Switchboard basics

13:46

Dive into the world of switchboards! In this video we discuss switchboards and their vital role in power distribution. Switchboards are used to distribute electricity throughout commercial and industrial facilities. As part of an electrical distribution system, switchboards divide a power feed into smaller branch circuits. Each branch circuit is protected via a circuit breaker or fuse, and all done within a common enclosure allowing us to safely distribute and monitor power. Switchboards are routinely mistaken for switchgear and panelboards. However, each of these electrical enclosures are governed by different ratings. Erik Hurd discusses the ratings for switchgear (UL 1558), switchboards (UL 891), and panelboards (UL 67) and how these ratings affect: • Buss temperature • Short Circuit Rating • Barriers • Service Entrance • Cabling Access Erik also takes the time to explain types of switchboards such as main structure, pull structure, distribution structure and Integrated facility structure (IFS). Where are switchboards installed? Essentially anywhere low-voltage power distribution is needed: commercial buildings, multi-tenant residential housing, data centers, industrial, healthcare, hospitality, and retail facilities. Newer applications include using an IFS switchboard for mid-to-large EV charging. Erik also walks us through: Components of a switchboard structure which include frame, bus, overcurrent protective devices, instrumentation, enclosures, dead fronts, gutters, and exterior covers. The devices integrated inside switchboards are circuit protection and metering components such as circuit breakers, fuses, metering, surge protection devices, and other electrical components. We also illustrate how power flows within switchboard arrangements and their short-circuit withstand current ratings making it easy to grasp their capabilities. Finally, explore advanced safety technology options that can be found in modern switchboards. With safety becoming a greater priority, we’ll show you how these technologies enhance protection.
