Is 80ft too long for a 10 AWG wire to a garden-variety dryer, or should I go with 8 ? (trying to save \$\$ wiring it myself)...just trying to figure out where the cutoff is.

10 AWG is good for up to 30 amps. If it's a long run it could have too much voltage drop. If so you need 8 AWG.

You can use this calculator from Southwire to approximate the voltage drop at your distance. I just did a rough calculation with 10 AWG wire at 240 volts and drawing 25 amps would allow a maximum run of around 137 feet to keep the voltage drop to under 3%. Feel free to play with the calculator but my estimations would be that the voltage drop at your distance would be negligible. You should be just fine.

Thanks. I appreciate the advice, and the exact measurement comes in closer to 70', so I will feel safe with 10AWG.

Nice e-brewery project ...I will be interested in your venting solution

I just realized I had the wrong link in my above post, it should take you to the right page now, sorry about that!

And thanks for checking out my project, I will keep the thread updated as it progresses with plenty of pics. I close on my new home in three weeks so that's when the work begins!
