A CAD suite that integrates the general layout of underground conduits, three-phase 380/220 V power supply routes, and the location of switchboards, mailboxes, and streetlights on a school campus with athletic fields and auditoriums. It includes a single-line diagram of the TGN, a conductor panel, a graphical symbol legend, and a load table, optimizing the design and verification of installed power and maximum demand. Ideal for electrical engineers developing low-voltage projects in large-scale academic facilities.
