Electrical Plan

Information Required
  • The electrical plan may be included on the floor plan if sufficient clarity is retained.
  • The electrical service size must be indicated on the plans.
  • The electrical plan must include the location of the service panel and its rated ampacity (ie- 150 amps, 200 amps, etc.). Show all outlets, switches, light fixtures and smoke detectors. Label any 220-volt outlets. Label all required GFCI (ground fault interrupter circuit) outlets. Low-voltage wiring and components such as phone jacks, TV, and security systems may be omitted.
  • Show the locations of all required smoke and carbon monoxide detectors. In dwelling units, a detector shall be installed in each sleeping room and a point centrally located in the hallway or access area.
    • In multi-story dwellings, a detector shall be located at each story, including basements. In split-level areas, the detector shall be located in the upper area (unless there is a sleeping room in the lower area, in which case a detector shall be located on both levels). When sleeping rooms are on an upper level, a detector shall be located on the ceiling near the top of the stairway.
    • When the ceiling height of a room open to the hallway serving bedrooms exceeds that of the hallway by more than 24 inches (such as a vaulted living area), smoke detectors shall be installed in the hallway and the adjacent room.
    • Every detector located within a dwelling shall sound an alarm audible in all sleeping areas.
  • Note on the plans that smoke detectors shall be audible in all sleeping areas (for large or multi-story structures, this normally requires inter-connection of the detectors so that all detectors activate during a fire). Smoke detectors shall receive their primary power from the building wiring and shall be equipped with battery back-up.
  • Outlets must be located in such a manner that no point along a wall is more than six feet from an outlet (each doorway starts a new wall area). A wall is defined as an area two feet wide.
  • All kitchen counter top outlets must be GFCI-protected and be spaced no more than four feet apart. Counter top spaces 12 inches wide must have an outlet.
  • Outlets located in the following locations must be GFCI-protected: garages, carports, underfloor areas, bathrooms, exterior locations, and at wet bar counter tops.
  • Three-way light switches must be located at the top and bottom of each stairway.
  • To meet Title 24 Energy requirements, show that general use lighting in bathrooms and kitchens will be high efficiency (minimum 40 lumens per watt)
  • AFCI: Indicate that all of the bedroom receptacles shall be AFCI (arc-fault) protected.
