Extension cords are usually a protected resolution for working energy to electronics which can be too removed from the closest wall outlet. However the operative phrase right here is “electronics,” which isn’t as all-encompassing as some individuals may assume.

Home equipment (like fridges and toaster ovens) are clearly digital units, however they’re in a special class from most electronics due to the amperage calls for they should perform.Â
Why you should not plug every little thing into an extension wire
Extension cords are manufactured with a most capability to deal with electrical present, which is set by the dimensions or gauge of the wire used within the wire. As an illustration, a 16-gauge extension wire can deal with a most of 13 amps, whereas a 14-gauge wire can deal with as much as 15 amps (or 1,800 watts), the identical as a normal wall outlet within the U.S.
When an equipment calls for extra energy than the extension wire can deal with, it ends in an overload, which may result in overheating. You actually don’t desire your wire’s insulation to soften, exposing the dwell wires and doubtlessly sparking a fireplace.
Any equipment requiring greater than 1,800 watts ought to be on a devoted circuit — by no means linked by an extension wire. And the next are seven family units you may undoubtedly wish to join on to an outlet.
1. Fridges
Fridges do not have heating components and use much less wattage than different kitchen home equipment, however they nonetheless demand a fierce quantity of energy as a result of they’re consistently working. Whereas the fireplace danger is a bit decrease with fridges, an extension wire may nonetheless trigger the fridge to modulate its energy and malfunction.

2. Toasters or toaster ovens
Regardless of their comparatively small measurement, toasters eat important vitality and is usually a hearth hazard when plugged into extension cords. Toaster ovens are bigger and require much more energy, sometimes starting from 1,200 to 1,400 watts. Preserve your toast-making and small baking tasks protected by choosing a wall outlet.
3. Air fryers
Air fryers are glorious for making leftover French fries crisp once more. However that requires a great deal of warmth, and bigger fashions can eat as a lot as 2,000 watts — this poses a substantial hearth danger when plugged into even a 14-gauge wire. The identical applies to energy strips. To make sure security, it is best to put the air fryer on the countertop and plug it straight right into a devoted wall outlet throughout use, even when meaning pulling it out of the cupboard solely when wanted.
4. Microwaves
A microwave is one other heavy-duty equipment that ought to have its personal devoted circuit resulting from excessive wattage. Compact microwaves, like these you discover in lodge rooms or RVs, have a median wattage of 600 to 800 watts. Normal microwaves, sometimes put in in houses and office breakrooms, use 800 to 1,000 watts. Whereas the latter would usually be put in amid cupboards with a devoted circuit, some houses solely supply counter house for such a hefty equipment. If that is your state of affairs, you’ll want to plug it straight right into a floor fault circuit interrupter (GFCI) outlet in your kitchen.

5. AC items
AC items, whether or not transportable or window-installed, use an excessive amount of energy for extension cords or energy strips. So, you’ll want to connect them on to a wall outlet as nicely. Earlier than doing that, additionally you’ll want to use an internet BTU (British Thermal Unit) calculator to find out the sort you will want to chill your house successfully. Cooling a typical bed room — about 150 sq. ft — requires a unit able to utilizing 6,500 BTU or 1,905 watts. This quantity of draw is much too excessive for an extension wire to deal with and will end in a fireplace.
6. Area heaters
As good as it’s to have the ability to rapidly activate and off that electrical house heater, it is thought-about one of many riskier family home equipment when it comes to inflicting a fireplace. In response to the Shopper Product Security Fee (CPSC), transportable house heaters are concerned in a median of 1,700 fires per 12 months in the USA, with a few of these ensuing from extension wire use. That is as a result of they sometimes produce round 5,120 BTUs per hour, simply robust sufficient to soften an extension wire plug.

7. Extension cords
We have all finished it: connecting one extension wire to a different in an try and daisy-chain a tool to an influence outlet. It is a main no-no within the land of electrical energy distribution. It may result in a circuit overheating, which then causes the wire to overheat and begin burning. Though a wire is not technically an equipment, it is essential to know there’s an inherent hazard in connecting one to a different.
The underside line is that extension cords should not be used for any mechanism that attracts greater than 15 amps (1,800 watts), no matter what it is used for or the place the machine is located.
