Once you have determined a layout, set each light fixture on the ground where it will be installed. Run the cable above ground in the location where it be installed. Attach the wire to each light fixture; many low voltage light fixtures use quick connectors to make this process simple. Then, attach the wire to the transformer's terminal screws. Before plugging the transformer in, dig a 3-inch (7.5 cm) deep trench along the wire's length and bury it in the ground. Plug the transformer in. Once the whole setup has been wired completely, position and mount each light according to the manufacturer's directions.
