8) Determine the size of Low Voltage Landscape Lighting Cable needed (Do this separately for each wire run
from the transformer):
A) Add up all the individual bulb wattages.
B) Measure the total length of each wire run.
C) From the wire chart below, determine the gauge of low voltage landscape wire required for your
runs and the transformer voltage TAP to connect the wire to:
• For optimum light output, the voltage at the lamp socket should range between
10.8 and 12 volts.

9) Split cable approximately 3”, and strip 1/2” insulation o each wire.
10) On the bottom of the terminal block push one bare wire into the hole marked “COM” and tighten the
corresponding screw on terminal block face until wire is secure. (See chart below)
[Chart for terminal screw torque specication]]
11) Push remaining bare wire into the appropriate voltage TAP as marked on bottom of terminal block (as
determined in step 8C) and tighten screw to torque specications in chart.
