Landscape Low Voltage Yard Installation

Attach the end of the lighting cable to the transformer, which steps down standard household voltage to low voltage, by screwing the wires in place, typically on its back. Mount the transformer using the drill and an appropriate bit with a wood screw or masonry lag shield next to an outdoor GFCI outlet.

Assemble the lights according to the manufacturer’s instructions. Lay the lights in their installation spots.

Run the lighting cable across the ground, following your preferred design. The wiring can be organized in a single straight run, multiple straight runs, a loop, or with a main line and a cross line in a T shape. For more complex cabling designs, cut and fasten cables with weatherproof wiring connectors.

Attach the cable connectors to the cables by snapping them over the cable to power the lights. For a stronger connection, cut off the cable connectors and attach the wire to the cable with a weatherproof wire connector. Plug the transformer into the outdoor receptacle to test the lights and set its timer.

Bury the cables after testing the system by cutting slots in the turf with a flat-nosed shovel. Fold back the sod, press the wire at least 6 inches deep and push the sod back in place.
