I have an unused 20amp circuit in my box now that I replaced my electric dryer with gas. I'd like to use it to run a new line out to my garage (about 30-40ft from the box), put in a small subpanel, and then completely rewire the garage as it's a mess right now and underpowered (currently uses a 15amp circuit). I've read elsewhere on the forums about using direct bury cable, but how deep will that have to be buried as I live in Western NY, which has cold winters? Also, any advice on how to get it out of the house and into the garage in a way that is protected from the elements? Use conduit perhaps? Thanks for any advice.
