wiring 220 clothes dryer

[Michiganspank]

Hi
I am not sure this is the correct group,
but here goes ....

I am moving a electric dryer from 1st floor to 2 floor ,so I figure
I will be running about 60 additional feet of # 10 gage wire,
so my question is at what distance would a # 8 wire be recommended ?

thanks in advance

The Canadian Electrical code allows 3% drop in a branch circuit (ie. from
panel to load).
#10 is breakered at 30 amps.
At 30 amps, a 3% drop will occur at ~105feet.
The general rule of thumb for residential wiring is to increase the wire
size
whenever the run is greater than 100 feet.
