.

Appliances exceeding 1,800 watts should always be directly plugged into an outlet. Below are seven common household items that should never rely on an extension cord.

Appliances to Plug Directly into Outlets

1. Refrigerators

Despite not having heating elements, refrigerators are power-intensive as they run constantly. Over time, an extension cord may cause power inconsistencies, leading to operational failures.

2. Toasters and Toaster Ovens

These small devices, particularly toaster ovens, consume considerable electricity—up to 1,400 watts—despite their size. Plug them directly into outlets to avoid fire risks.

3. Air Fryers

Air fryers require significant heat to function, consuming up to 2,000 watts in larger models. Even a sturdy 14-gauge extension cord may not suffice, making a direct outlet connection safer.

4. Microwaves

Due to their high power usage, microwaves need dedicated circuits. Some models consume up to 1,000 watts, necessitating direct wall outlet access, particularly in homes with limited dedicated circuits.

5. Air Conditioners

AC units, whether portable or installed, draw excessive power for an extension cord, potentially causing fire hazards. Ensure these are directly connected to outlets, and calculate your space’s cooling needs with a BTU calculator to choose the right unit.

For example, a 150-square-foot room requires a unit that outputs approximately 6,500 BTUs or 1,905 watts.

6. Space Heaters

Quickly heating spaces are a key feature of portable space heaters, yet they pose fire risks. Producing about 5,120 BTUs per hour, they can overload cords, leading to melted plugs and fires.

7. Additional Extension Cords

Linking multiple extension cords is unsafe and causes circuits to overheat, leading to fires. Extension cords should never be used for devices drawing more than 15 amps.

Conclusion

It’s crucial to be mindful of what appliances are plugged where. Appliances requiring more than 1,800 watts need their own dedicated outlets to ensure safety and prevent hazards.
