Ones with a high ambient temperature rating can carry high loads of power. Having a higher ampacity means it can allow more current to flow at any given time. In other words, an 8-gauge copper wire can support more ampacity than the equivalent aluminum one. There are a few of these for the ambient temperature rating, so keep that in mind.Ĭopper can carry more ampacity than aluminum at the same AWG. If you are using a copper wire, you must refer to the copper column. When using aluminum as the material, you will refer to the aluminum column. It is important to know the conductive material you plan to use. The AWG wire for a certain ampacity depends on a few factors, such as the conductive material and the ambient temperature rating. If you seek one out for your washing machine, you can use the chart above as a guide. Similarly, you can use a 14-gauge copper wire for 220V 20 amps at 167☏. The chart above indicates that a 12 aluminum wire is a safe choice for your 220V 20 amps at 167☏ ambient temperatures.

The appropriate amp rating is crucial to ensure it can handle the electrical amount according to your requirements! It depends on the wattage and size you require.

It will help you realize which option is right for you, whether it’s 10 or 14. It determines how many amps a particular AWG wire can handle. Electrical Extension Cord Gauge ChartĪs for wires, we also have an extension cord gauge chart. It is dangerous to use it with a space heater or any heat-generating appliance, such as toasters. This type can only support devices that are not power-hungry. Best 16 gauge extension cordĪ 16-gauge extension cord has a rating of 13 amps, which you can use for a light-duty job. It has a rating of 20 amps at an ambient temperature rating of 140☏ and 167☏ and 25 at 194☏. In the case of a 14-gauge extension cord, it usually only uses copper for the conductive part. $23.99 Buy on Amazon Best 14 gauge extension cord It is best practice to check the specifications. Some thick extension cords are waterproof. What extension cord size do I need for 15 amps?Ī 6-gauge aluminum extension cord has a rating of 50 amps at an ambient temperature of 167☏ or 60 at an ambient temperature of 194☏.Ī 6-gauge copper extension wire has a rating of 55 amps at an ambient temperature of 140☏.How much do extension cords with different gauges cost?.

With that said, people need to know how to prevent them from failing. The main reason it is dangerous is the incorrect size and use. In a recent study by the US Consumer Product Safety Commission, extension cords are among the most dangerous electrical products for home use. The most common length are 25 ft, 50 ft, 100 ft, and 200 ft. If you have ever been to an electrical supply store, you will notice they come in different lengths and sizes. We picked extension cords with different capabilities to reflect the different needs people have. We have also written extensively on electrical topics and feel we know what we’re talking about.
