10 AWG for 120' run?


I am planning on running electrical from my breaker panel at the house to a garage. The total run will be about 120 feet. The garage has a refrigerator and a freezer in it, as well as a few lights.

About 20% of the way down the 120 foot run, I want to put an outlet for outdoor use (lights, maybe an electric smoker in the future, etc.)

The 120 foot run will be in conduit and I plan on using outdoor rated wire. The question is, should I use 10 AWG or is 12 AWG sufficient? If I use 10 AWG, what size breaker should I use?

I was thinking about running the 120 foot run as one run, and then doing a separate run along side it for the outlet about 30 feet down the line. Can I connect them both to the same breaker?

Thanks for your help!

You can not install more than a 20 amp breaker on it if you want normal duplex receptacles.

Got it. Overall is that run length ok with 10AWG and a 20 amp circuit?

I'm assuming it's a detached building. You'll want a sub panel out there instead of an individual circuit.
