Options for laying 12 V cable
There are two types of cable plans or methods of laying cables: linear
and split. If you have made a lighting plan then making the wiring
diagram is just a question of drawing the cable onto the garden design.
Follow an imaginary line between the fixtures. Always test the circuit
above ground before you bury the cable underneath paving or soil.
Option 1: linear
Roll out the cable from the transformer into the garden and lead it to
the various armatures. The cable can end anywhere and can have the
following maximum length:
14/2 cable up to 40 m (Fig. 7A)
10/2 cable up to 80 m (Fig. 7B)
Does your lighting plan include fixtures with power greater than 35 W?
Always use the 10/2 cable for these.
Option 2: split
Roll out the cable from the transformer into the garden. Using the cable
connectors, make one or more branches that you lead to the various
fixtures. Ensure that the ridged and the smooth sides of both cables point
in the same direction. (Fig. 9)
The maximum length of the branch or branches depends on the place
where you install the cable connector or connectors. For each branch
first calculate the length of cable from the transformer to the relevant
cable connector. Subtract this length from the maximum cable length for
the cable you are using. The remaining number of metres is the maximum
length of the branch.
You can make several branches as long as this total does not exceed the
maximum cable length:
14/2 cable up to 40 m (Fig. 8A)
10/2 cable up to 80 m (Fig. 8B)
Does your lighting plan include fixtures with power greater than 35 W?
Always use the 10/2 cable for these.
Important!
The maximum load of each cable connector is 50 W. If the total power of
the fixtures after the CC-2 is greater than 50 W, then multiple CC-2s must
be fitted. (Fig. 10). Always round up the number of cable connectors to be
used. (Fig. 11). Try to spread the power as evenly as possible along the
cable. This will benefit the light output.
Installation tips
Tip 1
Use plenty of cable for the installation. The cable will not then be under
tension if the garden subsides a little.
Tip 2
Insulate the cable ends with caps. You can do this by pulling the end
three centimetres of cable apart and putting a cap on each end. You do
not need to remove any insulation from the cable.
Tip 3
When connecting the fixtures leave plenty of cable from the fixture.
There are special extension cables (CBL-EXT CORD) of 1 metre and 3
metres available to increase the distance of the fixture to the main cable.
