An air conditioner should be placed close enough to the outlet that the cord can easily reach it but if you are in a hurry and need immediate relief from the heat, you can get benefit from the extension cord for the air conditioner.
Make sure that what extension cord you choose for your AC should have the ability to handle that much load which is usually going up to 12 AMPS for mostly air conditioners. Where a 14 gauge extension cord can handle a reasonable amount of load, a 12 gauge extension cord for an air conditioner is considered safer and people believe that a 10 gauge extension cord is one of the best choices.
Do keep this fact in mind that extension cords are only recommended by the experts for temporary use with air conditioning. If your air conditioner unit is going to be placed for a long time or will be used on a regular basis, you should definitely replace your extension cord with a new outlet.
12 gauge extension cord for air conditioner
A 14 gauge extension cord can handle much of this current but we all know that air conditioners require more electricity and power when it comes to the initiation or starting up. This is the part where you need an extension cord of 12 gauge because it has the ability to easily handle this current in all situations of an AC.
You can easily find one of these hardware stores in the electric section but may not be found in a local general-purpose store. Most air conditioners now come with a three-prong connection, so make sure that you are looking for a three-prong extension cord for your air conditioner.
The ground connection should never be ignored because it will offer bigger benefits when it comes to issues like ground fault or power surge.
10 gauge extension cord for air conditioner
A larger number of gauge means the wire will be thinner in size, it eventually means that the wire will carry less power and may not be able to handle heavy appliances such as air conditioners. 10 gauge is probably the thickest and most powerful wire when it comes to different choices between extension cords.
Do keep this fact in mind that higher gauge extension cords will also work for shorter distances as they may not be able to transfer current consistently for a relatively long distance. A 10 gauge extension cord for the air conditioner can be 100 feet in length allowing you to cover a large area between your air conditioner and its outlet.
The length of the wire also affects the amount of current. For example, a 12 gauge extension cord of 25 feet can easily handle 16 to 20 amps of the current while the 10 gauge extension cord of 100 feet will carry this current without any hassle. It means that if there is a short distance, a 12 gauge extension cord may work perfectly but you definitely need a 10 gauge cord for a distance longer than 25 feet.
