There are many methods and means of wiring the Tri-Clusters in a
light Circuit. Below are some suggestions and considerations that
cover one way to do a landscape installation:
Wire for Direct Burial
For direct burial in landscape
installations, care must be given to keep moisture from corroding
the splices. In the first three photos below, a simple displacement
type 3 conductor crimp connector is used. This connector is filled
with dielectric silicone grease.
A cap from a 35mm film roll canister was installed on the wires
prior to the connectors.
Silicone rubber sealer has been placed around the cap where the
wires pass through.
The canister is then snapped onto the cap and the assembly is
buried in an inverted orientation so that the air trapped in the
canister will displace any water which otherwise, if present, might
be inclined to flow into the canister. The silicone sealant would
have to fail first at any event.
General Wiring Concerns for Direct Burial
Wiring in Cement and other Permanent Fixtures
When a Tri-Cluster fixture is mounted in any type of permanent
structure, consideration must be given to the ultimate need of
replacement of the fixture.
In the case of a mortared rock wall, in the example above, a
flexible PVC hose is fed into the rock containing the fixture and
will serve as a conduit in the mortar should fixture replacement
become necessary. The fixture is adhered with silicone into the
rock instead of using a stronger adhesive. This also allows access
and ease of replacement if necessary.
