Look back - electricians and their wires
The first interior power wiring systems used conductors that were bare or covered with cloth, which were secured by staples to the framing of the building or on running boards. Where conductors went through walls, they were protected with cloth tape. Splices were done similarly to telegraph connections, and soldered for security. Underground conductors were insulated with wrappings of cloth tape soaked in pitch, and laid in wooden troughs which were then buried. Such wiring systems were unsatisfactory because of the danger of electrocution and fire, plus the high labour cost for such installations.
Where electricians can seek employment?
Large industrial plants require continuous supervision by electricians. In such places, electrical work, after-hour, including the usually public holidays and so on. Often continuity of production makes the conduct of such processes is profitable. Production plants are often places where electricity specialist can find a well-paid job. This involves a number of responsibilities for the most number of installations. Moreover, work in the industry can find a lot of people, because the large volume production is accompanied by high employment, also in the field of electrical engineering.
Modern car parks
Actually, more rarely we encounter a situation where the parking lot waiting for us the person collecting the fee for parking and issuing the appropriate tickets. Commonly used are now automated systems that allow you to dispense with the employment service in the parking lot. Customers themselves, usually using the touch panel choose certain options standstill. After driving into the parking traveled with him it is possible only upon payment of the appropriate fees and scanned the ticket. Parking systems are designed so that the most common problems that may arise during their lifetime the irregularities in the electricity and then the appropriate repair must address electrician.
