Not neccessary. 30' is not a long distance. 10/3 on 30 amp breaker is fine.

Agree. With a 50 foot 240V run, you'll experience very little voltage drop. For a standard dryer, bumping to #8 is a waste of money.

Just out of curiosity, where'd you get this advice?

terribletom,

I got the advise from an electrician that said since I have a high end dryer which draws a bit more than a standard dryer and since the run was going to be 50 feet, I should consider the #8. I am all for saving money, but not where electric is involved. I am adding this run while my walls are all stripped bare for the remodel. Can't change it later without tearing everything up. I am just in the planning stage and want to have all my ducks in a row. If you feel #10 will work with no issues, I will use it. Just want to make sure. thanks for the respone.

Thanks bigbird. Your response made me LOL. He probably does have a roll of #8 sitting around. I will be using #10. Thanks to everyone for the responses. This site has never failed to answer one of my questions.

If he is trying to use up extra #8, ask him if he can supply it for the same price as #10.
