Good Day Code Question of the Day.
Is there a requirement for maximum distance between pull boxes or pull points in long conduit runs?

A
Answer:
Hi Ronnie,
Thank you for the question. No, there is no specific requirement for the installation of pull boxes or pull points in long conduit runs. There are however specific requirements regarding the number of bends permitted (342.26 for example). In Chapter 9, the Informational Note No. 1 to Table 1 advises that the length of the pull could have adverse effects on the conductors and may damage the conductor insulation if the size of the raceway is not given consideration. See Chapter 9 Table 1 Informational Notes.
