Low Voltage AC System Design Considerations

This course is designed to help attendees understand how the design of modern, low voltage AC systems will change to accommodate distributed renewable energy sources, such as rooftop solar panels, as well as chargers for electric vehicles and updated time of day pricing. The instructor bases lessons on his work integrating modern technology and customer expectations into low voltage AC systems.

This user-friendly course is focused on critical considerations that executives, project coordinators, project managers, engineers, designers, and technicians will encounter as energy consumption is electrified and smart technology becomes commonplace.

Who Should Attend

Executives, project coordinators, project managers, engineers, designers and technicians impacted by smart technologies and the electrification of energy.

Benefits and Learning Outcomes

Recognize how the following technologies will impact low voltage AC systems:

  • Electrification of energy consumption
  • Rooftop solar panels
  • Energy storage facilities
  • Electric vehicles
  • Renewable energy
  • Time of day pricing

Upon completion of this course, participants will identify the changes that will be made to low voltage AC systems as consumers embrace widespread renewable energy sources and the electrification of energy consumption.

Course Outline/Topics

Day 1: Traditional Low Voltage AC Systems
The focus on Day 1 is assuring that all participants have a common understanding of traditional low voltage AC systems. Topics include:

  • Voltage and ampere ratings
  • Electric utility / consumer transition point
  • Circuit breaker panels and ratings
  • Sketches, diagrams and load tables
  • Feeder and branch circuits
  • Thermal magnetic circuit breakers
  • Ground fault circuit interrupters
  • Arc fault circuit interrupters
  • Cable properties
  • Loads and appliances in residences (120/240 Volt, 200 Amp)
  • Loads and appliances in stores and commercial buildings (120/240 Volt, 400 Amp)
  • Loads and appliances in industrial buildings (480 V, 600 Amp)

Day 2: Low Voltage AC Systems with Renewable Energy
On Day 2, the focus is understanding how low voltage AC systems will change as energy production transitions to renewables, energy consumption is electrified and electric utility rate structures are changed. Topics include:

  • Time of day pricing
  • Demand (KW) pricing and consumption (KWH) pricing
  • Cost reduction strategies
  • Load sequencing in residential, commercial and industrial buildings
  • Sketches, diagrams and load tables with load sequencing
  • Rooftop solar integration
  • Electric vehicle charging
  • Heat pump alternatives to traditional HVAC
  • Overvoltage / undervoltage response
  • Underfrequency / overfrequency response
