Q. What is the maximum degrees of bends permitted for EMT in one run?
See answer below.
A. According to Sec. 358.26, the maximum degrees of bends permitted in one run is 360°.
To reduce the stress and friction on conductor insulation, the total bends (including offsets) between pull points cannot exceed 360°.
Author’s Comment: There is no maximum distance between pull boxes because this is a design issue, not a safety issue.
