Difficulty: MediumElectrical Hand Tools

An electrician is selecting specialized hand tools for rough-in wiring, conduit preparation, and electrical panel assembly. Match each specialized electrical hand tool with its primary designated application.

  • Conduit reamerDeburrs the sharp inner rim of cut metal tubing to prevent conductor insulation damage during wire pulling.
  • Rotary armored cable cutterSlits spiral metal cladding on flexible shielded cable without nicking the enclosed insulated conductors.
  • Insulated torque screwdriverTightens terminal lugs to manufacturer-specified rotational force while insulating the user up to 1,000 volts.
  • Curved-jaw cable cutterShears large-diameter multi-strand power cables cleanly without flattening or crushing the conductor profile.

Answer

Conduit reamer matches deburring cut metal tubing; Rotary armored cable cutter matches slitting spiral metal cladding; Insulated torque screwdriver matches tightening terminal lugs to specified torque with 1,000 V shock protection; Curved-jaw cable cutter matches shearing large-diameter cables cleanly.
Each tool serves a dedicated mechanical and safety role in electrical work: conduit reamers eliminate sharp burrs that can pierce conductor insulation; rotary armored cable cutters cleanly sever metallic jackets without damaging internal wiring; insulated torque screwdrivers achieve calibrated fastener tension alongside 1,000 V shock protection; and curved-jaw cable cutters shear heavy-gauge conductors cleanly without crushing.

Step-by-Step Solution

1
Identify the primary function of a conduit reamer.
Matches deburring the sharp inner rim of cut metal tubing.
Sawing metal conduit leaves jagged ridges that will strip wire insulation unless reamed smooth prior to wire pulling.
2
Identify the primary function of a rotary armored cable cutter.
Matches slitting spiral metal cladding on flexible shielded cable without nicking conductors.
The tool uses an adjustable blade depth stop to score only the exterior aluminum or steel casing, leaving underlying conductors intact.
3
Identify the primary function of an insulated torque screwdriver.
Matches tightening terminal lugs to manufacturer-specified torque with 1,000 V dielectric protection.
Calibrated torque prevents loose, high-resistance terminations or stripped screw heads, while certified dielectric insulation protects against accidental electrical contact.
4
Identify the primary function of a curved-jaw cable cutter.
Matches shearing large-diameter multi-strand power cables cleanly without crushing.
Bypass curved blades capture round conductors and apply even shearing force rather than flattening or fraying heavy strands.
