Various tools used in electricity include a voltmeter, fish tape, a tape measure, channel lock pliers and a hammer. Other tools include noncontact voltage detectors, wire strippers, torpedo levels, wire testers, hacksaws, screwdrivers and soldering irons.
While an electrician may use a voltmeter to measure the voltage that an electrical cable carries, he can still use it to check whether wires are live. Electricians use fish tapes to pull cables through PVC conduits or metal. In doing so, a cable lubricant is used to assist wires to go through the pipe.
Electricians use tape measures to determine the right heights and depths of walls where electrical cables should pass. Channel lock pliers have numerous uses, such as taking knockouts out of boxes, tightening connectors and adjusting ceiling-fan boxes. Any electrical person needs a hammer to secure nail-on bracket boxes when installing electricity in homes. It is also used for driving supportive straps for electrical cables. Just as the name suggests, a noncontact voltage detector automatically tests if current is flowing through a circuit. An electrician simply places the end of the tracer on a cable or a circuit breaker to test for voltage.
While a wire stripper peels the plastic insulation off a wire, a wire cutter severs the wire into pieces. A torpedo level ensures the cables installed are straight, while a hacksaw cuts the metal. An electrician drives screws into electrical fixtures using screwdrivers and uses a soldering iron to fuse wires together.
