Industrial & Commercial Electrical Systems

During the first day, a building floor plan is used to illustrate and explain how various building electrical components work and systems are designed. On the second day, students will size various power and lighting loads from each area of the mock plant for: panels, transformers, overcurrent protection, branch circuit, and feeder sizing of conduit and wire. The example building is a small production facility with offices, support services, production, and shipping and receiving departments.

Topics covered:

• Main services, distribution systems, and transformers
• General NEC requirements for conduit, wire and overcurrent protection
• Attenuation, voltage drop and basic transformer fault currents
• Automatic transfer switch controls for emergency generators
• Basic fire alarm systems
• How three- and four-way switch circuits are wired
• Selecting the right size conduit and wire
• How an automatic generator knows when to start and stop
• How a fire alarm system knows when the circuit is broken
• Sizing motor and transformer overcurrent protection
