Well, to be precise, the whole story goes like this:

Before I started the renovation project, on the outer wall there was a metal box with fuses and electric connections inside. To renovate the outer side of the wall, I needed that box relocated. Unluckily, the box was secured with bolts which were behind the main electric connection. I mean, the one which connects the house to the grid. So, to relocate the box it was necessary to climb up the pole, disconnecting the wires there. And that is something I'm happy to leave for the professionals to do... Screwing up things with the main grid runs a risk of either causing half of the village going out of electricity, or then just getting myself killed by an accidental electric shock. (After surviving a hit by thunder bolt I'm not very eager to try anything like that again).

So, now I have electricity coming down from the aerial wires, all the way to the box which is now located on a temporary wooden stand near the wall. If I want a proper socket inside the house, it naturally needs a cable which is also connected into a fuse inside the box. And with so many temporary solutions and make-shift hacks here and there, I'd like to have some things finished - for example, getting the metal box back to its final place, before connecting any more cables into the fuses. And again, to get the box relocated needs a professional climbing up the pole... So, that's why I need to call an electrician to get a simple socket properly installed =)
