Final answer:
To calculate the smallest length pull box necessary for a 200 ft straight pull in 2 inch conduit, we need to consider the length of the conduit and the amount of space required for the bend radius.
Step-by-step explanation:
In order to calculate the smallest length pull box necessary for a 200 ft straight pull in 2 inch conduit, we need to consider the length of the conduit and the amount of space required for the bend radius.
The bend radius is the minimum radius at which a conduit can safely make a bend without damaging the wires inside. For a 2 inch conduit, the recommended minimum bend radius is typically 12 inches. There should also be extra length added for making the actual bends.
So, to determine the minimum length pull box required, we add the length of the conduit (200 ft) with the extra length for the bends and the minimum bend radius. This will give us the total minimum length needed for the pull box.
- 200 ft (conduit length)
- Extra length for bends and minimum radius (12 inches)
Adding these values together will give us the minimum length pull box necessary for a 200 ft straight pull in 2 inch conduit.
