As summer approaches, relying on your AC for relief is common, but there’s a vital safety precaution: avoid plugging air conditioners into extension cords. This fire safety measure is crucial for protecting your home.
The Danger of Using Extension Cords with High-Power Appliances
While seemingly convenient, particularly with limited outlets, using extension cords for high-wattage appliances poses a significant fire risk. Appliances like air conditioners, freezers, and cooking appliances require direct connection to a wall outlet for safe operation. Opting for extension cords or power strips may offer immediate ease, but it can jeopardize your home’s safety as temperatures rise.
Experts emphasize the widespread lack of awareness regarding extension cord limitations. Using an inadequate gauge cord for appliances with heating elements, such as toaster ovens or microwaves, can lead to overheating and potential fires. This is because the cord might not handle the required amperage.
While 14-gauge and 12-gauge extension cords are common, it’s important to note their limitations. A 14-gauge cord typically supports up to 1,800 watts (15 amps), matching a standard US wall outlet. However, for appliances exceeding 1,500 watts, a dedicated circuit is strongly advised.
To ensure safety, it’s crucial to know which appliances should never be connected to extension cords. Here are seven critical items to keep in mind.
Appliances That Shouldn’t Be Plugged Into Extension Cords
- Air Fryers
- Microwaves
- Extension Cords
- Space Heaters
- Toasters & Toaster Ovens
- Fridges
- Air Conditioning Units
1. Air Fryers
Air fryers offer a convenient way to prepare food quickly; however, they should not be connected to extension cords. Larger air fryers can consume up to 2,000 watts, representing a significant fire hazard with extension cord usage. When counter space is limited, use the appliance only when needed and plug it directly into a dedicated wall outlet.
2. Microwaves
Though some homes have built-in models, standalone microwaves are high-wattage appliances that require a dedicated circuit. Connecting a microwave to an extension cord can overload the circuit and create a fire hazard.
3. Extension Cords
Connecting extension cords to each other, known as “daisy chaining,” is extremely dangerous. This practice overloads the circuit, potentially causing overheating, melting, and ultimately, a fire. Avoid daisy-chaining extension cords at all costs.
4. Space Heaters
Electric space heaters have long been identified as a major cause of residential fires. Using extension cords with space heaters significantly increases this risk. According to safety authorities, portable space heaters are involved in numerous fires annually, some resulting in fatalities. Therefore, a direct connection to a wall outlet is essential.
5. Toasters and Toaster Ovens
Toasters, while small, demand significant energy. Toaster ovens draw even more power, typically between 1,200 and 1,400 watts. Connecting these appliances to extension cords presents a considerable fire threat due to the high energy consumption.
6. Refrigerators
Refrigerators, consuming between 300 and 800 watts, run continuously. While their power draw is less than other appliances, extension cord use is discouraged. A faulty connection may lead to malfunction or, in severe cases, a fire. It’s always preferable to plug your refrigerator directly into a wall outlet.
7. Air Conditioning Units
Air conditioning units demand substantial power to cool your home effectively, emphasizing the need for direct wall outlet connection. It is also vital to select the appropriate size AC unit for your space. Using an undersized unit can cause it to overwork, increasing energy consumption. This can lead to higher electricity bills and, if connected to an extension cord, a heightened fire risk. Use a BTU calculator to determine the correct unit size for your room.
Key Considerations When Using Extension Cords
- Never use with appliances above 15 amps (1,800 watts).
- Always plug into a wall outlet.
- Avoid daisy-chaining cords.
The Bottom Line on Extension Cords: Safety First
Prioritize safety by avoiding extension cord use with appliances. Utilize power strips exclusively for electronics. Always remember that standard household extension cords are designed for a maximum of 15 amps (1,800 watts). Whether at home or elsewhere, always observe these guidelines.
