Hi Tamrat
8 years ago, I attended a funeral in Gerji and was shocked at the standard of domestic wiring there. So much so, I offered Addis University a free course on Domestic Wiring for existing and new electricians. I set up the course with the Uni's Head of Electrical Engineering and got test equipment manufacturers and the IET to supply test equipment and Regs and OSGs. (about £5,000 worth) I had all these course materials shipped to Addis, but Customs were uncooperative and eventually they said they had "lost" the shipment, so it was cancelled.
I've been back several times since and on one occasion, drove past an overhead electricity line with a guy dead and frying on it, until they isolated the line.
I am not surprised you are terrified of being electrocuted.
