I am trying switch an outlet (in Guatemala) from 2 prong to 3 prong. I am not an electrician by trade, but I have read a few books, and have done it a few times at my house in the 'states. But this is a whole 'nother beast.
Coming out of the wall I have two white wires, a black wire, and a bare copper wire. All four go into the 2-prong outlet, I have white and black at the tip, and white and the bare wire on bottom. There are two wires that run in between them.
I am used to the grounding wire being the bare wire. I am also used to just having one positive and negative wire, or live and neutral as is the case with this new outlet (3-prong). I only have one black wire... so I put that in the neutral, the two whites in the live, and the bare in the grounding spot. It tripped the breaker as soon as I turned power back on! I switched the white and black wires, same result. What I am missing here?
If I just can't put in a 3-prong, that is fine.
Not sure if it matters, but both sockets are made by a company called Bticino. I don't know the model of the 2-prong, but the 3-prong is a Domino Avant p1228.
