Introduction to Conduit Bending

What is the primary purpose of conduit bending in electrical installations?

• To make the conduit look decorative

• To route electrical wiring around obstacles and corners

• To increase the strength of the conduit

• To reduce the cost of wiring

Which tool is most commonly used for bending electrical conduit?

• Hacksaw

• Conduit bender

• Hammer

• Wire stripper

What is the standard angle for a "stub-up" bend in conduit bending?

Which type of conduit is most commonly bent using hand benders?

• Rigid Metal Conduit (RMC)

• Electrical Metallic Tubing (EMT)

• Flexible Metal Conduit (FMC)

• Liquidtight Flexible Nonmetallic Conduit (LFNC)

If you need to make a 90-degree bend with a 6-inch stub, where should you place the bender’s arrow relative to your mark?

• Directly on the mark

• Ahead of the mark by the take-up distance

• Behind the mark by the take-up distance

• It does not matter

What is the "take-up" in conduit bending?

• The amount of conduit wasted during bending

• The distance the conduit moves during bending

• The amount of conduit length consumed by the bend

• The length of conduit needed for a straight run

Which equation is used to calculate the shrinkage in a 90-degree bend?

What is the minimum bending radius for a 1-inch EMT conduit, according to the NEC?

• 2 inches

• 4 inches

• 6 inches

• 8 inches

Which of the following is NOT a common type of bend in conduit work?

• Offset bend

• Saddle bend

• Spiral bend

• Stub-up bend

When making an offset bend, what is the purpose of the offset?

• To avoid an obstacle by raising or lowering the conduit

• To connect two conduits together

• To terminate the conduit
