Howdy y'all. I am getting ready to install a new outlet for a new garage door opener in a garage and hope the expert and very helpful members of this forum can advise me. My garage is unfinished (no drywall) with no plans to finish it. It currently only has one outlet, I need to install more and have many blanks on my new panel to do so, but that is a separate project. My opener requires 120volt. I am planning on running 12 gauge NM wire directly from a 20 amp single pole breaker to a single 20 amp 120 Volt outlet. Should I use a GFCI outlet? Can I use any box for a ceiling outlet? When I do add more outlets to the garage, is 20 amps standard for power tools etc.? I was planning on running 15 amp circuits for the lights. Thanks - this forum rocks!
