Thanks for this Code Forum.
How long can a conduit to run be before you have to set a box?
Thanks for the question. The NEC does not specify a maximum distance in a conduit run before installing a pull or junction box is required. This is more of a design issue. What is a requirement is that the conduit not exceed 360 degrees of bends without having a pull box installed. See the xxx.26 section of the applicable raceway article in the NEC for this requirement.
