Design and Specification of Switchgear versus Switchboards including PV Source Connections to Switchboards
Electrical power distribution relies on the connection of a series of several different types of distribution equipment from the power source to the load. At its core there are almost always low voltage switchboards and switchgear. Though the terms “Switchgear” and “Switchboard” are often used interchangeably and informally to describe a wide variety of electrical distribution equipment, they have precisely different specifications and testing standards; even the NEC includes a different definition of each. Whether selecting electrical equipment for a simple commercial project, a data center, or a hospital, understanding the differences are important as the selection significantly affects reliability, safety, maintenance, size, cost, working space clearances, and more.
This presentation will discuss the key differences between switchboards and switchgear for the application, design, and selection by consultants, contractors, and end-users. It will also cover the different types of circuit breakers used in switchboards and switchgear (e.g. molded case, insulated case, and power circuit breakers). Included will be photos of the internal construction and components to illustrate differences, as they are significant. This will help get beyond the single line diagrams and specifications for those who have not had opportunities to visit job sites or manufacturing plants.
In addition, since designers are increasingly working on projects with photovoltaic (PV) inverter sources, questions arise on inverter connections and configurations for switchboards. This presentation will touch on NEC compliance, bus sizing, breaker position, customer needs (future and current), and manufacturer requirements.
