Electrical wire is used in residential, commercial and industrial buildings in order to wire lights, appliances and other electrical devices. Electricians may thread electrical wire through the walls of a building in a residential setting, while they may have to thread wire under the floors or in the ceilings in commercial and industrial settings. Electricians use a variety of tools in order to thread wire.

Electricians must run wire through the walls or floors in residential homes. The electricians do this by drilling round holes through wall studs using a hole saw. A hole saw is a drill with a round bit attachment that features small metal teeth. These holes are made in varying sizes, depending on the diameter of the wire that must be threaded through the walls. In most instances, these holes are only an inch in diameter. Once an electrician drills these holes, he can run the wire through the wall studs to the desired destination.
Wire is usually threaded by hand in residential settings, but commercial and industrial jobs may require thousands of feet of wire to be pulled. Wire pullers, also known as cable tuggers, connect to the end of a roll of wire, which is attached to a large spool. A small motor on the wire puller will then use thousands of pounds of pulling force to drag wire off a spool and through a conduit. This tool saves electrical workers a significant amount of time and effort. For example, the Pull-It 10K uses a small motor to pull wire at between 9 and 25 feet per minute, depending upon the gauge (thickness) of the wire.
Since wires are usually insulated with a soft plastic covering that is difficult to grip with the hands, electricians usually use pliers in order to pull wire through holes when threading the wire. Electrician pliers feature an inner sharp edge for cutting wire and raised teeth on the end, so that you the electrician can gain a solid grip on the end of a wire strand.
Another tool used when threading wire is electrical staples. Staples fit over the top of a strand of wire and are hammered into place, which secures the wire. This is important when wire pulling, because staples prevent the electrician from pulling a strand of wire too tightly when threading it through walls.
Sometimes wire cannot be threaded easily because it catches on rough edges in walls and conduits. In this instance, wire pulling lubricant will be used. Greasing the wire will allow the electrician to pull wire through tough spaces without the risk of stripping away insulation, which could cause a fire.
