What to do if there is no ground wire?
If not.. If the box is not grounded, you have two choices: Run a ground to the box. This would mean running a new wire back to the panel (could be bare copper, but if you’re doing the work may be better just to run a new wire – 14/3 would be the best), which could mean opening up drywall.
Can I wire an outlet with only 2 wires?

Can you run 3 wires one outlet?

What would happen if you wire an outlet backwards?
But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
What happens if you wire a receptacle backwards?
If your outlet’s polarity is reversed, it means that the neutral wire is connected to where the hot wire is supposed to be. This may not sound like a terrible thing, but it is. There is always electricity flowing out of an outlet with reversed polarity, even if an appliance is supposed to be off.
