Electricity

I've just finished repairing the wall sockets in one of the rooms of my flat. Dammit, those Soviet habits about electrical schemes in houses and flats just drive me mad.
The neutral wire broke two days ago. And no wonder! There was a layup between aluminium and copper wires and aluminium wire started corroding. After some time, this wire crumbled and I got several sockets with phase current in both holes.
It's a good thing that I understand what the electricity is and that I can repair such things by myself:)

[Good work - both with the English and the wiring.  You could say "It's a good thing that..." or "It's lucky that..."]
