Chapter 14, Problem 1PA
A parking lot is 275 ft by 200 ft (Figure 14-23). A trade size 4 conduit has been buried 2 ft beneath the concrete. The conduit runs at an angle from one corner of the parking lot to the other. Two pull boxes have been placed in the conduit run. The pull boxes are equally spaced along the length of conduit. Your job is to pull conductors through the conduit from one end of the run to the other.
FIGURE 14-23 Determining length.
Allowing 12 ft of extra conductor, what is the length of each conductor? The conductors are not to be spliced.
How much cable will be required to pull these conductors through the conduit, allowing an extra 5 ft at one end that is to be connected to the pulling device and 3 ft extra that is to be used to connect the conductors to the cable?
