The electrical distribution system forms the backbone of a commercial electrical project. This lesson covers the estimating considerations associated with equipment such as switchboards, switchgear, panelboards, transformers, disconnects, and other distribution components. You will learn how to locate equipment on the drawings, interpret schedules and one-line diagrams, organize the takeoff, and recognize the additional components and installation requirements that must be included when estimating a complete electrical distribution system.
