    Where are you in the world? 2 blacks in the us would normally be 240v someone may have pulled in the wires for a air conditioning unit and you would not have a neutral. I would measure the voltage or find the breaker that controls this if still connected in the service panel.

  • 2 blacks may also have been for a switch. But regardless, and more importantly, Green usually means Ground, and you CANNOT use a ground wire in lieu of a Neutral wire.
