I have a dryer socket rated to 40 amperes and the wire feeding it is 10/3 nm-b and the breaker is 40 amps, this was done by licensed electricians back in 2001. I know this is a violation as you are supposed to use the 60c amperage, not 90c. Was it code back then or not? If it wasn't then is there any tricks to pulling 8/3?
It is permissible to use 10/3 nm-b for a dryer. However, it should be on a 2P30A breaker, not a 40. All of the electric dryers I've ever installed (or seen installed) have been 30A. Check the info on the dryer for the proper sizing of conductors. If it calls for a 40A circuit then you'll have to run 8/3. No special tricks that are different than pulling other wires; Be careful, be safe. pete
