How to Install the Fluorescent Luminaire Disconnect (LD3C)

This guide provides step-by-step instructions for installing the LD3C fluorescent luminaire disconnect safely and effectively.

Estimated time: 30m

Tools needed:

Screwdriver, Wire strippers

Supplies needed:

Wiring connectors, Access covers

  1. Disconnect power

    Ensure the power to the luminaire is completely disconnected to prevent electrical shock during installation.

  2. Remove access covers

    Take off any lamps and access covers on the luminaire to gain access to the ballast and supply wires.

  3. Connect the male side

    Using appropriate rated wiring connectors, attach the line (black leads) and neutral (white leads) of the male side of the disconnect to the corresponding ballast leads. Ensure the male side is marked 'load'.

  4. Connect the female side

    Using appropriate rated wiring connectors, attach the line (black leads) and neutral (white leads) of the female side of the disconnect to the incoming supply leads. The female side is marked 'line'.

  5. Mate the disconnect halves

    Before mating, ensure a positive latch by pressing the latching member on the female side down and releasing it. Then, mate the male and female halves together until you hear an audible click.

  6. Reinstall access covers

    Replace any access covers and lamps that were removed during the installation process.

  7. Energize the circuit

    Turn the power back on and confirm that the luminaire is functioning properly.
