That is correct, pull boxes are not required every 100 feet. It is good trade practice for many reasons (most fish tapes are only 100 feet) but sometimes it's not possible. Imagine runs of conduit in a slab or underground parking lot lighting, every 100 feet would be a pain. It's fairly standard/typical, that the electrical specs for water utility/public works projects, require UGPBs for branch circuits and control wiring to be strategically placed in 200' .

I know he original post concerned the length of 3/4' conduit between pull boxes .I am from the Caribbean, we do have a local electrical code which specifies a maximum of three 90 degree bends and 120 feet of conduit between pull boxes. But the idea of using a vacuum cleaner and a plastic bag to pull in a pull-line is a very unique idea. We have a large piece of property (approx. 5 acres) where we will be running many PVC conduits in trenches for power, phone, TV, security, etc. and is there a maximum distance allowance of a continous run of PVC pipe where we need to install pull points (christy boxes). I know we cannot exceed.

What is the maximum distance between electrical pull boxes? The NEC specifies the maximum distance between electrical pull boxes based on the size and number of conductors to ensure proper conductor bending radii and accessibility. How many cubic inches must a box have to house one #10 AWG conductor? The distance between electrical conduit pull boxes where there are bends depends on the location of the bends and *their* distances apart, since the NEC 300-13(a) says “There shall be no more than the equivalent of four-quarter bends (360 total) between pull points.” Details: The distance between pull boxes will depend on the number of . One key point is that on straight pulls the box or conduit body length must be at least eight times the trade size of the raceway.
