Design an electrical plan.

Design should include freehand sketches and consultation of architectural product catalogs. The designer must consult the given floor plan and the National Electrical Code (NEC) and calculate

  • the number of general lighting circuits and required wattage
  • the number of special appliance circuits and required wattage
  • the number of individual appliance circuits and required wattage
  • total wattage and amperage requirements.

Design should also include selecting

  • a distribution panel based on amperage requirements
  • lights, types of switches, and switch locations
  • outlet locations
  • location for the distribution panel and meter base.

Process/Skill Questions:

  • What are some consequences of failing to follow NEC guidelines when designing an electrical system?
  • What factors influence the location of switches and outlets?
  • How is size and specification of the distribution panel determined?
  • What factors influence the location of the distribution panel and meter base?
