We have developed easy "rules" to follow to ensure that your low voltage system is
installed with even voltage to all your fixtures.  By following these rules, your DIY low
voltage system will be installed like a professional, and will provide you with
maintenance free years.
Low Voltage Installation Rules
  • Maximum of 5 fixtures per each #12-2 gauge wire run.

  • Maximum of 180 watts per each #12-2 gauge wire run.

  • Maximum distance of 50 feet from the first light on the run.

  • Maximum number of fixtures = 2 using the “Daisy Chain” wire method. (See picture
    below)
  • Use a center “ T ” wiring method for best results.  Where you splice your wire into the
    middle fixture first, and then "T" off to the other 2 fixtures to the right and the left, while
    staying within 25ft.  (See picture below)
  • Make all connections at the fixtures using silicon filled wire connectors, stripping back
    the insulation a minimum of 1 inch. Although a lot of manufactures supply their fixtures
    with plastic "quick connectors", we recommend that you throw those away, and use
    silicon filled wire connectors.  This will ensure that over time, dirt, bugs, and other
    elements, will not disturb the connection.
  • Use Vaseline or lithium grease on all lamp terminals.

  • Use Kleinhuis Cord grip (water-tight) connectors on all wires exiting the transformer.

  • Record which lamps you used for each fixture, including their wattages, on a separate
    sheet and keep it somewhere handy for the future.
