What's the point of 10 evaluate extension cords IF the line within the house is #12?
Answers: # 10 has smaller quantity resistance then #12 and it is adjectives about voltage drop. The smaller number drop you have the smaller amount current you will draw which equals less warmness. If you look at the electrical formula for heat it is I Squared R=Heat surrounded by Watts as you can see with the I (current) squared purely a little more current equals a moment or two more heat (squared). Also as the line heats up the R go up.
The wiring within you house is (should) be protected from overload by a fuse or circuit breaker so there should be no issue next to it burning up.
It's not about voltage drop. It's give or take a few your protection when you use an extension cord.
It is so that the piece of equipment that is plugged into the cord does not shortout or burn up I don`t know causing you injury or worse.
the ten assess is stranded wire. Romex have solid conductors.
Voltage drop aside, you want to think amperage. Heat.
Depending on the length, check the amp rating on the appliance.
There are numerous reason for using #10 extention cords but the main plea is if you are running over 100ft. to prevent voltage drop and amperage heat up. Other than those uses #12 or #14 is fine...
