| Choosing Low Voltage Cable
After you have determined the location(s) of your power pack(s) and
fixture positions, map out a plan to indicate your runs.
IMPORTANT: Keep your runs as short as possible by avoiding unnecessary backtracking. Use the following
diagrams to help you draw out the most efficient layout for your lighting plan.
ALTERNATE WIRING CIRCUITS FOR SPECIAL SITUATIONS
| A. |
Split the load: run up to the recommended maximum distance in two or more directions from
the power pack. |
| B. |
The tee method: allows more even distribution of power to the center of a run or to a run some
distance off, i.e. across a driveway. Heavier gauge cable (10 or 12 gauge) or a double run of cable
should be used to make the tee. |
| C. |
Split tee: allows relative uniform distribution of power to both legs, i.e., to both sides of the
yard. Otherwise, the layout is the same as B. |
| D. |
Complete loop around yard: allows for relatively uniform light output.* |
* Polarity note: Be careful to connect the same wire ends to the proper transformer terminals
by noting the ridge on one side of the cable.
Optional: Use cable connectors to quickly
join 2 or more shorter cables, or change run direction. On runs over 150 feet or when more lamps
are connected to one line, consider using heavier cable (12 or 14 gauge), which will reduce voltage
drop and produce greater efficiency from the lamps.
