Conduit Bending for Large-Scale Installations Quiz…

Q: What is the primary purpose of a bending shoe in conduit bending?

To provide leverage and prevent the conduit from collapsing. — The bending shoe supports the conduit during bending to maintain its shape.

Q: Which of the following is a common bend angle used in conduit installations?

90 degrees — 90-degree bends are frequently used for turns in conduit runs.

Q: What does the term 'take-up' refer to in conduit bending?

The amount of conduit consumed by the bend. — Take-up accounts for the length of conduit used in the bend, shortening the run.

Q: When bending multiple conduits parallel to each other, what is a crucial consideration?

Ensure all bends have the same radius and are aligned. — Alignment and consistent bend radii are vital for a neat and functional installation.

Q: What tool is primarily used for making offsets in conduit runs?

Offset bender — Offset benders are specifically designed for creating offsets.

Q: What is the most important reason for de-burring conduit after cutting?

To prevent damage to the wire insulation during pulling. — Burrs can damage the insulation, leading to shorts or equipment failure.

Q: What is the maximum number of degrees of bends allowed between pull points, according to NEC?

360 degrees — NEC specifies a limit on total bend angles to ease wire pulling. (2023 NEC)

Q: When bending rigid metal conduit (RMC), what should be considered regarding the bending radius?

Follow the manufacturer's recommended bending radius. — Following the manufacturer's recommendations prevents damage and maintains conduit integrity.

Q: What type of bender is best suited for bending large-diameter conduit on a large scale project?

Hydraulic bender — Hydraulic benders provide the necessary power and precision for large conduits.

Q: Before bending conduit, what step should you always take?

Measure and mark the conduit accurately. — Accurate marking is crucial for precise bends and a proper installation.
