A branched electrical system is adapted for providing multiple users with access to high and/or low voltage electrical power in work areas or high density seating areas, such as stadium or theater seating, work rooms, lecture halls, and public transportation vehicles. The system includes a main line and a plurality of branch lines, each branch line having at least one high voltage or low voltage electrical receptacle that is accessible to a user located at the seating, such as for powering a portable electronic device. The branch lines may be coupled to the main line via a splice or other electrical-mechanical connection.
