Troubleshooting Errors in Conduit Bending Quiz…

Q: What is the primary cause of a 'crushed' bend in conduit?

Using too much force with the bending tool. — Excessive force crushes the conduit, especially with thin-walled conduit.

Q: If a bend is consistently 'out of square', what is the most likely problem?

Incorrectly aligning the bending tool. — Misalignment of the bender during the bend results in an imperfect square.

Q: What does 'springback' refer to in conduit bending?

The slight unbending of the conduit after the force is removed. — Conduit elastically returns some of the bend, which needs to be accounted for.

Q: When making multiple bends, what is a common cause of errors in conduit runs?

Incorrect calculations for offsets and kicks. — Poor calculations lead to alignment issues with multiple bends.

Q: What is the function of a level when bending conduit?

To ensure the bend is consistent and accurate. — A level verifies bend consistency, particularly on multiple bends and offsets.

Q: If a bend is consistently short of the desired angle, what should be adjusted?

The amount of springback compensation. — Overcompensate for the conduit returning slightly to its original state.

Q: What is the purpose of a 'fish tape' or 'pull string' after conduit is bent?

To aid in pulling wires through the conduit. — The fish tape guides the wires through the bent conduit.

Q: Which of these is NOT a common bending error?

Generating a perfectly straight bend. — Bends are always curved; a perfectly straight bend indicates no bend.

Q: What is the danger of bending conduit with an undersized bending shoe?

All of the above. — All listed errors are possible with an undersized shoe.

Q: What measurement is crucial for a successful offset bend?

All of the above. — Successful offsets need correct angles, offsets and conduit sizes.
