There shall not be more than the equivalent of ______ quarter bends between pull points for example conduit bodies and boxes in a run of Rigid Metal Conduit?

• A. 3
• B. 4
• C. 5
• D. 6

Answer: (B)

The key idea is that turning bends in a conduit run adds resistance to pulling wires. To keep pulls feasible and reduce damage to insulation, there’s a limit on how much bending you can have between pull points. For a run of rigid metal conduit, you should not have more than the equivalent of four quarter bends between pull points. That means you keep straight or gently curved sections within a pull point, and if you’d exceed that limit, you add a pull point (such as a conduit body or pull box) to create a new, shorter pull path. When counting, convert all fittings to an equivalent number of quarter bends (a straight 90-degree bend counts as one quarter bend, a 45-degree bend as half a quarter bend, and so on). If the total would be more than four between pull points, a pull point is required.
