I'm currently building a detached garage, we're needing to run 110 out there to power lights, door opener, and client will be using a fairly large compressor out there as well as an occassional saw, drill etc. They've requested 4 outlets & a couple of shop lights basically. Is it necessary for there to be a seperate panel inside the garage or can one simply run this off say a new 30 amp breaker from the house? I've tried getting an elec contractor out on the job, but it's a quite small job as you can see and it's way out in the sticks, so all I've asked have just flat declined or given me a date 6 weeks out when they can get to it. I kind of think there should be a sub panel in the bldg which sits about 35-40 feet behind the home. What say you elec pros?
