The amperage rating of a cord is a function of the wire gauge number of current carrying conductors and length of the cord.

1 current ratings for up to 1000 v pvc insulated single and multicore wiring cables ambient temperature up to 30 o c values for resistance are based on electrical resistivity for copper 1 724 x 10 8 ω m 0 0174 μω m and electrical resistivity for aluminum 2 65 x 10 8 ω m 0 0265 μω m.
When a cord has three current carrying conductors there is a decrease in amperage.

These cables are rated for a voltage of 300 volts an ampacity of 10 amps have a temperature range of 20 c to 105 c and.
You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating.
