Electrical, communications, and electronics tool sets are commonly used by electricians, network technicians, assembly line workers, and others who install and repair wire and cable. Standard electrical tool sets contain uninsulated tools to turn fasteners and terminals, make connections, grip components, strip or cut wire, and perform other tasks where there is no possibility of contact with energized wiring or equipment. Insulated electrical tool sets include tools with nonconductive coatings or covers that protect against electrical shock if tools make accidental contact with live circuits. Communications and electronics tool sets have tools to install and repair data, telecom, and electronics wiring and components.
