Panel Systems are an integral part of ETAP. They are used for representing power and lighting panels in electrical systems. ETAP provides a comprehensive model for designing and scheduling AC panel systems including 3-Phase and 1-Phase panels.

A panel is a collection of branch circuits feeding system loads. ETAP supports an unlimited number of circuits within a panel. A branch circuit in a panel is modeled with complete details, which includes connected load information, protective device ratings, and feeder data. The ETAP panel model is supported by comprehensive breaker, fuse, and cable libraries. Default and typical data are provided to save you time and money when designing and scheduling panels. ETAP allows you to graphically connect subpanels to upstream panels. There is no limit to the number of subpanels you can connect.

The Panel Schedule Editor provides a user-friendly graphical interface with a lot of suitable default values and built-in electrical intelligence. The panel schedule fields are designed in a manner to minimize data entry errors, while eliminating the repetitive task in completing panel schedules.
