Electricity is essential for light, power, air condition, and refrigeration. Electricians install, connect, test, and maintain electrical systems for a variety of purposes, including climate control, security, and communications. They also may install and maintain the electronic controls for machines in business and industry. Although most electricians specialize in other construction or maintenance, a growing number do both. Electricians work with blueprints when they install electrical systems in factories, office buildings, homes, and other structures. Blueprints indicate the locations of circuits, outlets, load centers, panel boards, and other equipment. Electricians must follow the National Electric Code and company with State and local building codes when they install these systems. In factories and offices, they first place conduit (pipe or tubing) inside designed partitions, walls, or other concealed areas. They also fasten to the wall small metal or plastic boxes that will house electrical switches and outlets. Then they pull insulted wires or cables through the conduit to complete circuits between these boxes. In lighter construction, such as residential plastic – covered wire usually is used instead of conduit. Regardless of the type of wire used, electricians connect it to circuit breakers, transformers, or other components they join the wires in boxes with various specially designed connectors. After they finish the wiring, they use testing equipment, such as ohmmeters, voltmeters, and oscilloscopes, to check the circuits for proper connections, ensuring electrical compatibility and safety of components. In addition to wiring a building’s electrical system, electrician may install coaxial or fiber optic cable for computers and other telecommunications equipment. A growing number of electricians install telephone systems, computer wiring and equipment, street lights, intercom systems and fire alarm and security systems. They also may connect motors to electrical power and install electronic controls for industrial equipments.
