An additional circuit vent is required after what angle change?

• A. 90 degrees change
• B. 0 degree change
• C. 45 degrees change
• D. 180 degrees change

Answer: (C)

When running cables in conduit, each change in direction makes pulling the conductors harder and increases the risk of kinks or damage. To keep installation practical and allow for easier future pulls, an additional vent or pull point is placed after a bend that reaches a certain angle. That angle is 45 degrees: a bend of 45 degrees or more is enough to justify adding a vent to maintain ease of pulling and access for maintenance. A straight run (0 degrees) doesn’t need this, while very sharp turns (like 90 or 180 degrees) would typically require a pull point earlier in the run, so the threshold is set at 45 degrees.
