Installing low voltage lighting is a safe homeowner project because of the reduced levels of electricity. A typical low voltage lighting system uses a transformer to lower the power to 12 or 24 volts. These systems run on two wires. A black hot wire delivers the power to the light and a white neutral wire provides the path back to the source. Even through these lights use lower power, you should always work on conductors with the power turned off.

Instructions

  1. 1

    Turn off the power for the wires you are working on at your home's distribution panel. Double check the power is off by touching a non-contact voltage detector to the wire's insulation.

  2. 2

    Strip 3/8 inches of insulation off the black, white and green wire coming from the source.

  3. 3

    Loosen the terminals in the conductor cover with your screwdriver.

  4. 4

    Insert the black source wire on the right side of terminal of the conductor cover and tighten it down. Connect the source white wire to the right side terminal and the green wire to the centre terminal.

  5. 5

    Insert the light's black wire in the opposing terminal to the black source wire and tighten it down.

  6. 6

    Insert the light's white wire in the opposing terminal to the white source wire and tighten it down. Close the conductor cover until it locks shut.
