Danger: Extension Cords Ignite Fires
3 Dec
Summary
- Daisy-chaining cords causes overheating and fire risks.
- High-wattage appliances exceed cord capacity, posing hazards.
- Avoid cords for microwaves, air fryers, and space heaters.

Extension cords are a common solution for power needs, but their use is limited to electronics and should not extend to high-wattage appliances. Each cord has a maximum capacity based on its wire gauge, typically 1,800 watts for a 14-gauge cord. Exceeding this limit can cause the cord to overheat, melt insulation, and spark a fire. Appliances that demand more power should be connected directly to a dedicated circuit or wall outlet.
Several household devices present a considerable fire risk when plugged into extension cords. These include refrigerators due to their continuous operation, toasters and toaster ovens which consume significant energy, and air fryers that can reach 2,000 watts. Microwaves, AC units, and electric space heaters also draw excessive power, making extension cords unsafe. Connecting one extension cord to another, known as daisy-chaining, is particularly dangerous and can lead to overheating and combustion.
To ensure safety, it is imperative to connect any appliance requiring more than 1,800 watts directly to a wall outlet. This applies to microwaves, air fryers, AC units, and electric space heaters, which are noted as particularly risky. The Consumer Product Safety Commission reports that portable space heaters are involved in numerous fires annually. By understanding appliance wattage and cord limitations, users can prevent electrical hazards and protect their homes.
