Extension cords are mostly a safe solution for moving powerfulness to electronics that are excessively acold from nan nearest wall outlet. But nan operative connection present is "electronics," which is not arsenic all-encompassing arsenic immoderate group mightiness think.
Appliances (like refrigerators and toaster ovens) are evidently physics devices, but they're successful a different people from astir electronics because of nan amperage demands they request to function.
Why you shouldn't plug everything into an hold cord
Extension cords are manufactured pinch a maximum capacity to grip electrical current, which is wished by nan size aliases gauge of nan ligament utilized successful nan cord. For instance, a 16-gauge hold cord tin grip a maximum of 13 amps, while a 14-gauge cord tin grip up to 15 amps (or 1,800 watts), nan aforesaid arsenic a modular wall outlet successful nan US.

When an appliance demands much powerfulness than nan hold cord tin handle, it results successful an overload, which could lead to overheating. You really don't want your cord's insulation to melt, exposing nan unrecorded wires and perchance sparking a fire.
Any appliance requiring much than 1,800 watts should beryllium connected a dedicated circuit -- ne'er connected by an hold cord. And nan pursuing are 7 family devices you'll decidedly want to link straight to an outlet.
1. Refrigerators
Refrigerators don't person heating elements and usage little wattage than different room appliances, but they still request a fierce magnitude of powerfulness because they're perpetually running. While nan occurrence consequence is simply a spot little pinch fridges, an hold cord could still origin nan fridge to modulate its powerfulness and malfunction.

2. Toasters aliases toaster ovens
Despite their comparatively mini size, toasters devour important power and tin beryllium a occurrence hazard erstwhile plugged into hold cords. Toaster ovens are larger and require moreover much power, typically ranging from 1,200 to 1,400 watts. Keep your toast-making and mini baking projects safe by opting for a wall outlet.
3. Air fryers
Air fryers are fantabulous for making leftover French fries crisp again. But that requires a batch of heat, and larger models tin devour arsenic overmuch arsenic 2,000 watts -- this poses a sizeable occurrence consequence erstwhile plugged into moreover a 14-gauge cord. The aforesaid applies to powerfulness strips.
To guarantee safety, it's champion to spot nan aerial fryer connected nan countertop and plug it straight into a dedicated wall outlet during use, moreover if that intends pulling it retired of nan furniture only erstwhile needed.
4. Microwaves
A microwave is different heavy-duty appliance that should person its ain dedicated circuit owed to precocious wattage. Compact microwaves, for illustration those you find successful edifice rooms aliases RVs, person an mean wattage of 600 to 800 watts. Standard microwaves, typically installed successful homes and workplace breakrooms, usage 800 to 1,000 watts.

While nan second would often beryllium installed amid cabinets pinch a dedicated circuit, immoderate homes only connection antagonistic abstraction for specified a hefty appliance. If that's your scenario, beryllium judge to plug it straight into a crushed responsibility circuit interrupter (GFCI) outlet successful your kitchen.
5. AC units
AC units, whether portable aliases window-installed, usage excessively overmuch powerfulness for hold cords aliases powerfulness strips. So, beryllium judge to connect them straight to a wall outlet arsenic well. Before doing that, besides beryllium judge to usage an online BTU (British Thermal Unit) calculator to find nan type you will request to cool your abstraction effectively.
Cooling a emblematic chamber -- astir 150 quadrate feet -- requires a portion tin of utilizing 6,500 BTU aliases 1,905 watts. This magnitude of tie is acold excessively precocious for an hold cord to grip and could consequence successful a fire.
6. Space heaters
As bully arsenic it is to beryllium capable to quickly move connected and disconnected that electrical abstraction heater, it's considered 1 of nan riskier family appliances successful position of causing a fire. According to nan Consumer Product Safety Commission (CPSC), portable abstraction heaters are progressive successful an mean of 1,700 fires per twelvemonth successful nan United States, pinch immoderate of those resulting from hold cord use.
That's because they typically nutrient astir 5,120 BTUs per hour, easy beardown capable to melt an hold cord plug.
7. Extension cords
We've each done it: connecting 1 hold cord to different successful an effort to daisy-chain a instrumentality to a powerfulness outlet. This is simply a awesome no-no successful nan onshore of energy distribution. It could lead to a circuit overheating, which past causes nan cord to overheat and commencement burning. Although a cord isn't technically an appliance, it's important to cognize there's an inherent threat successful connecting 1 to another.

The bottommost statement is that hold cords shouldn't beryllium utilized for immoderate system that draws much than 15 amps (1,800 watts), sloppy of what it's utilized for aliases wherever nan instrumentality is situated.
