My building permit expires in December and I would like to go ahead and get the meter installed. Just had a metal garage built. I have the meter can and main panel installed, back to back on an exterior wall. I am running 3/0 cu wire for 200amp service. #4 cu ground with 2 8ft ground rods. All that said, can I install one 20A gfci outlet to pass the meter install inspection. Not planning to fully wire the garage until next year. Just need the meter installed and one outlet for now.
