All extension cords have an AWG (American wire gauge) rating. This rating is a standardized wire gauge system for measuring electrical wire. A lower AWG number indicates a thicker wire and a higher capacity. The lower the number, the higher the cord’s capacity to deliver power.
Which is better 10 gauge or 12 gauge extension cord?
Round down = 10 Gauge. Most devices will do fine with 12 gauge extension cords. Power hungry devices such as lawnmowers, heavy machines, require a lower gauge such as 10AWG. Keep in mind, the lower the gauge means the thicker the cord.
What happens if extension cord is too long?
An improperly sized extension cord can cause a tool or appliance motor to burn out if allowed to run for too long. It can also cause a dangerous situation if it overheats.
What gauge extension cord should I use?
Recommended wire gauge for extension cords A cord measuring 14 AWG is the thinnest we recommend—and at lengths of only 25 feet or shorter—and the much thicker 10 AWG is likely the thickest gauge you’ll find in an extension cord.
Can a 12 gauge extension cord handle 30 amps?
A 12-gauge aluminum extension cord has a rating of 20 amps at 167°F and 25 at 194°F. On the other hand, a copper wire of the same AWG has a rating of 25 at 140°F, 25 at 167°F, and 30 at 194°F.
Can I use a 12 gauge extension cord on a 15 amp circuit?
A short 12 gauge extension cord of 50 ft or less can handle up to 20 amps intermittently. Anything over 50 ft should be limited to around 15 amps. Under those loads the cord should always be fully unrolled and checked frequently for heat, particularly at the connections.
Is 16 gauge or 12 gauge extension cord better?
Common household extension cords are available in 16 gauge (smallest), 14 gauge, 12 gauge, and 10 gauge (biggest). The lower the number, the bigger the gauge and the greater the amperage and wattage is.
How many amps can my extension cord handle?
16-Gauge Cords: Any 16-gauge cord between 0 and 100 feet long will adequately handle tool loads up to 10 amps. 14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and 15 amps.
Can an extension cord handle 1500 watts?
Extension cords usually can’t handle high current Medium-sized space heaters draw around 1,500 watts and 12.5 or more amps. That is what most extension cords can barely handle. The rating for your extension cord could be anything between 10-15A. It’s like you’re walking on the edge of a cliff.
What is considered a heavy-duty extension cord?
A 10- to 12-gauge wire is considered a heavy-duty extension cord, a 14-gauge wire is a medium-duty cord, and a 16-gauge wire is a light-duty cord.

What gauge is a 30-amp extension cord?
That’s why you really need at least a 10-gauge extension cord for any 30-amp circuit. As you can see from the chart above, it’s rated for 30 amperes of current so it will have much less voltage drop (easily half as much as a 14 gauge cable with the same current). Plus there will be much less heating.
Is a 14 gauge extension cord heavy duty?
Frequent use cords. A 14-gauge cord is for medium or frequent duty applications (lawnmowers, power drills, table saws, television sets, etc.). These cords are also great for things like power tools, electric chainsaws, leaf or snow blowers, etc. They can handle larger tools and equipment and heavier use.
Do extension cords draw more electricity?
No, an extension cord (short of long) does not draw (consume) any power so there is no way for the cord itself to increase your bill. An extension cord only conveys power to the devices plugged into it – if those devices are actually turned on.
Do long extension cords lose power?
Long extension cords can cause significant drops in voltage to appliances. Anything that resists the flow of electricity causes voltage to drop. … Whether an extension cord causes a noticeable or significant voltage drop depends on the length and gauge of the wire and the appliance plugged into it.
What gauge extension cord do I need for Christmas lights?
For running Christmas lights, you want to make sure that any cord you use is rated for outdoor use. Pick a 16-gauge extension cord for light runs of 25 feet or less and go with a heavier duty 14-gauge cord for runs over 25 feet.
Can you run a space heater off an extension cord?
Space heaters must be plugged directly into a wall outlet, which can handle a higher wattage, and should be the only item plugged into that wall outlet. The Electrical Safety Foundation International says space heaters can overheat a power strip, as well as an extension cord, and potentially cause a fire.
How many amps can 18 gauge wire handle at 12 volts?
A conservative estimate for several feet of 18 gauge wire is 16 Amps. If you have only 12 gauge wire, the 18 gauge wire can handle more than 16 Amps.
Can I use a heavy duty extension cord with space heater?
ANSWER: DO NOT USE AN EXTENSION CORD OR POWER STRIP WITH AN ELECTRIC ROOM SPACE HEATER. IT CAN OVERLOAD THE CIRCUIT OR OVERHEAT THE EXTENSION CORD AND CAUSE AN ELECTRICAL FIRE. SETTING THE SPACE HEATER THERMOSTAT HIGHER WILL NOT MAKE IT SAFER.
Can I run 300 ft of extension cord?
In general, extension cords should not exceed 100 feet in length. However, by plugging one extension cord into another, the maximum cord length can be easily exceeded. If the job requires more than a 100-foot distance, a temporary power distribution box is required.
Can I use a 12 gauge extension cord for my RV?
For RV’s that need to get 15A power, we recommend using a 10 Gauge Extension Cord. This is a good cord to run at any length, as it has a very durable jacket, and thick stranded wire. At minimum we recommend using a 12 gauge extension cord.
Can a 10 gauge extension cord handle 30 amps?
30 Amp RV Extension Cord Gauge For the 3,600 watts that a 30-amp cord can handle, you’ll want a 10 AWG extension cord. Remember: the longer the extension cord, the lower the AWG number required.
What is the longest 30 amp RV extension cord?
The actual answer is: “there is no maximum, as long as it is rated for 30 amps“. The question should be not how many feet, but how many cords. A 100 ft extension cord rated for 30 amps is not the same, at all, as two 50 foot 30 amp extension cords.
