Conduit Bending and Installation Techniques Quiz…

Q: What is the primary tool used for bending rigid conduit?

Hickey bender — A hickey bender is specifically designed for bending rigid conduit.

Q: What is the standard bending radius for most conduit sizes?

6 times the conduit diameter — The bending radius is crucial to avoid damaging the conductors.

Q: Which of the following is a common type of bend?

Offset bend — Offset bends are used to navigate around obstacles or to change elevation.

Q: What is the purpose of a stub-up bend?

To bring conduit out of the ground or a surface. — Stub-ups are common when transitioning from underground to above-ground.

Q: What is the 'take-up' or 'gain' in conduit bending?

The amount of conduit shortened during a bend. — The gain refers to the length reduction due to the curve.

Q: When measuring for a 90-degree bend, which measurement is most important?

Marking point — The marking point dictates where the bend starts and is crucial for accurate bends.

Q: What should be used to protect the conduit from corrosion when installed underground?

Suitable corrosion-resistant conduit (e.g., PVC-coated) — Choosing the appropriate conduit material is essential for longevity.

Q: What is the maximum number of bends permitted between pull points?

Three 90-degree bends — Excessive bends make pulling wires difficult and can damage conductors.

Q: What tool is used to remove burrs from the inside of a cut conduit?

Reamer — Removing burrs is crucial to avoid damaging the wire insulation.

Q: What is the primary function of a conduit body?

To provide access to conductors for pulling and maintenance. — Conduit bodies such as LB, LR and T bodies allow easy access to conductors.
