A #12 copper wire is rated at 20 amps. On an extension cord, unless it has user installed ends, the rating of the three blade cap is only 15 amps. Either way the extension cord should only be loaded up to 80% of the wire rating. 20 x .8 = 16, 15 x .8 = 12.
It is not recommended to plug a 15 amp extension cord into a 20 amp breaker because the extension cord may overheat and pose a fire hazard. It is safer to use a cord that matches the amp rating of the breaker to prevent potential electrical issues.
Yes the rated voltage is a maximum. A 250 v cord might be slightly thicker than one for 125 v. <<>> The voltage rating of an electrical extension cord is the insulation factor of the cord. These cords come in two insulation ratings, 300 volts and 600 volts. If the voltage rating is within the parameters of the cord maximums then it is safe to use it on that voltage. The amperage of the cord is based on the wire size of the cord's conductor. The rating of 10 amps will fall within the #14 cord size. Remember the longer the cord the larger the wire size should be to prevent voltage drop at the connected load end.
If your extension cord is truly a 30 amp cord then it is composed of #10 wire. #10 wire is rated at 30 amps. All you have to do is remove the 30 amp plug and receptacle ends from the cord and install 15 amp cord ends.
When purchasing an extension cord it is important to make sure you get one that is large enough to handle the voltage needed. There are some guide lines available through home improvement websites that can help in the buying process.
If your question is can you use a #6 flexible SOOW cord and put a 30 amp plug on it, then yes. The breaker that feeds the receptacle that the cord will plug into can be no larger than a 30 amp breaker. What limits the cord capacity to 30 amps is the ratings of the plug on the end of the cord.
The maximum amperage rating for a 15 amp extension cord is 15 amps.

The maximum amperage rating for a 40 amp extension cord is 40 amps. To safely use it for powering high-current devices, make sure the devices do not exceed the cord's amperage rating. Also, avoid overloading the cord by connecting multiple high-current devices at the same time. Regularly inspect the cord for any signs of damage and replace it if needed.

yes.
no, you should use same amp and volt.

For a 30 amp circuit, it's recommended to use an extension cord that is no longer than 50 feet to minimize voltage drop and ensure safety. Additionally, the extension cord should be rated for at least 10-gauge wire to handle the current safely. Always check local electrical codes and guidelines to ensure compliance with safety standards.
For a 5500-watt generator, you should use an extension cord rated for at least 20 amps to safely handle the electrical load. Make sure the extension cord is in good condition and of the appropriate gauge to prevent overheating and ensure safe operation.
A 14 gauge extension cord can safely carry 15 amps, but not very far. Number 14 gauge extension cords are only rated for about 13 amps according to the labels on the cord. This is because the insulation is not intended to withstand the heat of currents above this level. Running this cord over 50 feet or loading it to 18 amps would be unacceptable.The likelihood of the cord maintaining the 18 amps for any amount of time for the high current to do any damage to the insulation of the cord is not very great. Extension cords are only an extension of the 15 amp wall circuit that they are plugged into. On overloading the extension cord by that amount the overload will trip the 15 amp supply breaker. An example of this is jamming a circular handsaw when it is plugged into the end of a 50 foot extension cord. The next action that is taken is to reset the tripped breaker.
