ElectricianYou enter a dark room and press a switch; suddenly the room is no longer dark. Have you ever wondered how electricity works in your business or home? Electricians study how to install wiring and electrify internal and external spaces for comfort and safety. While most people take the electricity we use for granted, electricians must know and ensure that every detail is perfect. Careers in the electrical industry require dedicated professionals who spend many hours of study learning how to safely create lighted spaces and outlets for electrical components and use. Electricians must be certified and educated in electrical safety and techniques. Electricity was first tested by Benjamin Franklin with his famous kite and lighting experiment (http://www.ushistory.org/franklin/info/kite.htm). Before the kite experiment, he had a lightning rod installed on the roof of his house for electrical experiments. (http://www.ushistory.org/franklin/info/kite.htm). After Franklin, Thomas Edison created light for our homes and businesses, and it was the beginning of great advances in electricity. Not only did he create the light bulb, but he also invented the microphone, electric pen, telephone receiver, battery, and many other inventions before his death. Edison had 1,093 inventions that helped revolutionize what is now known as electricity (http://www.fi.edu/learn/sci-tech/edison-lightbulb/edison-lightbulb.php?cts=electricity). The 19th century was when electricity really began and became a widespread innovation (A,93). In 1967 the law required master electricians to be licensed and insured (E). Incredibly, there is electricity in our body using the nerve... the paper medium... and the pliers (Electrician 621.319). Once all the wiring is connected to the lights and outlets, they use a circuit tester. The circuit tester measures voltages and the presence of electrical energy (electrician). Power tools are also very useful tools for construction and maintenance electricians; they use tools such as saws and drills. They mainly use tools that would help them do the job faster and quickly pull a wire through a conduit (electrician). Line operators use larger tools and machines to do their jobs. Cranes and hoists are often used by line workers to install utility poles (electrician). They can also use remote-controlled robots to reduce the dangers of high voltage cables (electrician). Hot sticks, long tools used to protect them from electric currents, make sure to use insulated tools and wear insulating gloves (electrician).
