Electrician's power tools install and connect wire and cable to set up and maintain electrical, data, and telecom systems. They operate with greater speed and less effort than manual versions of the tools. Cable pullers and fishing systems feed wire and cable through conduit. Cable cutting, stripping, and crimping tools cut cable to length, remove its insulation, and connect or terminate it. Wire wrapping tools wind and unwind wires from terminals in electronics and telecommunications applications. Punchdown tools connect telecom and data cable to patch panels, wiring blocks, keystone jacks, and other network connectors.
