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.
#16 <<>> To load an extension cord to 1725 watts depending on the length of the cord, the bare minimum should be #14. A better size cord and my recommendation would be a #12 wire size extension cord.
It sounds like the outlet was wired by someone that didn't know what they were doing and installed the wrong size breaker ahead of the outlet. The main purpose of selecting the right size breaker to suit the wire is to prevent these conditions from happening.
In Canada this is quite acceptable. One extension cord can be plugged into another extension cord. What has to be kept in mind though, is the load amperage at the end of the cords. Additionally plugging one cord into another increases the wire's total resistance. This effects the over all voltage drop of the cord, by lowering the voltage at the load. If the cord's wire size is increase in each additional cord added to the length, this would be one way to combat against the voltage drop. An example, if the first cord has a #14 size conductor the next size cord to plug into it should be a #12. If additional length is needed then the next size cord to extend the length should be a #10.This type of cord use is used on construction sites all the time. Keep in mind that extension cords are only to be used as a temporary source of power in temporary locations and they not to be used as a permanent installation power source.
Yes, but with a heavier gauge wire <<>> If the cord on an electric heater needs to be lengthened as a perminant feature then the whole cord should be replaced with a new cord of the same type and wire size. What this prevents is aquiring bad splice connections at the point the connection is made. Bad splice connections will create hot spots in the cable. If the lengthening of the cord is just a temporary fix, just use an extension cord. The extension cord should be the same wire size as the heater cord. Keep the extension cord under 20 feet in length.
The wire size is large enough to carry the load current and that the cord is properly voltage rated.
When selecting a PFD, the most important consideration should be size.

The size you want your drawing to be.

With that size of load and a voltage of up to 300 or 600 volts, any extension cord can be used.
