A run of EMT conduit contains several 90-degree bends and offsets installed between two pull points. According to NEC 358.26, what is the maximum total number of degrees of bend permitted between pull points?
- A360°
- B450°
- C270°
- D180°
Show answer & explanationAnswer & explanation
Correct answer: A. 360°
NEC 358.26 limits the total bends in an EMT run between pull points (such as boxes or conduit bodies) to 360 degrees, equivalent to four 90-degree bends, to allow conductors to be pulled without excessive damage.
Why the other options are wrong
- B. 450° exceeds the permitted limit and would make pulling conductors difficult.
- C. 270° is not the code-specified maximum.
- D. 180° is too restrictive; more bends are allowed.
Maximum Bends in Raceway
Raceways such as EMT, IMC, and RMC are limited to 360 degrees of total bend between pull points to allow safe conductor installation.
- 360° = four 90° bends maximum
- Applies between pull points (boxes, conduit bodies)
- Exceeding this makes conductor pulling difficult and risks damage
Memory trick: Four quarter-turns and stop — 360 is the pull-point cap.
