Find an Electrician

Electricity is essential for light, power, air-conditioning, 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.

Electricians generally specialize in construction or maintenance work, although a growing number do both. Electricians specializing in construction work primarily install wiring systems into new homes, businesses, and factories, but they also rewire or upgrade existing electrical systems as needed. Electricians specializing in maintenance work primarily maintain and upgrade existing electrical systems and repair electrical equipment.

Electricians work with blueprints when they install electrical systems. Blueprints indicate the locations of circuits, outlets, load centers, panel boards, and other equipment. Electricians must follow the National Electrical Code and comply with State and local building codes when they install these systems. Regulations vary depending on the setting and require various types of installation procedures.

In residential construction, electricians usually install plastic encased insulated wire, which does not need to be run through conduit. The gauge and number of wires installed in all settings depends upon the load and end use of that part of the electrical system. The greater the diameter of the wire, the higher the voltage and amperage that can flow through it.

Electricians connect all types of wire to circuit breakers, transformers, outlets, or other components. They join the wires in boxes with various specially designed connectors. During installation, electricians use hand tools such as conduit benders, screwdrivers, pliers, knives, hacksaws, and wire strippers, as well as power tools such as drills and saws. After they finish installing the wiring, they use testing equipment, such as ammeters, ohmmeters, voltmeters, and oscilloscopes, to check the circuits for proper connections, ensuring electrical compatibility, and safety of components.

Maintenance work varies greatly, depending on where the electrician is employed. Electricians who specialize in residential work perform a wide variety of electrical work for homeowners. They may rewire a home and replace an old fuse box with a new circuit breaker box to accommodate additional appliances, or they may install new lighting and other electric household items, such as ceiling fans.

Although primarily classified as work for line installers and repairers, electricians also may install low voltage wiring systems in addition to wiring a building’s electrical system. Low voltage wiring involves voice, data, and video wiring systems, such as those for telephones, computers and related equipment, intercoms, and fire alarm and security systems. Electricians also may install coaxial or fiber optic cable for computers and other telecommunications equipment and electronic controls for industrial uses.
