Electricians connect all types of wires to circuit breakers, transformers, outlets, lighting fixtures 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 amp meters, ohm meters and volt meters, to check the circuits for proper connections, ensuring electrical compatibility and safety of components

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