Conduit Bender Bender used to bend various types of Electrical Conduit. These come in many variations including hand, electrical, and hydraulic powered.
Non-Contact Voltage Testers A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter, and often suffices for checking for the presence of voltage on a conductor. Properly designed test lights include features to protect the user from accidental electric shock. Non-contact test lights can detect voltage on insulated conductors.
Lineman's Plier Heavy-duty pliers for general use in cutting, bending, crimping and pulling wire.
Diagonal Pliers also known as side cutters or Dikes): Pliers consisting of cutting blades for use on smaller gauge wires, but sometimes also used as a gripping tool for removal of nails and staples.
Needle-Nose Pliers: Pliers with a long, tapered gripping nose of various size, with or without cutters, generally smaller and for finer work (including very small tools used in electronics wiring).
Wire Strippers: Plier-like tool available in many sizes and designs featuring special blades to cut and strip wire insulation while leaving the conductor wire intact and without nicks. Some wire strippers include cable strippers among their multiple functions, for removing the outer cable jacket.
Cable Cutter Highly leveraged pliers for cutting larger cable. Armored Cable Cutters: Commonly referred to by the trademark 'Roto-Split' , is a tool used to cut the metal sleeve on MC (Metal Clad) cable.
Multimeter An instrument for electrical measurement with multiple functions. It is available as analog or digital display. Common features include: voltage, resistance, and current. Some models offer additional functions.
Unibit or Step-Bit metal-cutting drill bit with stepped-diameter cutting edges to enable convenient drilling holes in preset increments in stamped/rolled metal up to about 1.6mm (1/16 inch) thick. Commonly used to create custom knock-outs in a breaker panel or junction box.
Cord, Rope or Fish Tape Used to manipulate cables and wires through cavities. The fishing tool is pushed, dropped, or shot into the installed raceway, stud-bay or joist-bay of a finished wall or in a floor or ceiling. Then the wire or cable is attached and pulled back.
Crimping Tool Used to apply terminals or splices. These may be hand or hydraulic powered. Some hand tools have ratchets to insure proper pressure. Hydraulic units achieve cold welding, even for aluminum cable.
Insulation Resistance Tester Commonly referred to as a Megger, these testers apply several hundred to several thousand volts to cables and equipment to determine the insulation resistance value. Knockout Punch: For punching holes into boxes, panels, switchgear, etc. for inserting cable and pipe connectors.
GFI/GFCI Tester Used to test the functionality of Ground-Fault Interrupting receptacles
Voltmeter An electrician's tool used to measure electrical potential difference between two points in an electric circuit.
Other general-use tools screwdrivers, hammers, reciprocating saws, drywall saws, flashlights, chisels, tongue and groove pliers (Commonly referred to as 'Channellock' pliers, a famous manufacturer of this tool) and drills.
