Can i use 220v extension cord in a 110v outlet

not all wire is rated for 600 volts. A typical example would be SJO cord compared to SO cord. The J in the SJO stands for junior which indicates it is 300 volt rated.

still over the 120 volts (to ground) needed in a typical extension cord but there is a difference.

It is possible that the cord is a 20 amp 120 volt cord and the outlet is 15 amp. The 20 amp 120 volt plug looks very similar to the 20 amp 220 plug. If the outlet is 15 amp it would not have the extra side ways slot and the plug would not fit evan though it was the same voltage. If you type NEMA plug chart into a search online you can look at all of the different plugs.
