Figure  2-15.—Electrical  site  plan. Figure 2-15 shows a simple electrical site plan. This plan  shows  the  routing  of  a  new  13.8-kilovolt  (kV) primary  service  line  to  a  new  dining  facility.  The  new service  is  tapped  to  an  existing  13.8-kV  overhead primary  feeder,  runs  down  existing  pole  Number  126, and then runs underground to a new pad-mounted 75-kilovoltampere (kVA) transformer located next to the new facility. Although  a  competent  Construction  Electrician  or contractor could install this new service line from only the site plan, as shown in figure 2-15, he would have to prepare additional drawings or sketches to show his workmen  the  specific  details  of  the  construction. Therefore,  to  provide  a  better  description  of  the installation,  the  electrical  designer  prepares  additional electrical  details. Electrical Details The purpose of details is to leave little doubt about the exact requirements of a construction job. In pre- paring  the  details  for  the  installation  shown  in  figure 2-15, the designer chose to begin at the existing pole and work towards the new transformer pad. Figure 2-16 is a detail of the existing pole. This detail leaves little doubt about the requirements at the pole. For example, it shows the existing pole, crossarm, the existing 13.8-kV feeder, and required clearance distances. It also shows that the new circuit taps the existing conductors and then 2-12
