This document provides guidance for the development of bus work designs for new substations and the upgrading and uprating of existing substations. It reviews the reliability of various bus configurations, environmental and aesthetic considerations, short circuit mechanical loads on bus structures, and related forces on rigid and strain buses. It also covers ampacity requirements, insulation coordination, public and personnel safety considerations, and good practices for maintenance and asset management. The document also includes the results of an informal survey and an extensive “References and Bibliography” section
