One Line Diagram

Written by Jerry Ratzlaff. Posted in Designer

One line diagrams include the sizes of all loads, buses, circuit breakers, transformers, motor controllers, and presents metering and control requirements in a simple, diagrammatic manner.  It should be noted that, just like Piping and Instrumentation Diagrams, the one line diagram reflects electrical relationships and does not define physical relationships.

Information presented on the one line diagram is not duplicated on any other drawing.
