    You have a couple of choices. The best is to hire a local qualified professional electrician to do the work.

    Next is to get a copy of all of the local applicable codes and take out a permit yourself and take chances about passing the inspections. Worst is get information from someone in the other part of the world who has no idea what your local codes are or where you live. I suggest you hire the electrician.
