At this stage the engineer can begin to prepare a load schedule for each subsidiary switchboard and motor control centre, and a master schedule for the main switchboard. The development of the single-line diagrams during the project is discussed in sub-section 1.7.

The next fundamental design document for plant electrical engineering is the single line diagram, very much the electrical equivalent of the flowsheet. This document is not the exclusive preserve of the electrical engineer it requires the input of the process and mechanical engineers. Its format is dependent on the following.
