Similar to the plumbing professional, the electrician is typically on site
(on and off) for the duration of the construction project.  The main
services pulls are normally underground and are installed in trenches
prior to the foundation being poured.  This allows the transformer
(typically located on the street so that the utility company has access
to be connected to the main breaker panel.  For large homes, there
will be sub-panels throughout the house at areas of large loads (ie:
pool equipment rooms for example).  The electrician will pull wires
after rough framing, careful not to over-bore or over-notch any
structural members.  He is there after drywall to install plugs and
switches and after paint to install finish trim.  He is likely on-site after
release of utilities to troubleshoot any issues and address any
changes in lighting fixtures.

Things to look out for in the electrical code include:
  • provision of receptacle outlets so that any point along a wall is
    not over 12' in distance between outlets and any wall over 2'
    long has at least one outlet
  • GFCI protection in bathrooms, kitchen countertops, jetted tubs,
    wet-bar sinks and basements
  • There must be at least two dedicated countertop outlets and
    one for the bathroom receptacles and one for laundry
  • Arc fault breakers in all bedrooms
  • A switch controlled light is all hallways, stairways, exists and in
    each room
  • A smoke detector for each bedroom, guest room, in access area
    to all bedrooms and at least one per floor.  Smoke detectors
    shall be hard wired with battery back-up.

Care must be taken when choosing light fixtures, of compliance with
Title 24 (newest version effective August 2009)
  • Kitchens. At least half the installed wattage of luminaires in
    kitchens shall be high efficacy. However, some lighting installed
    inside a cabinet may not be included in the wattage calculation
    that determines half of the installed wattage is high efficacy.
  • Other Rooms. All installed luminaires shall either be high
    efficacy or shall be controlled by a vacancy sensor or dimmer.
