Single line diagrams are where upper level details like generators main transformers and large motors are shown. It is very versatile and comprehensive because it can depict very simple dc circuits or a very complicated three phase system. Schematic diagrams show the functionality of more mid level electrical circuits without getting bogged down in the details of individual connections which are shown on wiring diagrams. Basics 4 600 v 1 line.

The architectural wiring diagram can be referred to as a one line diagram. Basics 10 480 v pump schematic. The one line diagram is similar to a block diagram except that electrical elements such as switches circuit breakers transformers and capacitors are shown by standardized schematic symbols. The lower voltage is then used to supply power to the left and right rails of the ladder below.

Note that these diagrams are without a barrier or isolator fuses and surge protector for keeping it very simple and understandable. Phase 2 l1 l2 l3 ground when used.
