EEI Tech Tools and Equipment Flashcards

Which tool measures electrical current in a live conductor without breaking the circuit?

Answer: Clamp meter

A clamp meter's jaws encircle the conductor and detect the magnetic field produced by current flow, allowing measurement without interrupting the circuit.

What is the primary function of a multimeter?

Answer: Measure voltage, current, and resistance in one device

A multimeter (volt-ohm meter) combines functions to measure AC/DC voltage, current, and resistance in a single portable instrument.

What is the purpose of a non-contact voltage tester?

Answer: Detect the presence of voltage without touching the conductor

A non-contact voltage tester detects the electromagnetic field surrounding a live AC conductor, signaling voltage presence without physical contact.

What does a torque wrench allow a technician to do?

Answer: Apply a precise amount of rotational force to a fastener

A torque wrench measures and limits the rotational force applied to a fastener, ensuring tightening meets manufacturer specifications.

Which tool is specifically designed to remove insulation from electrical wire without damaging the conductor?

Answer: Wire stripper

A wire stripper has calibrated notches sized to each wire gauge that grip and cleanly remove insulation while protecting the conductor underneath.

What does a continuity tester verify about a circuit?

Answer: Whether an unbroken electrical path exists between two points

A continuity tester passes a small current between two test points and indicates whether a complete, unbroken electrical path connects them.

A conduit bender is used to:

Answer: Form smooth, accurate bends in electrical conduit

A conduit bender uses a formed shoe and leverage to create precise bends in metal or PVC conduit without crimping or collapsing it.
