Which is better 12 gauge or 14 gauge extension cord?
In my personal experience, the gauge of an extension cord is an important factor to consider when choosing the right one for your needs. When it comes to the question of whether a 12 gauge or 14 gauge extension cord is better, it really depends on the specific situation.

For a 100-foot cord, a 12 gauge cord is best designed to handle 14-15 amps, while a 14 gauge cord is rated for 11-13 amps. This means that if you need to power something that requires more than 13 amps, you should opt for the 12 gauge cord. However, if your power needs are less than 11 amps, the 14 gauge cord should suffice.

On the other hand, if you need a longer cord, such as a 150-foot cord, the 14 gauge cord is only ideal for 1-7 amps, while the 12 gauge can handle 8-10 amps. This indicates that the length of the extension cord is also a factor in the power it can provide. Therefore, if you need to power something that requires more than 7 amps over a longer distance, you should opt for the 12 gauge cord.

In summary, when choosing between a 12 gauge and 14 gauge extension cord, consider the following:

  • The length of the cord
  • The power needs of the device you are powering
  • The amperage rating of the cord
  • The distance the power needs to travel

By taking these factors into account, you can choose the right extension cord for your needs and ensure that your devices are powered safely and effectively.
